Corycium bicolor.

This genus is very distinct from the rest of its cocoordinates, in having a 4-parted corolla. The insertion of the label near the top of the column & of the 2 small winglike leaflets hanging down at its sides at the back of the anther, afford the appearance of an inverted flower. The wings or leaflets the interior segments of the corolla.
