expanded ovate-lanceolate to elliptic in outline, about 1 cm. 
long, lightly 3-lobed beyond the middle; basal part obovate, 
about 6 mm. long, 4-4.3 mm. wide, traversed in the middle 
by a broad stout evanescent callus; anterior part oblong- 
quadrate to oblong-ovate, 3.8-4.9 mm. long, about 3 mm. 
wide, broadly rounded at the apex, carinate-mucronate near

larger flowers and dissimilar petals.
