— Has n wide range, and runs into several varieties, of which the Vollowing occur 

 in California : — 



Var. glabrata, Gray, 1. c, with little Avoolliness, and tiiat deciduous, at least 

 from the leaves and involucre, or tho latter glabrous from the lirst. 



Var. hololeuca, Gray, 1. c. Clothed with a dense close coat of white wool : 

 scales of the involucre oblong linear and very obtuse, only tho innermost glabrous : 

 corolla with very short lobes, its tube beset with a few long and delicate cobweb- 

 like hairs. 



Var. albicaulis, Gray, 1. c. Like tho preceding variety in the white-woolliness, 

 or the leaves (becoming naked in age) and the narrower and less obtuse scales of 

 tho mvolucro slightly or not at all woolly : corolla with rather long lobes (tho 

 length double tho width), its tube beset with al)undant long and cobwebby hairs.

6 Gray, Fl. 1. c. 



In alkaline soil, on the eastern slope of the Sierra Nevada, from Mono Lake to Sierra Valley : 

 thence abundant through the interior to the borders of British (.^lumbia and the nlains east of 

 the Rocky Mountains. The var. Iwlokuca, Owens Vallev, Dr. Horn. Var. nlhtmulis above 

 JJonner Lake, at 10,000 feet, E. L. Greene, a rare form, anparcntly confined to a narrow district 

 m the interior, extending to the eastern part of Oregon and adjacent parts of Idaho. 



10. B. Douglasii, Gray, ]. c. Shrubby, from G inches to fi feet high, never 

 woolly, glabrous, or roughish with a minute harsh pubescence, fnstigiutely branched : 

 leaves varying from very narrowly to broadly linear or lanceolate, rather rigid (nn 

 inch or two long), tho broader ones 3-nerved : heads a (piarter to a third of an inch 

 long, mostly numerous in a close corymb or cyme, fi flowered : .<;caIos of the invo- 

 lucre oblong or oblongdinear, obtuse, rather firm, destitute of greenish tijis, rather 

 few in 4 or 5 vertical mnks : lobes of the corolla rather long, spreading : nkenes 

 rather short, silky-villous : stylo-appendages narrowly subidate, usually oidy half tho 

 length of the stigniatic portion. — Linosyris visriilijlora, Torr. it (Jray, witli tho syn. 

 Crinitaria viscidiflora, Hook. Fl. ii. 24, but the flowers not viscid, even the invo- 

 lucre rarely so. — I'esides the smooth and glabrous ordinary form, there are in Cali-
