 nate at apex, reticulated, smooth and shining above, the sparse pilose 

 pubescence beneath especially noticable on the midvein, profusely 

 punctate when fresh ; flowering spikes to 2-4 inches long, dense, thick, 

 calyx campanulate, glandular, pubescent, the teeth densely so with short 

 white hairs ; flowers rather large, twice the length of the calyx, deep 

 purple, stamens much exserted ; pod short, more than half enclosed in 

 the calyx, obovate, rounded on the ventral side, almost straight on the
