168 NORTH AMERICAN FAUNA. [wo. 16. 
Senecio canus Hook. 
Common on the rock-strewn pumice slopes above timberline. (Identi- 
tied by Miss Eastwood and Professor Greene.) 
Solidago elongata Nutt. 
Abundant in open grassy places at Wagon Camp, where it was in 
flower in August and September. (Identified by Professor Greene.) 
Agoseris monticola Greene.’ Alpine Dandelion. 
Abundant in the neighborhood of timberline on the stony slopes and 
basins, where its yellow dandelion-like flowers were conspicuous from 
the end of July until the middle of September. On warm southerly 
slopes it was observed as high as 9,750 feet. Its wavy leaves are some- 
times entire, sometimes indented or cut. This species has just been 
described by Professor Greene from specimens collected by us at tim- 
berline on Shasta. 
Crepis intermedia Gray. 
Collected by Miss Wilkins in Mud Creek Canyon near the mouth of 
Clear Creek, where its zone position is either Hudsonian or Canadian. 
(Identified by F. V. Coville.) 
Hieracium albiflorum Hook. 
Common in places along the upper part of the Transition zone. Col- 
lected at Wagon Camp, on Squaw Creek, and on a warm slope in Mud 
Creek Canyon near the mouth of Clear Creek. (Identitied by Miss 
Jastwood and Professor Greene.) A dwarf alpine form, apparently not 
yet named, occurs above timberline and is fairly common above the 
head of Squaw Creek, growing with H. horridum, 
Hieracium cynoglossoides nudicaule Gray. 
Very common in the Transition zone just below Wagon Camp. 
(Identitied by Professor Greene.) 
Hieracium horridum Fries. 
Common in places on the higher slopes at and above timberline, 
forming small and densely hairy tufts among the rocks. The plant, 
particularly when young, is completely covered by a very dense growth 
of stiff silky white hairs which give it a woolly appearance. 
Hieracium gracile Hook. 
Common in the heather beds just below timberline, where its conspicu- 
ous yellow flowers were in blossom the early partot August. (Identified 
by Miss Eastwood and Professor Greene.) 
Hieracium greenei Gray. 
Fairly common just below Wagon Camp in the Transition zone. The 
type locality of this species is in the Scott Mountains a little west of 
Shasta. (Identified by Professor Greene.)
