cence, wliick becomes dense on the pedicels and calyx: 

 stems slightly decumbent at the very base, otherwise strict, 

 2 — 3 feet high, simple: lower leaves orbicular, about 9-lobed, 

 the lobes cuneate-obovate, 3-cleft at the apex; the middle and 

 upper 7 — 9-parted, their segments with 3 — 5 linear, some- 

 what spreading lobes: racemes short: petals emarginate, an 

 inch long, deep lilac-purple: calyx -lobes ovate, long acumi- 

 nate: carpels not seen. 



The specimens are from Mr. T. J. Howell of Oregon, and 

 the plant is reported to inhabit dry prairies. Mr. Howell's 

 printed labels bear the name, ''Sidalcea humilis, Gray"; but 

 this is a most distinct species, not so much like S. humilis as 

 S. spicata, from which latter species it is easily distinguish- 

 ed by its forked and retrorse, bristly hairs, abundant stellate 

 pubescence, and large flowers in racemes which are not at 

 all spicate-crowded. It is probably the Sida malvceflora, in 

 part at least, of Hooker, El. Bor. Am. and of Torrey & Gray, 

 Fl. N. Am. 



S. Oregana, Cray. 



Sparingly hirsute below, inflorescence stellate-tomentose, 

 other parts of the plant glabrous: stems 1 — 5 feet high, pan- 

 iculately branched above : foliage as in the preceding, but 

 the segments narrower: calyx globose in fruit, its segments 

 ovate to lanceolate, acute: corolla a half inch or more long: 

 carpels very small for the genus, smooth and glabrous, not 

 in the least depressed. — Sida Oregana, Nutt. Torr. & Gray

 S. malvceflora, in part, of Bot. Cal. I. 83. 



Very common in Oregon and the northern parts of Cali- 

 fornia. The largest species, distinguished by its paniculately 

 branching habit, and small calyx and carpels, the latter very 

 straight, not depressed as in the other species.
