Triplasis purpurea A. A. Reznicek

Sandy shores and low dunes; blowouts and cut banks inland. Old culms tend to disarticulate at the nodes into short segments (the internodes), each with a reduced fruiting inflorescence in the swollen sheath.

Depauperate or very young or old plants of this distinctive purplish annual, where the open panicles and decumbent branching are not evident, may resemble the small annual Sporobolus species, but are easily identified by their antrorsely bearded nodes.
