Sidalcea. MALVACEAE. 303 



S. diploscypha, Gray. Soft-hirsute, and with some fine soft pubescence, a foot or two 

 high, with spreading branches and racemosely or corymbosely few-flowered peduncles : 

 leaves round-reniform in outline, earliest merely crenate, the rest 5-7-parted and divisions 

 mostly 2-3-lobed, lobes and divisions of lower leaves broadish, of upper linear, of the sessile 

 bracteal ones almost filiform: calyx-lobes lanceolate-subulate: petals inch long: carpels 

 beakless, depressed- or cochleate-reniform and more or less reticulate-rugose at maturity, 

 lightly sulcate down the back, at separation leaving behind on the receptacle as many subu- 

 late obtuse processes of nearly the height of the narrow central receptacle. — Gray in Benth.

Var. minor, Gray. Smaller, the corolla barely inch and a half in diameter, seemingly 

 deeper-colored and with a dark-purple centre : mature carpels more rugose and turgid. — 

 PI. Fendl. 19.' — Valley of the Sacramento, and Lake Co. ; the earliest collectors being />«'- 

 mo7it and Hartweg. 



S. hirsuta, Gray. Stem soft-hirsute, at least above, often glabrous below, strict or with 

 ascending branches, commonly 2 feet high, bearing numerous flowers in dense and rather 

 short racemes or spikes : cauline leaves palmately or pedately 7-9-parted or -divided into 

 narrowly linear and entire divisions ; lower glabrous ; bracts mostly small and inconspicu- 

 ous : calyx densely cinereous-pubescent and hirsute ; the lobes triangular-lanceolate : petals 

 inch or less long, light rose-color : carpels at maturity three fourths orbicular or subreniform, 

 reticulated on the back and sides, ventrally tipped with a soft and hairy erect at length de- 

 ciduous subulate beak, at separation leaving a scarious portion of insertion on the thickish 

 receptacle. — PI. Wright, i. 16 ; Torr. Pacif. R. Rep. iv. 72 ; Gray, Proc. Am. Acad. xxi. 410.

 wet but soon exsiccated grounds ; first coll. by Hartweg, then by Bigelow. 



•i— •*-- Carpels dorsally striate-reticulated with long meshes or several-ribbed. 



S.* Calycosa, M. E. Jones.'^ Like the foregoing, but with broader leaflets and smaller and 

 less copious flowers : stem pale green or stramineous, covered toward the summit with sparse 

 spreading pubescence : stipules ovate, acuminate, large, 3 lines in length, green : inflores- 

 cences terminal, spicate, short and dense : calyx-lobes ovate or ovate-lanceolate, acuminate 

 (3 or 4 lines long) : mature carpels reniform, striate-nervose on the rounded back, minutely 

 reticulated on the sides, the slender weak beak evanescent. — Am. Nat. xvii. 875; Gray, 

 Proc. Am. Acad, xxi 410. — Sonoma Co., on Russian River, M. E. Jones. 



S.* sulcata, Curran. More slender and branching : .stem mostly glabrous, purplish : leaf- 

 segments narrow : stipules very small, dark reddish, a line in length : inflorescence at length 

 loose : flowers rather small for the group and of deep color : calyx smaller and less inclined 

 to become scarious than in the la,st preceding species : petals reversed-deltoid, 6 or 8 lines in 

 length and breadth. — M. K. Curran in Greene, Bull. Calif. Acad. Sci. i. 79. Reduced to 

 S. calijcosa by Gray, Proc. Am. Acad. xxi. 410, Greene, Fl. Francis. 104, and E. G. Baker, 

 Jour. Bot. xxix. 51, but apparently distinct. — Central California, Eldorado Co., Mrs. Curran, 

 Mariposa Co., at White Rock, Congdon, and Marin Co., near Lagunitas Lake, Dr. Merrill. 



* * Exterior phalanges closely approximate to the interior at the summit of the column, 

 2-parted into narrow divisions, each 2-antheriferous ; interior phalanges less conspicuous ; 

 structure therefore similar to that of the ordinary perennial species. 



S. Hartwegi, Gray. Slender, paniculately branching, a foot or two high, minutely pubes- 

 cent : leaves sim])ly palmately or pedately 3-7-parted into linear divisions, or some of these 

 occasionally 2-3-lobed and broader : flowers few or several and rather loose in short racemes, 

 minutely bracteate : calyx-lobes lanceolate, attenuate-acuminate : petals half to three fourtlis 

 inch long, deep pink-purple : carpels at full maturity reniform-incurved (at first with basal
