OBSEEVATIONS ON THE COMPOSIT.I:.— V. 



By Edward L. Greene. 



[Pyrrocoma concluded, from p. 60.]. 



11. P. crocea. Aplopappiis croceus^ Gi'ay? Proc. Philad. 

 Acad. 65 (1863). Asier croceuSy O. Ktze. Eev. Gen, 317. 

 Middle Park, Colorado, and elsewhere in moist meadows at 

 great elevations. 



12. P. integrifolia. Aplopappiis integrifoliitSy Porter, 

 in Gray, 1. c. (1863), Asier Canhyi^ O. Ktze. 1. c. 315. — In 



similarly high and cold mountain meadows of Wyoming and 



Montana. 



13. P. lanceolata. Donia lanceolataj Hook. El. ii, 25 



(1834). Homopappus midiijiorus^ Nutt. Trans. Am. Phih 

 Soc- vii. 333 (1840). Aplopappus lanceolatus, Torr.& Gray, 

 Fl, ii, 241 (1842). Asier lanceolaius , O. Ktze. 1. c. 313.— 

 Common in moist plains throughout the Great Basin and 



■ 



northward. 



14 P. tennicaulis. Aplopappus ienuicaulis, D. C. 

 Eaton, Bot. Kiug Exp. 160: A, lanceolatus var. ienuicaulis, 

 Gray, Syn. FL 129.— Plentiful at the Humboldt Wells, 

 Nevada, and thoroughly distinct from P. laiiceolaia. The 

 two grow in the same localities, without intergrading. 



15. P. hirta. Aplopappus hiriiis. Gray, Syn. Fl. 127 

 (1884). Asier Gray amis, O. Ktze. 1. c. 316 (1891). Plant 

 with just the habit of P- lanceolata, with leaves quite as 

 exclusively radical, and stems scapiform; hence Asa Gray's 

 remark that it has the habit ol ''Aplopappus Whiineyi^' is 

 entirely unaccountable, for that is not only wholly destitute of 

 radical leaves, but has erect stems suflfrutescent at base, and 

 equably leafy up to the inflorescence. The involucres of the 

 two species, and these only, are much alike. In habit there 

 is not the least likeness between them. — Oregon and Wash- 

 ington. 



Erythea. Vol. II., No, 5. [1 May, 1894].
