Hieracium griseum. 

 Hieracium Scouleri Torr. «& Gray, Fl. N. Am. 2: 478, mainly 



[Syn. Fl. I-: 427, in part; Man. R. M. 217] ; not Hook. 



Stem 6-10 dm. high, covered with long white or yellowish hairs 

 from evident papillae ; leaves linear-oblanceolate or oblong-linear, 

 densely beset with long white hairs : panicle narrow, more or less 

 hairy ; heads about i cm. high ; bracts linear-lanceolate, moderately 

 imbricated, glandular, dark, and, at least when young, beset with long 

 hairs ; achenes dark brown, glabrous, striate ; pappus yellowish or 

 dirt}' white. 



Two specimens from Scouler's collection, constituting without 

 any doubt a part of the material from which H. Scouleri Hook, 

 was described, are in the Torrey herbarium, and these belong to a 

 species ver}^ distinct from what has generally gone under that name. 

 Scouler's plant has short obovate or spatulate rather numerous basal 

 leaves, rather few stem-leaves, longer brownish hairs, more open 

 panicle, and smaller heads which are 8 mm. long. It is apparently the 

 same as //. reclimwi Fries, Epicr. Hier. 153. Fries, following 

 Torrey and Gray, adopted the name H. Scouleri for H. griseum. 

 H. Vancouver ianum mentioned by Gray on page 428, and included in 

 H. albijlorum, belongs probably to H. Scouleri proper, at least as it is
