long and broad; wings and keel whitish on the lower half, purple above. Wings 
oblong, auriculate, obtuse, the claw 7 mm. long, the blade 13 mm. long, about 5.5 mm.

Type in the U. S. National Herbarium, no. 305321, collected in a canyon in the 
vicinity of Tepic, Mexico, in flower, January, 1892, by Edward Palmer (no, 1997).

the largest flowers among the Middle American representatives of the genus.
