140 BOTANY. 



and slightly spreading, inner ones appressed, chartaceous with greenish tips. — 

 Plains of the Snake River, (Nuttall.) Valleys of Nevada and Northwestern 

 Utah ; 4,500-6,000 feet elevation ; June-October. Very near the next' but 

 it may generally be distinguished by its more slender habit and very narrow 

 leaves. (498.) 



AsTEE PALCATUS, Lindl. Stems minutely pubescent with appressed 

 hairs, 1-1 J° high, leafy to the top ; leaves rigid, minutely appressed-pubes- 

 cent, or smoothish except on the edges ; the lower ones spatulate-lanceolate, 

 often obtuse, 2-3/ long, 4-6" wide, short-stalked ; the upper ones oblong- 

 linear, sessile, often slightly clasping, those on the mostly erect branches 

 linear, but never subulate ; heads terminal on the branchlets ; involucre flat- 

 tened-hemispherical, 4-5" wide on the fresh plant ; scales much imbricated, 

 the outer smaller, all with greenish appressed or slightly spreading acute tips 

 and whitish chartaceous margins ; achenia pubescent. — This species must in- 

 clude A. cmnpestris and A. ramulosus of NuttaU. Arctic America to Oregon, 

 California, Nevada (Anderson) and Wyoming. Virginia Mountains and in 

 the Wahsatch ; 6,000 feet elevation; July-October (499.) A form with 

 wider leaves, slightly larger heads, and a harsher pubescence was collected 

 on the Truckee Eiver and in the "West Humboldt Mountains, (500,) and a 

 still larger and much branched plant, with something the habit of ^. oblongi- 

 folius, at Brigham City, Utah. (501.) 



AsTEE Bloomeei, Grray. Proc. Amer. Acad., 6. 539. Low, somewhat 

 tufted and spreading; branches 4-8' long, leafy; leaves small, 3-6" long, 

 oblong-linear or the lowest linear-spatulate, sessile, 1 -nerved, hispidly scab- 

 rous and ciliolate; heads terminal, single; involucre hemispherical, 3-4" 

 wide ; the scales loosely imbricated in about 3 series, linear-lanceolate, herba- 

 ceous along the midvein and at the apex, minutely glandular ; rays pale pur- 

 plish; achenia pubescent. — A small, irregularly growing species, with rigid 

 assurgent and branching stems and very scabrous foliage, referred by Dr. 

 Gray, though with some hesitation, to the Ericoidei. On Mt. Davidson, Ne- 

 vada, (H. Gr. Bloomer.) 



AsTEE SIMPLEX, WiUd. Common in the Atlantic States ; Canada, Wis- 

 consin, and Cahfornia, (Brewer.) To this species is referred a plant 1^° 

 high, densely brancheti above ; leaves scabrous-ciliate on the margins, nearly 

 entire ; the larger ones linear-lanceolate, 2-3' long, 3-4" wide ; upper ones 

 oblong-linear, slightly clasping ; heads very numerous, in dense terminal co-
