somewhat purple-tinged flowers in a dense, elongated raceme. Raceme 
about 3 dm. long. Bracts triangular-]ance()latc, acute, 1.5-2 cm. long, 
about 4 mm. wide at base. Ovary very strongly winged, distantly

twisted wings of the ovary are very curious and quite distinctive of this species 
and E. cochleaia.
