base of scape: pods many (8-12), scarcely compressed or flattened, 
ovate, stellately pubescent, 2-5 mm. long: style slender, i mm. or 
more long: seeds not winged. 
This plant is most closely related to D. argyrea and in leaf char- 
acters it is practically identical. It is distinguished from that species 
by the small, subspherical pods and the peculiar inflorescence which 
develops from near the base of the scape. D. sphaerocarpa was col- 
lected at a much lower elevation than were the specimens referred to 
D. argyrea.
