BOTANY. 
tlie Walisatch Mountains, and Bear River Valley, Utah ; 4,500-6,000 feet 
altitude ; June, July. (197.) 
Sph^ralcea^ Emoeyi, Torr Plant. Wright. 1. 21. More or less hoary 
or fulvous-tomentose ; stems several, from a woody base, usually simple, long 
racemed at summit ; leaves cordate at base, suborbicular, triangular or sub- 
hastate, more or less deeply 3-5-lobed, crenate-dcntate, long petioled ; pe- 
duncles 1-sevcral-flowered ; upper flowers fascicled ; capsule subglobose, 
tomcntose, 12-15-carpeled ; carpels mucronate. — This species also is quite 
variable, and includes without doubt S, Wiightii, Gray. It is so frequently 
the case that the carpels are 1-seeded, without trace of the upper ovule, that 
it is sometimes difficult to distinguish this species from the last. It may, 
indeed, be doubted whether they are not one It is intermediate between 
S. incana and S. Lindheimeri^ (which latter probably includes as a very 
tomentose form Malvastrum Fremontii, Torr., whose carpels arc occasionally 
2-seeded,) differing from 8. incana chiefly in its larger flowers, fruit, and 
calyx, tJie capsules more frequently mucronate above, and the fruit covered 
with a denser stellate tomentum, which on boiling readily separates in mass. 
S. incana^ var. ohlongifolia is 8. Fendleri, Gray, and apparently nearly ap- 
proaches iS. angustifolia^ Benth. The limits of these species are yet to be 
accurately defined. Reported previously from Northern Mexico, New Mex- 
ico, and Arizona, and not rare in the valleys of Nevada ; 5— G,000 feet alti- 
tude ; May- July. (198.) Some of the specimens accord with others which 
are placed with Malvastrum Munroanwn, in every respect except that the 
carpels are 2-seeded. (199.) 
SiDALCEA ACERiFOLiA, Nutt. Scabrous witli a stellate pubescence ; leaves 
cordate, deeply 5-7-lobed ; lobes acute, coarsely serrate ; racemes leafy below, 
naked above, the flowers clustered on short peduncles ; carpels 12-14, point- 
less. — Stem 3-6° high, much branched ; leaves 2-6' in diameter ; petals f-l^' 
in length, light purple or nearly white ; carpels pilose, dehiscent on the back. 
On the Columbia and its tributaries, from the Rocky Mountains to the ocean. 
Found in the East Humboldt Mountains, Nevada, and in the Wahsatch ; 
6-8,000 feet altitude ; June-September. (200.) 
SiDA HEDERACEA, Torr. (3falva, Dougl.) Stellatcly pubescent ; stem 
iSriLEKALCEA, St. Hill. Cliaractcrs nearly us in Malvastrum, but tho carpels 2-oviiled, tlio 
lower ovvilo ascending, tlio other pendulous, (often by abortion 1-seeded,) 2-valved, ofte'n truncate and 
pointed above. Bkmh. A; H(i«>k.
