Chamaesyce hyssopifolia

A weedy plant similar to Chamaesyce nutans but with glabrous stems. Unfortunately there seems to be a fair amount of variation in stem pubescence in the hyssopifolia/nutans/vermiculata group of Chamaesyce and it is unclear exactly where lines between these taxa are drawn. I'm interpreting Chamaesyce hyssopifolia to include only the completely glabrous-stemmed forms, though some floras suggest that the species may be "inconspicuously" hairy.
