306 MALVACEAE. Sidalcea. 



— Idaho and interior of Oregon and Washington ; i first coll. by Nuttall. Also westward as 

 far as i'ortlaud, Oregon. 



S. glaucescens, Greene. Glabrous and smooth up to and even through the inflorescence 

 or an obscure pubescence on the pale or light green foliage : stems slender, a foot or two 

 high, simple or rather freely branching: leaves an inch or two in diameter; upper ones 

 5-7-parted into narrow divisions : racemes loose : petals about half inch long, sometimes 

 much smaller, not rarely white : fructiferous calyx about 3 lines long, from nearly glabrous 

 to cinereous-puberuleut, with lobes attenuate or acuminate from a broad base : mature carpels 

 relatively large, thin-walled, turgid, glabrous, coarsely reticulated, with the dorsal reticula- 

 tions mostly longer than broad, sometimes nearly smooth and even. — Bull. Calif. Acad. Sci. 

 i. 77. S. malvwjiora, Wats. Bot. King Exp. 46, in considerable part. — Higher Sierra Nevada, 

 California and Nevada, for most of its length, and east to Antelope Itland, Utah, Stanslmr,/, 

 Watson; the earliest collectors, Beckirilh and Anderson. Also Oregon (part of no. 71, 

 E. Hall) and near Victoria, Brit. Columbia, Fletcher ; pistillate plants, with bright green 

 foliage. Connects with the following subdivision. 



= = Mature carpels smooth and even, glabrous or nearly so. 

 a. Calyx large, 6 lines in length. 



S.* Henderson!, Watson. Tall and nearly glabrous: leaves large, deeply .5-7-cleft ; 

 sco-mcnts irregularly few-lobed or -toothed: flowers large in loose subsimple terminal 

 spkate raceme: i.racts linear, exceeding the short pedicels: calyx large, even in authesis 

 full half inch in length ; segments ovate, acuminate, purplish : petals, in dried state, deep 

 purple, about an inch in length : carpels few, 7 or 8, quite smooth, rather strongly beaked. 



— Proc. Am. Acad, xxiii. 262. — Oregon, near Clatsop Bay, Prof. L. F. Henderson, July, 

 1887, no. l'413 ; and (ace. to Piper) Washington, on beach near Seattle, and in brackish 

 marshes at the mouth of the Skohomish ; also on Vancouver Isl., near Victoria, Macoun 

 (no. 53. distr. as S. Oregana). A maritime species with the foliage of S. Oreijana but much 

 larger more deeply colored flowers. 



h. Flowers smaller : calyx 2| to 4 lines in length : not rarely with hirsute pubescence on 

 the stem and petioles and even on the calyx : upper cauline leaves mostly parted into 

 linear divisions or these again lobed. 



S. Neo-Mexicana, Gray. Stems a foot to a yard or even " 8 feet " high, the larger 

 branching or with paniculate loosely flowered racemes : lower pedicels as long as the (2 or 

 3 lines long) calyx. — PI. Fendl. 23, & Proc. Am. Acad. xxii. 287. S. mahceflora. Gray, PI. 

 Wright, i. 16, mainly (excl. syn.), ii. 20; Greene, Bull. Calif. Acad. Sci. i. 75.— Moist 

 ground, mountains of New Mexico and Arizona to those of Colorado; 2 first coll. by Fendlcr. 

 (Adj. Mex., Grajg.) 



S. spicata, Grekne. Stems a foot or two high, simple or sparingly branched : flowers in a 

 dense and oblong or sometimes looser and interrupted spike ; pedicels all much shorter than 

 the calyx or hardly any : calyx 3 or 4 lines long. — Bull. Calif. Acad. Sci. i. 76. Callirhoe 

 spicata, Hegel, Gartenfl. xxi. 291, t. 737, f. 3, 4, from cult, plant.' Also cult, as "Sidalcea 

 Murryana." — Sierra Nevada, California and adjacent Nevada, first coll. by Anderson, north 

 to Grant Pass,^ S. Oregon, Henderson. The looser-flowered form nearly approaches S. 

 Neo-Mexicana. 



* * Phalanges indistinct, most of the stamens separate, but the outermost combined merely 

 at base in threes or fours : scapose : leaves all pedately dissected. 



S. pedata, Gray. Sparsely or below copiously hirsute : scapes a foot or less high, ascend- 

 ingeroct from a short stock rising from a tuberous root, 1-2-leaved at base, naked above or 

 with a single small leaf : leaves all alike, pedately 5-7-parted or nearly divided and the 

 narrow cuneate divisions (barely inch long) 3-lobed or basal ones 2-lobed ; the lol)es 



1 This species extends southward to Napn Co., Calif., ace. to W. L. Jepson. The stipules in the 

 type are narrow and attenuate, but a noteworthy form, with shorter relatively broader stipules but 

 without other distinctions, has been found in Washington State by Piper and by Suksdorf. 



2 Northward to Wyoming, A. Nelson. 



8 And to Umpqua Valley, Oregon, Th. Howdl.
