Milkweed Flower Morphology

Plants in the subfamily Asclepiadoideae all have a very interesting morphology. One particularly interesting modification is that the staminate and pistillate parts are fused together into a structure called a gynostegium. The stamens have been modified so that the pollen sticks together to form pollinia. Members of the Genus Asclepias (and some other genera) have a very specialized corona that forms structures called hoods and horns. This morphology is explained in the below longitudinal section.

This is what it looks like normally.

Such valuable journal entries. Thanks for putting these informative things together, Nathan! It reminds me of reading @gcwarbler’s blogs — when he worked at Balcones, he put together such great blog entries (and now does it with iNat).

Keep it up, Nathan — I really enjoy these entries.
