at each node of the elongated branches of the cymosely pan- 
leulate, ample inflorescence, forming a fascicle, which at length 
is frequently evolute into a proliferous branch. Tube of the per- 
onium a line and a half long above the abruptly enlarged 
fructiferous portion, very villous with long and spreading or im- 
plexed hairs; the limb 4 or 5 lines wide when fully expanded. 
Fruit (immature) two lines long.

most two lines long above the fructiferous base. Stigma pel- 
late, as in the genus generally.—Perhaps too closely related to 
B. scandens ; but the stem appears to ‘be truly upright, and 
~ Constricted tube of the perigonium is extremely short. The 
“pecies is dedicated to Col. J. D. Graham, under whose auspices 
the specimens were collected. Some of the flowers fructify pre- 
*etiously, as in so many Nyctaginaceee.
