Chamaesyce capitellata

A variable species, recognizable in part by its cyathia being born in dense cymose clusters. Typically, the plant has toothed, red-spotted leaves, and both stems and herbage with appressed pubescence, but there are entire-leaved, unspotted, glabrous forms; these traits may appear even on branches of otherwise typical plants.
