^ This only differs from B. barbata by being everywhere more hairy, the petioles are 

 densely shaggy as is the stem.— One example referred here of Griffith's has the stem 

 •nd petioles covered with a close brown tomentum without any spreading hairs, and 

 ^pears much more different from B. Thomsonii than is B. Tho7iisonii from B. 

 iarbata.

Appears to be a variety of B. barbata or B. Thonisonii with an abbreviated stem. 

 The capsules are not ripe but are very like unripe capsules of B, barbata. The leaves 

 are much less ciliate barbate on the margin than in B. barbata. But for the great 

 authority of Alph. DC, the three B. barbata, B. Thomsonii and B. Griffithii might 

 he united.
