 most common shrub on land from whicli saj>ebnisli has been burned 

 or otherwise cleared, and is subclimax to that abundant shrub.

Shrub probably rathei' low, with numerous short slender erect 

 bi'auches, the leafy stems g-ray-tomentose but not loosely or fioeeulently 

 so: leaves narrowly linear, 4 cm. or less long, mostly less than 1 mm. 

 wide, but occasionally up to 2 mm., 1-nerved, tomentulose : intior- 

 eseence compactly eymose, rounded, 2 to 5 cm. across: involucre 7 to 

 9 nnn. high; at least some of the bracts abruptly acute or cuspidate, 

 the outer ones more or less glandular-pubei-ulent : corolla 8 to 9 mm. 

 long; lobes lanceolate-linear, 1.7 to 2.5 mm. long. 



The distribution of this variety was originally stated by Greene to 

 be "In the Coast Range, from Humboldt County (California) south- 

 ward. "" ]iater, this same author stated it as "Kern and Santa Bar- 

 bara counties."^ This restriction in the adoi)ted range was perhaps 

 due to the fact that certain specimens from Hum])oldt and oth(M- 

 northern counties do not meet the recpiii-ements of the description as 

 well as those from further south. The cuspidate bracts and long 

 corolla-lobes, together with the habit (especially- the small compact 

 rounded inflorescence), are here taken as the most satisfactory char- 

 acters for the variety. Accepting this definition, we find fairly typical 

 collections from the dry inner north Coast Ranges and from the 

 southern Sierra Nevada and San Bernardino ^Moiuitains. North and 

 east of Trinity County it apparc^ntly passes into spirit/sKs, from wliich 

 it scarcely differs save in the more nearly glabrous and abruptly 

 l)ointed bi'acts. At its southei'innost stations it meets and perhaps 

 merges into bernardi)ii(s.
