212 Plants collected during a journey 



212. Erigeron pumilum, Nutt. gen. ii. p. 147. On the 

 Platte. 



213. Inula villosa, Nutt. gen. ii. p. 151. Spreng. tyst. 

 iii. p. 523. With the preceding ? 



214. I. graminifolia, (3. tenuifolia, sericeo-lanuginosa ; 

 foliis angusto-linearibus, nitidis ; caule paucifloro, squamis 

 involucri glabris. 



Obs. Leaves narrower than in I. argentea (a variety of 

 I. graminifolia). 



215. I. ? ericoides, caule inferne ramoso, ramulis elon- 

 gatis, subsimplicibus, unifloris ; foliis subulatis, imbricatis, 

 appressis, hispidis ciliatisque. 



Desc. Stem five or sis inches high, divided a short distance from tho 

 root into several slender ascending branches. Leaves 2-3 lines long, sub- 

 ulate, rigid, alternate, pungent, very hispid, strongly ciliate. Flowers 

 solitary at the extremity of the branches, erect, rather smaller than in J. 

 falcata. Calyx imbricate, hemispherical ; scales linear-lanceolate, acute, 

 loose, hispid. Rays about 10, ligulate, yellow ? florets of the disk 10-12. 

 Pappus double; the exterior minute, chaffy; interior pilose, scabrous. 

 Seed hairy. 



Hab. On the Canadian ? 



216. Aster biennis, Nutt. gen. ii. p. 155. On the 

 Missouri. 



217. A. paludosus, Ait. Purshfi. ii. p. 547. Nutt. gen. 

 ii. p. 155. On the Missouri. 



21S. Brachyris, n. sp. Nutt. Arkansa. 



219. Grindelia sqjjarrosa, Brown, lin. trans, xii. p. 

 102. Richardson app. p. 33. Donia squarrosa, Purshjl. ii. 

 p. 559. Nutt. gen. ii. p. 163. 



Obs. It appears that the genus Donia of R. Brown, is of 

 more recent date than the Grindelia of Willdenow, founded on 

 the same plants. Sprengel (syst. iii. p. 575) refers the D. 

 squarrosa to Gr. inuloides of Willdenow and Kunth. Is it 

 not, as Nuttall suspects, rather a variety of G. glutinosa ? 



220. Cineraria intecrifolia, Willd. sp. pi. iii. p. 2082 

 Pursh fl. ii. p. 528. On the Missouri.
