cate nearly naked, leaves scattered petiolate 
lanceolate grossly serrate, flowers corymbose 
pedunculate pappus fulvous — Apalachian Mts. 
tall plant, leaves uncial. 
11. Kuhn i a cxnerea Raf. cinereous pubes- 
cent, stem grooved corymbose above, leaves 
scattered sessile adpressed linear lanceolate en- 
tire ; flowers fasciculate pedunculate cinereous, 
pappus fulvescent — a fine sp. found by myself 
in the Cumberland or Wasioto Mts. of East 
Kentucky and Tennessee, blended with K. pu- 
bescens , but now well distinguished and separa- 
ted. Bipedal, leaves biuncial often falcate, 
branches multiflore, perianthe of flowers quite 
cinereous, floscules also, but not the pappus. 
II part— neopiiyton. 
12. Laxanon 203, although very near to Lap- 
sana, Aposeris and Aptilon, it is quite distinct 
from all ; Aposeris of Necker differs by calcu- 
late perianthe ; my Aptilon which is the Apo~ 
gon of Elliot, this name being employed by La- 
cepe de for a G. of fish, differs by perianthe in a 
double series and seeds striate as in Crenamon. 
These Genera will form a small group of the 
Glossanthes, with naked seeds Aposerides Raf. 
I have found in Coll. herb, a second sp. of Lax- 
anon from Arkanzas, deemed a doubtful plant 
near Krigia by Nuttal, I call it. 
Laxanon heterophylum Raf. stem flexuose 
ramose, radical leaves narrow remotely pinna- 
tifid, segments lanceolate acute, stem leaves ara- 
plexicaule, linear lanceol. acute, involucre bifo- 
liate unequal, umbels 2-5flore— Arkanzas, an- 
nual, 6 to 8 inches high, leaves 2 or 3 inches 
long, flowers on filiform erect pedicels, perian- 
the commonly 5partite, few florets or ligules, 
seeds ovate.
