6-4 PROCEEDINGS OP THE ACADEMY OP 



COMPOSITE. 



232. Erigebon acke, L. 233. Diplopappus ertcoides, Torr. and Gray. 234. 

 Eeigerox compositum, Parsh. 235. 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. uniflo- 

 rum, with which it was mixed. I dare not now venture to describe it as anew 

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

 same form in the Rocky Mountains. 237. E. divergens, Torr. and Gr. 238. 

 E. grandiflorum, Hook., var. elatius, 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. vxi* 

 florum, L. , both the same as Parry's No. 8, and large and tall forms 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. glabellum, Nutt. ? var. molle. 

 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 " E. canescens," 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. macranthum ; but the pubescence is strange for 

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

 dwarfer form of the same, and belongs rather to glahellum than to E. macran- 

 thum. (241, 242. See below, under Aster. 243. See above.) 244. E. c.e>pito- 

 sum, Nutt. ; a strict form, near the var. grandiflorum,ot which E. caimm, 

 Gray, PL Fendl., is evidently a form. " Common on low mountains." 245. 

 E. pumilum, Nutt. 24G. E. Bellidiastrum, Nutt. 



247. Solidago lanceolata, L. 248. S. nemoralis, L. ; a dwarf, subalpine 

 form, passing to S. nana, Nutt. 249. S. Missouriensis, Nutt. ; a dwarf form. 

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

 radiata, Torr. and Gray. Dr. Parry collected one specimen of 5. humilis 

 on Clear Creek. 



241. As'ier salsugixosus, Richards. "Subalpine." This is also 403 of Dr. 

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

 region." 252. A. adscexdexs, Lindl., var. ciliatifolius, Torr. and Gray, 

 (which is also 419 of Parry,*) and the var. Fremontii, Torr. & Gray, Fl. Suppl. 

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

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

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

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

 418 of Parry,) A., near the smooth form of ericoides, L., and probably a va- 

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

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

 at middle elevations." 



255. Aplopappus inuloides, Torr. and Gray. Subalpine, in the South Park. 

 256. A. (Stenotus) pygWus, Gray, Enum., PI. Parry, mixed with specimens 

 of an equally dwarf new species, which Dr. Lyall collected, in 1860, on the 

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

 above the sea. It should therefore be named A. Lyalli.| Both high alpine. 



* Aster (Orthomeris) gi.aucus, Torr. and Gray, not in the general collection, is again in Parry's 

 sc iarate collection (No. 13). in the finest state. . 



A. Fendleri, Gray, PI. Fendl. (perhaps a hispid form of A. Xutlallii,) was sparingly collected on 

 sand hills, on the plains, but not distributed.
