Sida. MALVACE^. 321 



§ 3. Cleistanoda, Gray, 1. c. Seed (glabrous) completely and permanently 



invested by a lirm corrugate-reticulated or in age clathrate (doubtless endocar- 



pial) arilliform coat : otherwise as in § 2. 



A.* crenatiflora, Ort. Minutely puberuleut or glabrate, the calyx canescent : lower 

 leaves cordate aud augulate or somewhat lobed, upper mostly hastate : upper flowers naked- 

 racemose : petals yellow (or changing to purplish when drying) : carpels 9 or 10, short-beaked 

 or pointed, hirsute at the radiate summit, the permanent dorsal portion of firm texture or 

 below reduced to a stout and rigid midnerve. — Dec. viii. 96 ; Schlecht. LinniEa, xi. 217. 

 A. parvijiora, Cav. Ic. v. 19, t. 431 ; DC. I'rodr. i. 459; Keichenb. Ic. Bot. Exot. t. 44; 

 Gray, 1. c. Sida parvijiora, Willd. Enum. 726. — So near our S. W. boundary (Pringle, 

 &c.) that it is to be expected in Arizona. (Mex. ; Lower Calif., Brandegee.) 



A. reticulata, Watson. Herbage of preceding; but nearly all the leaves cordate angulate 

 and upper 3-5-lobed, small : flowers mainly naked-racemose : petals blue, 2 or 3 lines long : 

 fruit not radiate, hardly puberulent, of 10 oval carpels with rounded summit and not even 

 umbonate on the back, the permanent dorsal portion thin-membranaceous, delicately 1-nerved 

 below and veiny above, merely concave, at length nudating the arillate seed. — Proc. Am. 

 Acad. xvii. 368; Gray, 1. c. — S. Arizona, in the Santa Cataliua Mountains, Pr ingle, 1881. 



12. SIDA, L. (SiSt;, unexplained Greek name of some plant.) — Herbs 

 or sometimes undershrubs (most largely American and of warm regions), of 

 various habit : pedicels mostly articulated ; fl. summer and autumn, mostly open 

 only in sunshine or for a few hours. — Syst. Nat. ed. 1, & Gen. no. 556; St. 

 Hil. Fl. Bras. Merid. i. 173 ^ Gray, PI. Fendl. 22, & Gen. 111. ii. 61, t. 123; 

 Benth. & Hook. Gen. i. 203.^ 



§ 1. Pseudo-Malvastrum, Gray. Usually 2 or 3 slender and deciduous 

 bractlets under the more or less 5-angled calyx : flowers solitary or somewhat 

 clustered in the axils of the leaves : peduncles commonly recurved or deflexed in 

 fruit : low or depressed perennials, canescent with stellular and sometimes lepidote 

 pubescence, except in the fruit very like species of Malvastrum and Sphceralcea. 

 — PI. Fendl. 23. 



S. hederacea, Torr. Rather scurfy-canescent : stems decumbent : leaves obliquely sub- 

 reniform or ovate-subcordate, irregularly dentate (half inch to 2 inches wide) : calyx-lobes 

 ovate or ovate-lanceolate, short-acuminate : petals pale yellow or white or sometimes 

 " purple," barely half inch long, moderately surpassing the short-conical fruit of 6 to 10 

 turgid-ovate or triangular acutish tomentulose but glabrate carpels. — Torr. in Gray, PI. 

 Fendl. 23, PI. Wright, i. 18, & ii. 21 ; Wats. Bot. King Exp. 48 ; Brew. & Wats. Bot. Calif. 

 i. 86. S. obliqua, Nutt. in Torr. & Gray, Fl. i. 233, 681. Malva Californica, Presl, Rel. 

 Haenk. ii. 121. M. hederacea, Dougl. in Hook. Fl. Bor.-Am. i. 107 ; Torr. & Gray, Fl. i. 

 227. M. plicata, Nutt. 1. c. 227. — Low banks, Washington to S. California, Utah, Arizona, 

 and W. Texas. (Mex.-) 



S. lepidota, Gray. Throughout scurfy-lepidote, silvery when young : leaves obliquely 

 deltoid-subcordate or triangular-lanceolate and commonly semicordate or seniihastate, irregu- 

 larly or incisely dentate, mostly acute, quarter to inch and a half long, slender-petioled ; 

 lower i)eduncles usually elongated and in fruit deflexed with apex incurved : petals half inch 

 or more long, purple or white with purple tinge : calyx almost 5-parted, somewhat ampliate 



1 Add E. G. Baker, Jour. Bot. xxx. 138. 



2 Also Lower Calif., /f/e Brandegee, and Chili, /cZe E. G. Baker (Jour. Bot. xxx. 1.38), who regards 

 the S. American S. sulphurea, Gray, as a variety of S. hederacea. S. hederacea, var. V parvifolia, 

 IK-nisl. Biol. Cent.-Am. Bot. i. 104, never properly described, but vaguely credited to New Mexico, is 

 (as to the Mexican types cited) not of this species, being in pubescence much nearer S. lepidota, of 

 which it is probably only a depauperate round-leaved form.
