NEOPHYTON. 35 



essee, annual estival, only 3 to 4 inches high- 

 leaves not ciliate, but the calix instead. 



278. IsANTHUS PUBESCENs Raf. quite pubes- 

 cent, stem branched, leaves sessile trinerve lan- 

 ceolate acute, peduncles biflore curved sub- 

 equal to leaves longer than calix— Mts. Wasi- 

 oto or Cumberland of East Kentucky, annual, 

 pedal. This is nearer to /. ceruleus of Mx. 

 my Is. ciliatus which has however leaves ovate 

 lanceolate ciliate, short peduncles and is nearly 

 viscid. 



279. IsANTHus MULTiFLORUs Raf smooth, 

 very branched, leaves sessile linear lanceolate 

 uninerve, peduncles multiflore, pedicels shorter 

 than calix — with the last in the Wasioto hills, 

 semipedal, annual. Thus this monotype Amer- 

 ican Genus is now increased by me to 4 spe- 

 cies ; they are all estival and commonly grow 

 in Limestone soils, I have perhaps another 

 doubtful from Texas, with obovate leaves. 



280. Parthenium hispidum Raf. stem flex- 

 uose sulcate hispid, hairs white, lower leaves 

 obovate base acute, the lowest on a long hispid 

 petiol, upper leaves sessile oblong and ovate, 

 base truncate, all acute with large unequal 

 teeth ciliolate, slightly hispid on both sides, 

 flowers corymbose glomerate sessile toment6se 

 pale fulvous — another sp. of this American 

 Genus, from the Glades of Arkanzas and Texas 

 humble, hardly over a foot high, with stiff white 

 hairs, only one radical petiolate leaf, few leaves 

 all different in size and shape, flowers fulvous 

 white, porianthe with ovate obtuse sepals. 



281. Triosteum connatum Raf perfoliatum 

 and majus of some hot — stem sulcate pubes- 

 cent, leaves connate ovate rhomboidal acumi- 

 nate undulate, rough above, tomentose beneath
