For any of the curators who have been working on Euphorbia, Euphorbia PBI has a data portal where essentially all the species have been assigned subgeneric classification (under description). I've been working through the majority of the species as I find them and should have gotten all the North American species that have been added so far and have been slowly working through others. All this to say, there is a single source where the information can be referenced if you are interested.

Euphorbia incerta

var.

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.
