 pecially hispidly pilose, margin white, cartilaginous, conspicuously 

 undulate-dentate or almost entire. Peduncles dichotomous, long and 

 slender, furnished with small bracts. Calyx glabrous, tube twice as

 sile, ovate-lanceolate, narrowed at the base, about 2 in. long by 9 lines 

 broad, the upper ones acute, hispid along the midrib on the under
