was an accient one of Thapsia, and I have as- 
certained 5 species, probably all deviations. 
801. Upopion pinnattjm 11. stem sobangular, 
leaves pinnate, 5 folioles ovatoblong sessile 
acute serrate, base truncate obliqual, terminal 
base acuminate; fertile flowers subsessile, seeds 
with very unequal wings. — Discovered 1823 in 
West Kentucky glades and since in several 
other places, Alleghanies & c, pedal, or bipedal, 
perennial like all the sp. folioles 1 or 2 inches 
long, terminal often larger. Flowers estival as 
in all. 
802. Upopion lobatxjm R. stem striate, 
leaves all trifoliate, lateral folioles subsessile 
obliqual ovate acute serrate more or less lobed 
outside, terminal foliole petiolate, cordate ovate 
often trilobed ; umbels multiflore, fertile and 
sterile flowers on short peduncles seeds elon- 
gate with narrow wings. — In Pennsylvania the 
Alleghanies, Virginia &c, 1-2 feet high, leaves 
sometimes very large, and curiously or various- 
ly lobed or cut, flowers copious sometimes all 
fertile, but seeds unequal in size.— A var. Ri- 
gida or perhaps peculiar sp. has stem and um- 
bels stiff angular canaliculate, folioles large all 
unequal obliqual ovate oblong unequaly serrate, 
lateral sessile, medial base truncate aurieulate 
on one side. 
803. Upopion trifoliatxtm R. stem angular 
striate, leaves all trifoliate, radical on very long 
petiols, folioles ovatoblong serrate, lateral obli- 
qual, terminal on a long petiol, base rounded or 
truncate ; none lobed ; umbels pauciflore, flow- 
ers shortly pefluncled.— The most common sp. 
from New Jersey to Kentucky, bipedal, petiols 
often pedal, folioles uncial, the middle one some- 
times deltoid.
