stout horizontal roots: herbage pubescent with long brown or 

 whitish shaggy hairs : leaves oblanceolate or ligulate, obtuse ; the 

 lower 10 cm. or less long by 10 to 15 mm. wide, tapering to broad- 

 ly margined petioles; the upper ones somewhat smaller, sessile: 

 panicle rather close: involucre 6 or 7 mm. high; its bracts nar- 

 rowly lanceolate, acute : ligules bright yellow : pappus fuscous. 



Always among rocks or in decomposed granite : Upper Tran- 

 sition and Canadian zones (altitude 1800 to 2500 m.) in the San 

 Jacinto and San Bernardino Mts., and on Mt. Pinos, Ventura Co. ; 

 to be expected in the San Gabriel Range ; northward throughout 

 the Sierra Nevadas. In Sierran specimens the color of the crin- 

 ite pubescence runs through all shades from rich reddish-brown 

 to pure white. 



3. H. Parishii Gray, Proc. Am. Acad. xix. 67 (1883). 



Plant 3 to 6 dm. high, stems several, apparently from stout 

 horizontal rootstocks, leafy up into the narrowly oblong panicle : 

 pubescence shaggy-hirsute on lower leaves and basal portion of 

 stem, glandular hairs of the inflorescence light-colored or none: 

 lower leaves oblong to narrowly lanceolate, tapering to margined 

 petioles, remotely but saliently toothed on the margins, 8 to 20 

 cm. long, 12 mm. or more wide ; upper ones narrow, sessile and 

 entire, 5 cm. or more long : peduncles shorter than or slightly ex- 

 ceeding the heads : involucral bracts linear-subulate : flowers yel- 

 low : pappus nearly white. , 



Foothills of the San Bernardino and San Gabriel Mts. in the 

 Upper Sonoran Zone. 



Dr. Gray describes this species as having ' ' no glandular hairs 

 or stipitate glands : * * * : involucre pale, granulose-puber- 

 ulent." Mr. Parish has collected it a number of times and 

 writes: "All specimens collected by me came from a limited 

 space on some cliffs at about 3000 ft. alt. in Waterman Canon." 

 Now, while these specimens are mostly only viscid-glandular in 

 the inflorescence, some of them have conspicuous but light- 

 colored stipitate glands, thus exhibiting an interesting variation 

 in this character. Mr. Parish further writes that the species 

 must have been founded on his no. 1132, of Sept. 25, 1881, this 

 being the only number of it collected previous to the publication 

 of the species.
