Fixing the Calendar - by doing absolutely nothing.

The Calendar the modern world uses is ten days off the mark.

Yes.

This is true.

If January 1st of the Calendar is meant to mark the beginning of the new celestial year, then the Calendar is 10 days off the mark.

The new Celestial Year begins on what is now December 21st. You may recognize this as the Winter Solstice.

To align the modern Calendar with the Winter Solstice all that has to be done is absolutely nothing for 40 years. By "absolutely nothing" I mean that we have to ignore Leap Years for ten cycles of Leap Years, and since a Leap Year happens every 4 years, that tallies up to 40 years.

If we do this, then in 40 years the modern calendar's January 1st will coincide with the Winter Solstice.

That's not all!

After said 40 years of doing nothing except ignoring Leap Years, the Celestial Seasons of the year will be conveniently marked by blocks of three months.

Winter = January, February, March

  • equinox

Spring = April, May, June

  • solstice

Summer = July, August, September

  • equinox

Autumn = October, November, December

  • solstice

And, the beginning and end of each Season would be marked by a Solstice or an Equinox. At present the modern calendar has the solstices and equinoxes lost amongst the days of the months, instead of the solstices and equinoxes punctuating the beginning and end of seasons at the beginnings and ends of months.

So, by doing absolutely nothing for 40 years we can adjust our modern calendar to the actual seasons of the year and the Earth's orbit around the sun. Isn't that what the Calendar was invented for?

Powder Horn Lichens Clarified

Quotation from the Notes from this link: https://lichenportal.org/cnalh/taxa/index.php?taxon=53390&clid=1048

Lichen terms used in the quote, and their meaning:
thallus Not in the quote below. Lichens, whether tiny and dust-like or large and dinner-plate-like, or ribbon-like, or shrub-like, have the main body made of a stacked layer of cells called a "thallus". The thicker the stack, the more differentiated the cell layers tend to be - no surprises there.
squamule = small thallus: Note: All lichens have a thallus. The Cladonia species are small lichens and thus have small thalli, and lichenologists call these small thalli "squamules".
podetium (plural = podetia) You may know the word "podium", and a podetium might as well be called a podium [autocorrect strongly agrees - try writing the word "podetium" and see what happens!]. The Cladonia species of lichens hold/present their spore-bearing structures at the end of a podium, sorry, podetium. The shape of the podetium varies from species to species, and can be useful in identification.
corticate like rough tree bark
rugose furrowed, like corduroy cloth
soredia A botanist would use the term "gemmules", for soredia. Soredia (and gemmules) are packets of cells that are clones (have exactly the same genetic material) as the lichen (plant); each soredia (gemmule) is capable of growing into a new lichen (plant). Soredia (and gemmules) are a means by which the lichen (or plant) clones itself.
soralia A structure that produces soredia. The shape of the structure can be useful in identification.
farinose powdery texture of wheat flour
erumpent Eruptive; bursting forth through the surface. So why not just say eruptive?

"Cladonia coniocraea and C. ochrochlora are morphologically very similar, and some authors are inclined to unite them. The present treatment is provisional. The squamules of C. coniocraea are always deeply incised, whereas the margins of the squamules of C. ochrochlora can be nearly entire. Cladonia coniocraea is usually found without cups, but C. ochrochlora rarely lacks them completely. The base of the podetium in C. coniocraea is only thinly corticate, while the cortex of C. ochrochlora is thick, extends beyond the immediate base, and is often longitudinally rugose. The soredia of the present taxon are usually farinose, rarely occurring in small, diffuse soralia; soredia in C. ochrochlora are variable, but are usually larger than those of C. coniocraea, and often largely occur in well defined, erumpent soralia. The podetia of C. coniocraea are greenish rather than gray, fairly slender, usually not more than 1.5 mm diameter, and are usually straight. The podetia of C. ochrochlora have a grayish tint, are generally thicker, and are often somewhat branched and twisted (Hammer 1993)."

"The base of the podetium in C. coniocraea [Common Powderhorn] is only thinly corticate, while the cortex of C. ochrochlora is thick . . ."

Translation by yours truly . . .

The base of the horn-like podium in Common Powderhorn, Cladonia coniocraea has only a thin bark (is often smooth), while the bark of the Smooth-footed Powderhorn, C. ochrochlora is thick. Yes, you read that correctly, and yes, I translated it correctly. The Smooth-footed Powder Horn actually has a rough foot, whilst the Common Powderhorn tends to have a smooth foot. It is all clear as mud.

If a common name is to be helpful, it should be, well, helpful.

