48 BOTANY. 



the "Wahsatch Mountains, and Bear Eiver Valley, Utah ; 4,500-6,000 feet 

 altitude ; June, July. (197.) 



Sph^ealcea^ Emoeti, 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-dentate, long petioled ; pe- 

 duncles 1-several-flowered ; upper flowers fascicled; capsule subglobose, 

 tomentose, 12-15-carpeled ; carpels mucronate. — This species also is quite 

 variable, and includes without doubt 8. Wrightii, Grray. 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 Frhnontii^ Torr., whose carpels are occasionally 

 2-seeded,) differing from S. incana chiefly in its larger flowers, fruit, and 

 calyx, the capsules more frequently mucronate above, and the fruit covered 

 with a denser stellate tomentum, which on boiling readily separates in mass. 

 S. incana., var. oUongifolia is S. Fendleri, Grray, and apparently nearly ap- 

 proaches S. 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 ; 6-6,000 feet alti- 

 tude; May-July. (198.) Some of the specimens accord with others which 

 are placed with Malvastrum Munroanum, in every respect except that the 

 carpels are 2-seeded. (199.) 



SiDALCEA. ACEEiFOLiA, Nutt. Scabrous with 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 |-li' 

 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 HEDEEACEA, Jorr. {Mal'va, Dougl.) Stellately pubescent; stem 



^ SFH/FiEALCEA, St. Hul. Characters nearly as iu MaVoastrwrn, but the carpels 2-ovuled, the 

 lower ovule ascending, the other pendulous, (often by abortion 1-seeded,) 2-valved, often truncate and 

 pointed above. Benth. & Hook.
