With the help of more than 100 IUCN Species Survival Commission Specialist Groups, Global Wildlife Conservation has compiled the following list of lost species, spanning more than 160 countries, as part of the Search for Lost Species. We welcome additional nominations and encourage conservationists, scientists and naturalists to launch searches for species on this broad list.

Holothrix micrantha Schltr. (CR PE - last collected in 1925) - Southern Gauteng endemic

see my online posting of Cotula myriophylloides rediscovery - hence remove from list

well at least change its status from CR PE to CR, as reflected in current redlist. There are probably over 100 CFR plants not seen for a century or more....so lots to add in due course

Yes I once started a list of lost species (I think after someone from the organisation contacted me) but got overwhelmed very soon. For the Cape Peninsula alone we have a list of 30+ lost plant species! Today's Red Listing work included:
Rabiea comptonii Last seen 1923 (somewhere near Bloemfontein)
Euphorbia muraltioides Last seen 1904 (near Grahamstown)
Chrysocoma acicularis Last seen 1948 (south of Witteberg)
Selago persimilis Widespread across the eastern Karoo, but last seen in 1935

If someone wants to take on this project for SA plants it would probably keep you busy for quite a while!

But are they not all categorized as DDD or something like that? Is there an easy way of getting to the ones that you have done?

Publicado por tonyrebelo hace alrededor de 6 años

If it is suspected that they may be threatened, then they are listed as DD. Otherwise Rare or Least Concern. A lot of them are taxonomically problematic. I think a query on collection dates of occurrence records would probably be a good place to start, but you'll get a list of hundreds of species - to research all of them is a big job, one would need to narrow it down to a manageable task somehow.