Rock Tripe Lichens, a Limited Guide

First published: 24 November 2021 not copyrighted, use as you wish Michael Papay
Most Recent Update: 27 September 2022

I have learned more about the Rock Tripe Family, and offer this limited guide to identifying some of them. Descriptions are for mature/large thalli.

Upper Surface adorned by raised wart-like protuberances - Lasallia species

  • Lasallia papulosa (1) upper surface when dry in shades of gray, although the range of colors possible includes white, lavender, orange, near yellow; also, upper surface crowdedly adorned with raised wart-like protuberances; (2) underside is tan to gray or gray-brown whether damp or dry; (3) thallus mostly flat against the rock surface https://www.inaturalist.org/observations/100618252
  • Lasallia pennsylvanica (1) upper surface when dry a nearly uniform dull brown to dark brown ; also upper surface usually somewhat sparsley adorned (not crowdedly packed) with raised wart-like protuberances; upper surface usually wrinkled like a scrunched-up carpet; when damp the upper surface is dull pea-green to brown-green that looks almost greasy; (2) underside is black-to-dark brown [becomes dull brown with age when the black cells have worn away; recognition of the color range of the underside consolidates observations with upper surface color and texture as described above]

Ornamented-Surface Umbilicaria

  • Umbilicaria muhlenbergii (1) upper surface adorned by sunken dimples, especially at periphery, and the dimples are where black reproductive structures (apothecia in lichenological terms) are produced; almost unfailingly a very dark brown lichen when dry, and green when damp; (2) underside coarsely textured at the periphery (not a uniform fine-grained near planar surface) (3) black apothecia (reproductive structures) are produced in sunken dimples at the periphery of the thallus https://www.inaturalist.org/taxa/504634-Umbilicaria-muhlenbergii
  • Umbilicaria phaea (1) Upper surface smooth and entire, (if surface is fissured, the fissures are at the periphery of the thallus whilst the central area of the thallus is smooth), (lacks sunken dimples or raised warts), is dark brown when dry (like U. muhlenbergii ), and is adorned with black flat (usually), geometric in outline structures (apothecia) with concentric geometric lines within https://www.inaturalist.org/taxa/125055-Umbilicaria-phaea
  • Umbilicaria torrefacta (1) Upper surface smooth but fissured like a sort of jigsaw puzzle of melded piece akin to fault lines at junctures of continental plates (lacks sunken dimples or raised warts), is usually dark brown when dry, but color can include frosty tans to white (like U. muhlenbergii ), and is adorned with black flat (usually), geometric in outline structures (apothecia) with concentric geometric lines within https://www.inaturalist.org/taxa/233255-Umbilicaria-torrefacta NOTE: Not always morphologically nor chemically distinct from Umbilicaria hyperborea.
  • Umbilicaria hyperborea (1) Upper surface distinctly and abundantly blistered, otherwise somewhat similar to Umbilicaria phaea NOTE: Not always morphologically nor chemically distinct from Umbilicara torrefacta.

Smooth-surface, un-adorned Umbilicaria (Upper surface smooth: not adorned with numerous raised wart-like protuberances, nor with sunken dimples, nor with tiny raised dots)

  • Umbilicaria mammulata Two color forms identifiable when dry: (a) the common dark tan to brown to dark brown; (b) the less common near-white, being light tan at the periphery and near-white at the center. (1) upper surface when hydrated is green, when dry is brown to tan to near-white; outline of lichen usually irregular in shape; thallus lobes unequal, the larger lobes actively fold over the main thallus in dry conditions, and unfurl in damp conditions (2) underside black, very fine-grained ( very short false rhizines) (3) the black apothecia (reproductive structures) are spheroidal and occur on top of the upper surface, are not in sunken dimples nor slightly impressed into the surface https://www.inaturalist.org/observations/136615751
  • Umbilicaria americana (1) upper surface when damp is light-green, drying to very white; surface at periphery sometimes peppered with small black dots; outline of intact lichen roughly circular, peripheral lobes regular in shape, usually only shallowly incised; (2) lower surface usually adorned with a thick short false rhizines [rhizine is a technical term for what are effectively roots of a lichen], giving the lower surface a somewhat shaggy appearance. Umbilicaria americana is known from non-acidic rocks, usually limestone or dolostone, but amphibolite and any non-acidic rock might, in theory, do. https://www.inaturalist.org/taxa/182508-Umbilicaria-americana
  • Umbilicaria duesta Small rock tripe lichen, (1) dry surface deep brown, periphery with numerous black dots; upper surface fine granular texture; thalli small, usually crowded, generally curled under at edge and thus sort of ear-shaped, https://www.inaturalist.org/taxa/182503-Umbilicaria-deusta

