lection of 1862 seems to' connect it witli Var. serrulata. Mountains at the 

 head of Humboldt River ; 6,600-7,000 feet elevation. (568.) 



Var. PUBEEULA. (i. viscidiflora, Var. y., T. & G., in part.) Branchlets, 

 leaves, especially the lower surface, and outer involucral scales minutely 

 scabrous-pubescent; leaves narrow, 1-3-nerved.— California, and Western 

 Nevada (Bloomer) to the Rocky Mountains. Near the Truckee and on the 

 Hot Spring Mountains in Western Nevada, and in Bear River Canon, Uintas ; 

 4,500-8,000 feet elevation. (569.) 



LiNOSYEis HowAKDii, Parry. Proc. Amer. Acad., 6. 541. "Shrubby, 

 6-18' high; younger branches white-woolly; leaves linear, one-nerved, from 

 webby becoming smooth, the uppermost about as long as, or exceeding, 

 the corymbose and crowded heads ; involucre cylindrical, 5-flowered, the 

 scales rather loose, all of them finely acuminate ; tube of the pale-yellow 

 corolla sparingly villous; achenia linear, pubescent." G^ra?/.— Colorado, 

 (Parry.) Var. Nevadensis, Gray. Proc. Amer. Acad., 6. 541. "Leaves 

 rather wider and broader, the apex cuspidate and mostly incurved ; lower 

 ones sub-spatulate-linear ; involucral scales more webby, especially along the 

 margins, and somewhat viscid." Gray.— California, (Brewer,) and Western 

 Nevada, (Bloomer, Anderson.) West Humboldt Mountains; 8,000 feet 

 elevation; September. Plant a dense bush, about 2° high. (570.) 



Aplopappus^ Bloomeri, Gray. Proc. Amer. Acad., 6. 541. Shrubby, 

 about l°high; branches and leaves smooth; the latter narrow linear- 

 spatulafe, about 1' long and 2" broad, narrowed at the base, slightly apiculate, 

 1-nerved or indistinctly 3-nerved, the uppermost passing into the involucral 

 scales ; heads in dense sub-paniculate clusters ; involucres campianulate, 

 about 5'' long, the scales loosely imbricated in 3-5 series, lanceolate, rigidly 

 chartaceous with scarious cihated margins, and the outer ones with long- 



1 APLOPAPPUS, Cass. {Macxonema, Ericameria, Stenotus, Isopappus, Aplopappus, Pyrrocoma and 

 Prionopsis of Torrey and Gray's Flora.) Heads few-many-flowered; ray-flowors 3-mauy, pistillate, fertile ; 

 those of the disk tubular, perfect, generally fertile. Involucre cylindrical, turbinate, campanvilate or 

 hemispherical ; the scales imbricated in few-several series, from linear-subulate varying to broadly oval, 

 with or without foliaceous tips ; the outer ones sometimes smallest, sometimes very large and leaf-like. 

 Receptacle flat, alveolate. Corolla of the disk funnel-shaped, or slightly dilated upwards, 5-toothed. 

 Style of the disk-flowers with the branches flattened, sometimes broadly lanceolate, but more frequently 

 much elongated, the subulate hispid appendages much longer than the stigmatic portion. Achenia 

 oblong or linear, mostly terete or turbinate, villous or pubescent, rarely glabrous. Pappus simple, white 

 or brownish, of copious mostly unequal scabrous somewhat rigid or soft capillary bristles. — Perennial 

 herbs or suffruticose plants, with entire or plnnately toothed or serrate leaves ; the heads often large and 

 solitary, but sometimes smaller and corymbose or somewhat panioled. Native of Western North America 

 and parts of South America ; the flowers always yellow, but showing great diversity in the size of the 

 heads and in the rays, styles, pappus, etc. The few rayless species are not easily separated from Linosyris.
