cate nearly naked, leaves scattered petiolate 

 lanceolate grossly serrate, flowers corymbose 

 pedunculate pappus fulvous — Apalachian Mts. 

 tall plant, leaves uncial. 



11. KuiixiA ciNEREA Raf. cincrcous 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- 

 hescens, 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 NEOPHYTON, 



12. Laxanon 203, although very near to Lap- 

 sana, Aposeris and Aptilon, it is quite distinct 

 from all ; Aposeris of Necker differs by calicu- 

 late perianthe ; my Aptilon which is the Apo- 

 gon of Elliot, this name being employed by La- 

 cepcde 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 am- 

 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 5partitc, few florets or ligules, 

 seeds ovate.