Dermatocarpon Rock Tripe Lichens (surface peppered with regular small dark dots; thallus thick and the edges smoothly rounded-over, not thin and papery)

***Solidago curtisii***

NOTE: As of 24 September 2021 I have differentiated, by observation and measurements, that
1) Solidago caesia has

  • inflorescence that comprises more than half the total stem, often as much as 3/4 of the stem
  • the internodes of the inflorescence separate the flowering portions
  • the widest non-basal leaf is less than 30mm wide, usually less than 25mm wide

2) Soidago curtisii has

  • inflorescence that comprises half or less of the total stem length
  • internodes that bear flowers are closely spaced, the flower so closely spaced as to present a flowering rod at the end of the stem
  • the widest non-basal leaf is more than 30mm wide

Of the 49, at present [13 September 2021] "Confirmed" observations of Solidago curtisii
1) only three have very narrow leaves:
a. https://www.inaturalist.org/observations/94330036 - very narrow toothed leaves
b. https://www.inaturalist.org/observations/32649260 - very narrow toothed leaves
c. https://www.inaturalist.org/observations/13941999 - very narrow toothed leaves

2) Of which only 1a. provides a view of the abaxial/lower leaf surface, and it is glaucous white https://www.inaturalist.org/observations/94330036

The glaucous white abaxial surface is very different from the green, non-glaucous, abaxial surface of the other Solidago curtisii observations.

I suggest that the combination of very narrow toothed leaves with glaucous abaxial surface is sufficiently distinct that it should be investigated as a separate or sub-set taxon from Solidago curtisii.

VARIATION OF SEPAL TRAITS IN STELLARIA PUBERA

Stellaria pubera and Stellaria corei

Present taxonomy would place a Stellaria pubera with:
(1) sepals as-long-as or longer than the petals; and
(2) sepals whose underside/abaxial surface is smooth/bald/glabrous
as Stellaria corei, originally described as a subspecies of Stellaria pubera.

However, it is apparent (see iNat observations below) that individuals of Stellaria pubera can have:
1) long pubescent sepals
2) long glabrous sepals
3) short pubescent sepals
4) short glabrous sepals

How can this be?

  • Stellaria corei is a tetraploid (4n) version of the diploid (2n) Stellaria pubera. Stellaria corei likely originated when an error in meiosis resulted in un-reduced gametes [the pollen and egg were not haploid (1n) as usual, but were instead diploid (2n), and when combined (fertilization) resulted in a tetraploid (4n) individual. This sort of thing is common in the cactus genus Opuntia.]
  • Stellaria corei (4n) can interbreed with Stellaria pubera (2n) and produce viable offspring (3n). The offspring will be sterile due to their triploid (3n) genetic composition. The triploid plants can, however, reproduce vegetatively (by rooting at stem nodes, root division, et cetera).
  • The triploid hybrids (Stellaria corei x pubera & Stellari puberi x corei) will present a mixture of traits of the parents, and be difficult or impossible to visually separate - until such time as an in-depth study is conducted across the breadth of the distribution of both species, and hybrids, that includes documentation of physical traits combined with genetic analyses. Only in this way will convincing knowledge be produced to determine whether any physical traits can definitively (statistically significant) be used to separate the species, and the hybrids from the species.

That being said, only 1 observation has been found (as of 23 May 2021) of a Stellaria pubera with pubescent sepals that are longer than the flower petals [this may be a triploid]. I therefore tentatively suggest that

  • combined traits of (1) truly glabrous sepals that are (2) longer than the petals can reliably be attributed to Stellaria corei
  • combined traits of (1) definitively pubescent sepals that are (2) shorter than the flower petals can reliably be attributed to Stellaria pubera
  • Triploid intermediates are expected to exhibit (1) a range of degree of sepal glabrousness and pubescence and (2) a range of sepal length (shorter-than or longer-than the flower petals). When the plant is neither emphatically glabrous, or emphatically pubescent then it may not be far off the mark to consider it a triploid.

What to do with the triploids? A situation that perplexes current taxonomy.

Below are iNaturalist observations of Stellaria pubera

The Christmas Fern, Polystichum acrostichoides, in the un-glaciated lower Piedmont and Triassic basin of North Carolina, exhibits the diversity of color and form indicated below. erwin_pteridophilos (@erwin_pteridophilos) advised that the source of the variation may at least in part be due to the expression (phenotypic re-emergence) of ancestral genes. This appears to be corroborated by observations of individual Polystichum acrostichoides with completely separate fertile fronds (unlike the usual situation in Polystichum acrostichoides where the fertile section is located at the end of an otherwise sterile frond), and in individuals with twice-divided fronds (unlike the usual once-divided fronds of this species).

