CATALOGUE. 81 



tures scarcely mucronate, lighter colored^and sericeous beneath, smoother 

 or nearly glabrous above ; flowers numerous, in more or less branched ter- 

 minal panicles, branches and calyx tomentose-pubescent ; calyx-segments 

 ovate, spreading ; carpels very hirsute. — A low branching shrub, 2-3° high, 

 with small leaves ^-1' long, confined to dry cliflfs and mountain-sides. 

 Rocky Mountains of New Mexico, Colorado and Wyoming, west to CaHfor- 

 nia (Brewer) and Oregon, (Geyer.) Throughout Nevada and Utah ; 5-10,000 

 feet altitude ; July-September. It takes the place in the mountains eastward 

 of the much taller and larger-leaved S. aricefolia of the valleys of Oregon and 

 California, upon which Pursh probably founded his 8. discolor. His speci- 

 mens, however, were from nearly the same region as Geyer's, and may belong 

 to this species, in which case his name has the precedence. (305.) 



Spie^a c^spitosa, Nutt. Shrubby, prostrate ; leaves rosulate on the 

 very short matted branches, small, (2-6" long,) spatulate-oblong, entire, silky- 

 villous ; flowering stems erect, 1-5' high, rarely branched, with small scat- 

 tered leaves ; flowers in a dense cylindrical spike, white ; carpels 3-5, dis- 

 tinct. — Growing upon limestone cliffs, the stems hugging the rocks, and 

 forming dense green mats, the branchlets beneath compacted with persistent 

 dead leaves of previous years. The stems attain considerable size, sometimes 

 an inch or more in diameter at base, but the absence of annual rings prevents 

 a determination of their age. Collected in Chihuahua, New Mexico, and 

 Northern Arizona, at the sources of the Platte, and at Crater Pass in the Cas- 

 cade Mountains, Oregon, (Newberry.) In the East and West Humboldt 

 Mountains, Nevada ; 6-9,000 feet altitude ; August-October. (306.) 



Var. ELATiOR. Flowering stems taller, (6-10',) branched, the lateral 

 spikes short ; leaves an inch or more long ; flowers somewhat variable ; petals 

 orbicular to linear-spatulate, smooth or hairy within ; ovaries as many as the 

 lobes of the calyx, (5-8,) very hairy or nearly smooth. — Found at the eastern 

 end of the Raft River Mountains, Utah ; 7,000 feet altitude. (307.) 



RuBUS NuTKANUS, M09. Stems 2-3° high, with the large leaves (4-6' 

 in diameter) nearly glabrous ; fruit rather large but thin, light red, with an 

 agreeable pecuHar flavor ; flowers 1 J' in diameter. From Southern Alaska 

 to Northern California and to the eastern slope of the Rocky Mountains and 

 Colorado ; New Mexico, (Fendler ;) and shores of Lake Superior. In the
