COMPOSITE. 



232. Eeigesok acre, L. 233. Diplopappus ertcoides, Torr. and Gray. 234. 

 Erigeron mpositum, Purah. g:,l. E., a species wholly doubtful to me, with 

 deep purple or blue rays,— except in this respect the same as the white-rayed 

 specimens of Parry's No. 3, which I had confounded with those of E. uniflfc 

 ru?n,vrith. which it was mixed. I dare not now venture to describe it as new 

 species. 236. E. glabellum, var. pubescens, Hook. Bourgeau collected the 

 same form In the Rocky Mountains. 237. E. divergexs, Torr. and Gr. £33, 

 E. GKANDiPLORUM, Hook. , var. elatim, Gray, Enum. PI. Parry, No. 1 : a still 

 more luxuriant plant ; stems more than a foot high, leafy 'to the summit, 

 bearing two to four heads, with the same very woolly involucre. 243. E. um- 

 florum, L., both the same as Parry's No. 8, and large and tali forr~~,6 to 9 

 inches high, with light-colored long wool to the involucre, as in the foregoing. 

 ''Common in the high alpine region." 239. E. glabella, Nutt. ? Yax.moUe. 

 This is recorded as a common species at all heights. But I have never before 

 seen such a form, except one of Bourgeau's, the largest specimens distribu- 

 ted under "J?. mescem," and that has white rays. From the shape of the 

 leaves, and their size and abundance up to the summit of the stem, this 

 should rather be referred to E. mar rant hum ; but the pubescence is-st ;e for 

 that species. 240. E. glabellum, Nutt. Parry's No. 4 (collected again) is a 

 dwarfer form of the same, and belongs rather to glabellum than to E. macron- 

 thum. (241, 242. See below, under Aster. 243. See above.) 244. E. c^spito- 

 sum, Nutt. ; a strict form, near the var. gran<Vjb>nim, — of which E. canum, 

 way, PI. Fend I., is evidently a form. "Common on low mountains." 245. 



E. PUMiLUjf, Nutt. 246. E. Bellldiastrcm, Nutt. \ 



247. Solidago laxceolata, L. 242. S. nemoralis, L. ; a dwarf, subalpine 

 form, passing to & nana, Nutt. ££[. S. Missouribm , Nutt. ; a dwarf form. 

 250. S. Virga-u kea, L. ; two forms. 251. S. Virga-aurea, var. multi- 

 ratLata, Torr. and Gray. Dr. Parry collected one specimen of S. humilis 

 on Clear Cr< ek. 



2il. Aster salsugixosus, Richards. " Subalpine.'' This is also 403 of Dr. 

 Parry's separate collection. 242. A. glacials, Nutt. "In the high alpine 

 region." gjfc-A. adscehm ^Tlindl., var. eiiiatifol s, Torr. and Gray, 

 XT™* IS also 4lg of Parry,*) and the var. Fremontii, Torr. & Gray, F SuppL 

 pjo. Various forms of the last, "alpine and subalpine, in low grounds," the 

 larger ones ( me as Parry's 417) passing towards A. integrifol , Nutt., but 

 the involucre not manifestly^glandular. All the peculiar Asters of the 

 Rocky Mountains and westward require complete re-elaboration. 254. (also 

 3yL£ oi ' Parry,) A., near the smooth form of lkuoides, L., and probably a va- 

 riety of it, but with laxer and narrower f les to the involucre. The rays 

 are pinkish, as they sometimes are in the eastern plant. "In the mountains 

 at middle elevations." ' 



§■& Aplopawm ixuloldes, Torr. and Gray. Subalpine, in the South Park. 



-5b. A. (Broom) pvgm.eus, Gray, Enum., PL Parry, mixed with specimens 



01 an dly dwarf new species, which Dr. Lyall collected, in I860, on the 



ummits of the eastern side of the Cascade Mountains, at 7500 hundred feet 



above the sea. It should therefore be named A. LvALLi.f Both high alpine.