What variation occurs in previously glaciated realms? Are populations there more diverse? Less diverse? Differently diverse?

I have not encountered (observed) individuals with long, wide pinnae (leaflets) outside of the Triassic Basin, and then only in lowland mesic areas. They are absent (or scarce?) in adjacent uplands where usual forms still abound.

THE FIRST PLANT - Photosynthesis without sunlight.

THE FIRST PLANT (Photosynthesis without the sun!)

Submitted for your consideration, my speculations on the origins of chlorophyll that were very soon proven true by persons who had no idea that I had predicted their discovery whilst simultaneously I had no idea that they were trying to discover it. What? It is like this. In 2017 whilst rewriting the section on Synonymy, I got to thinking about the spectrum of organic molecules in comparison to the spectrum of light. I had a flash of inspiration. Where, I had been wondering, did chlorophyll come from? What was its original funtion? That’s when it struck me. The spectrum of light! We are not accustomed to thinking of heat as light – but it is! Heat is infrared light. And heat was and still is present beneath the ground and at the bottom of the sea in massive quantities, radiating from the earth’s core and mantle. I thought, What if chlorophyll was first used to harness infrared light? It made sense. Life on earth probably began below ground or under water where it was exposed to infrared light. Any organism that could harness infrared light would have the advantage of an almost limitless source of energy! So, I thought chlorophyll might first have photosynthesized infrared light/heat, and only later, when organisms were exposed to sunlight, did a slight modification of the original chlorophyll molecule allow the use of red light from sunshine, the form of photosynthesis we are so familiar with today. I fancied there were descendents of the ancient infrared-harnesing plants at deep-sea vents, and at hot springs like those at Yellowstone National Park. As it so happened, on February 10th, 2018, Christopher Todd Glenn gave a talk at the JC Raulston Arboretum about a North American Rock Garden Society field trip to Wyoming, with a side trip to Yellowstone National Park. Before the talk I approached Mr. Glenn and asked him what he thought of my notion that chlorophyll might have originally been used to harness energy from heat, infrared light. Mr. Glenn pondered a moment, smiled broadly, then suggested the subject would make a nice Master’s Thesis project for me. I wanted to say, I already have a Master’s Degree, but smiled gratefully and thanked him for taking a moment to consider the idea.

Well well well what do you know, a few months later, as was my wont, I was perusing the topics posted at Science Daily News, when this captured my attention: June 14th, 2018: New Type of Photosynthesis Discovered. And there it was. My speculations had been confirmed! Sort of. The lead researcher was Professor Bill Rutherford, Imperial College, England. “The standard, near-universal type of photosynthesis uses the green pigment, chlorophyll-a, both to collect light and use its energy to make useful biochemicals and oxygen. The way chlorophyll-a absorbs light means only the energy from red light can be used for photosynthesis. Since chlorophyll-a is present in all plants, algae and cyanobacteria that we know of, it was considered that the energy of red light set the 'red limit' for photosynthesis; that is, the minimum amount of energy needed to do the demanding chemistry that produces oxygen. The red limit is used in astrobiology to judge whether complex life could have evolved on planets in other solar systems. However, when some cyanobacteria are grown under near-infrared light, the standard chlorophyll-a-containing systems shut down and different systems containing a different kind of chlorophyll, chlorophyll-f, takes over. Until now, it was thought that chlorophyll-f just harvested the [red] light. The new research shows that instead chlorophyll-f plays the key role in photosynthesis under shaded conditions, using lower-energy infrared light to do the complex chemistry. This is photosynthesis 'beyond the red limit'. Lead researcher Professor Bill Rutherford, from the Department of Life Sciences at Imperial, said: "The new form of photosynthesis made us rethink what we thought was possible. It also changes how we understand the key events at the heart of standard photosynthesis. This is textbook changing stuff."

For me it was life changing. Bubbling over with excitement, I shared the news with whoever couldn’t get away. John Foushee, owner of Big Bloomers Flower Farm (BBFF) where I worked at the time, was one of my victims. John listened to my story then said with a wry smile, “You should be awarded the Nobel Peace Prize, Mike.” Laughing at my own stupid vanity I replied “Nah, maybe the Nobel Plant Prize.” I must admit, however, all this time later, I still find it very exciting. As Professor Rutherford stated, this has implications for the way we contemplate life on our planet and the possibility of life at distant places of the universe. Our perspective, understanding, and imagination have been broadened. Science requires an open mind – and inspires it too.

