298 MALVACEiE. Malva. 



M. moschAta, L. (Musk Mallow.) Pubescent with spreading mostly simple hairs : lower 

 (rarely all) leaves suborbicular, rather shallowly incised; middle and upper cauliue leaves 

 deeply 5-parted and the divisions palmately or pinnately parted into linear lobes : carpels in 

 fruit rounded on the back, very hairy. — Spec. ii. 690.1 — Waste-grounds and roadsides,' 

 near dwellings occasionally. (Nat. from Eu.) In Maine called Musk Rose. 



M. Alcea, L. Pubescence short and stellular: cauline leaves 5-parted into oblong or broadly 

 linear and barely incised divisions : flowers larger : carpels glabrous. — Spec. ii. 689. — 

 Roadsides in a few places, E. New England and Michigan, (Nat. from Eu.) 



* * Flowers fascicled in the axils of most of the leaves, surpassed by their long petioles : 

 leaves round-cordate or reniform and merely obtusely lobed : root annual or biennial. 



H— Flowers large and showy, Ij to 2 inches in diameter: bractlets rather broad, oblong or 

 ovate-lanceolate. 

 M. SYLVESTRis, L. 1. c. (HiGH Mallow.) Hairy: stem erect, a foot to a yard high: 

 leaves 5-7-lobed : flowers an inch or more in diameter, generally mauve- or reddish-purple : 

 carpels about 10, reticulate-rugose on the back and with angled edges, glabrous or short- 

 pubescent. — Roadsides, &c., escaped from cultivation in some places. (Nat. from Eu.) 



H— -1— Flowers smaller : bractlets narrower, lanceolate to oblong-linear. 



M.* verticillAta, L. 1. c. Erect subsimple or branching mostly smoothish annual with 

 large shallowly 5-7-lobed crenate leaves : flowers subsessile, purplish or nearly white : calyx 

 tending to close in fruit : carpels at maturity scarcely reticulated, the transverse ridges 

 starting at the edges not branched and not attaining the fine straight rarely obscure mid- 

 nerve. — A troublesome weed in gardens about Middlebury, Vt., Brainerd. (Adv. from 

 Asia, N. Afr.) 



M.* CKfsPA, L. (Syst. Nat. ed. 10, 1147), the Curled Mallow- of the gardens, near 

 which it is sometimes spontaneous, a species of uncertain nativity, is perhaps, as originally con- 

 ceived by Linnaius (Spec. ii. 689), merely a variety of the preceding, from which it differs 

 chiefly in the more finely crenulate and undulate leaf-margins. 



M. ROTUNDiFOLiA, L. (CoMMON Or DwARF Mallow.) Pubcsceut Or almost glabrous: 

 stems procumbent from a large and deep firm root : leaves rounded, slightly 5-7-lobed, 

 crenate: corolla barely half inch in diameter, surpassing the calyx, pale: carpels about 15, 

 puberulent and rounded but not reticulated on the back. — Spec. ii. 688 ; Gray, Gen. 111. 

 ii. t. 116. — A common weed, extending across the continent, especially abimdant in the 

 Atlantic States and northward; fl. spring to autumn. (Nat. from Eu.) 



M.* parviflora, L.2 Glabrous or sparsely hairy : stems erect or ascending from an annual 

 root : leaves somewhat angulate-lobed : pedicels short : calyx larger than in the preceding 

 or with broader lobes, widely spreading under the fruit : carpels glabrous, sharply and 

 transversely reticulate-rugose on the back, the margins of which are somewhat winged and 

 denticulate. — Diss. Dem. PL, Amoen. Acad. iii. 416; DC. Prodr. i. 433; Jacq. Hort. Vind. 

 t. 39; Greene, W. Am. Sci. iii. 155. M. borealis, Gray, PI. Fendl. 15, & Gen. 111. t. 116, f. 5, 

 6 ; Brew. & Wats. Bot. Calif, i. 83, at least in great part ; Coulter, Contrib. U. S. Nat. Herb, 

 i. 31, ii. 36 ; not Liljebl. M. rotundifolia {borealis), Fries, Novit. ed. 2, 218. M. ohtusa, Torr. 

 & Gray, Fl. i. 225. — Abundant on the Pacific Coast from Brit. Columbia to S. California 

 and Mexico, east to Texas ; also locally established in waste places in the Atlantic States. 

 (Nat. from Eu.?) Varying greatly in size, and under the most favorable circumstances, as 

 in S. California, attaining gigantic stature for an annual. 



M.* PUsfLLA, Smith. Similar in habit and foliage to the last preceding species : calyx-lobes 

 mostly closed over the fruit : pedicels usually somewhat longer, tending to be reflexed in 

 fruit : carpels dorsally rugose-reticulate, at first tomentulose, later nearly or quite glabrate ; 

 margins obscurely if at all denticulate, not at all winged. — Eng. Bot. t. 241. M. parviflora, 



1 The M. Alcea of Rand & Redfield's Fl. Mt. Desert is an exceptional form of M. moschata, with 

 none of the leaves deeply cleft. 



■^ Dr. Gray did not recognize the American occurrence of this species, which under the name 

 M- borealis was confused with the next.
