This species differs from O. cyanoides, Triana, by its smaller fruits, and from O. parvi- 
flora, Merrill, by the entirely different bracts. Leaves at the base cuneate or rounded. 
Bracts obovate, semiamplexicaul. Flowers pink (Kloss), smaller than in O. cyanoides, 
Triana. This latter species and also O. bracteata, Korth., have been recorded for New