08 March 2022 UNDERGROUND LICHENS Lichens are fungi that have a symbiotic relationship with an algae that is incorporated within the tissue of the fungus. The symbiotic algae is called the lichen's "photobiont". Some lichens have Bluegreen algae as photobionts. So, based on the knowledge that some Bluegreen algae can use infrared wavelengths of the electromagnetic spectrum for photosynthesis, it is possible that there are lichens that live underground or at least out of direct sunlight, their photobiont using heat for photosynthesis. Yes, there are probably underground lichens.

LIFE'S FLUID DYNAMIC INTERCONNECTIONS

LIFE’S FLUID, DYNAMIC, INTERCONNECTIONS
Michael J. Papay, 01 January 2021.

Life is a flowing continuous thing while it lives.
It is ever interesting and beguiling.

Figure 1 provides a very simple, idealized, static depiction of interconnectedness between hypothetical species A, B, C and Z, given as a vertical cross-section through two 3-dimensional bells connected at their bases. The reality of the interconnectedness of living things is more complex than that. It is actually 4-dimensional. However, let us proceed in small steps.

NOTE: Due to formatting of Journal entries in iNaturalist, I had to use dots (periods) as space-fillers in Figure 1 and Figure 2.


Figure 1. Two-dimension, normal, bell-shaped distribution curves depict hypothetical species A, B, C, and Z. Only the distribution curves of species A and B are shown. The tails of the distribution curves of species A and species B flow into the beginning tails of distribution curves for species C and Z.

“Iconic A” represents what we would perceive as the archetypal representation of that species. With only a single glance you would declare, “That is species A”.

“Introgression” represents individuals whose traits are not specifically what we would tend to think of being obviously one species, or the other. However, individuals of the zones of introgression are exceedingly important in the continued procession of life into the dimension of time (the fourth dimension), for they are the substance of adaptation.

If instead of a view of a vertical cross-section of the two interconnected bells, let us consider an aerial view. See Figure 2.

I apologize for the non-circular outline of the two “normal” distributions depicted in Figure 2. My artistic skills with mere letters as a medium are not as impressive as one might hope.

What we would perceive as individuals with iconic traits of species A are found in the core of the somewhat circular distribution. The same is true for iconic individuals of species B. However, with this aerial view we see that the numbers of non-iconic individuals of either species is vastly larger than we tend to think. And it is here, at the margins of overlap and introgression, that nature provides novel forms. And this supply of novel forms might be imagined as probing the environment for new opportunities. This action becomes even more dynamic when the dimension of time is applied to the image. Each new generation provides new variation, however subtle it may be.

If the static image depicted in Figure 2 was imagined to be just a single frame in a motion picture, the playing of the motion picture forward, or backward, would show the distributional blob of each species pulsing and probing like an amoeba, or like a Slime Mold, and interacting with other taxa within reach. And the reach may be very far indeed, if one considers the various manners of pollination, and of seed dispersal. That is why life is a flowing continuous thing while it lives, and is ever interesting and beguiling. And it is why the methods of statistics are applicable and necessary in the study of taxonomy.

STATISTICAL PARAMETERS FOR SPECIES: The dynamic nature of life’s fluidity does not defy scientific description. Taxonomy can use the mathematics of statistics for molecular, morphological, behavioral data (et cetera) of species. The “type” of a species would be the datasets and their statistical means, variances, and distribution patterns resultant from detailed scientific studies. Drawings, photos et cetera should accompany the reports to clarify in illustration what the datasets represent.

Via statistical analyses, species (taxa) can be identified and compared mathematically. Too, the changes incurred over the passage of time could be documented in detail. This approach would direct the perception of a species from the narrowly described “Type individual” to the more comprehensive view of a range of variation about a statistical average, inclusive of variants and outliers. There would be consequent benefits to our understanding of the dynamic nature of life at every taxonomic level, accompanied by greater recognition of the importance of areas of connection/interaction

By defining taxa by their statistical averages, the eschelons of taxonomy will be stabilized.

As regards the application of statistics, there are times when the experienced mind must contemplate intervention. The odds of an event occurring may be slim, and the occurrence twice in separate taxa even rarer – that does not mean that such events are impossible. And when the encompassed picture in contemplation suddenly resolves into focus when the improbable is accepted as possible, then learned minds must take heed.
