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 ^-V long, confined to dry cliffs 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 ; J uly-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 S. 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.) 
Spir^a c^spitosa, Nutt. Shrubby, prostrate ; leaves rosulate on the 
very short matted branches, small, (2-6" long,) spatulate-oblong, entire, silky- 
villous ; flow^ering stems erect, 1-5' high, rarely branched, with small scat- 
tered leaves ; flowers in a dense cylindrical spike, w^hite ; 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.) 
Yar. 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 peculiar flavor ; flowers IJ' 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
