Sidalcea. MALTACE-E. 83 



An Old World genus of about 20 species, some common in cultivation in gardens, and the fol- 

 lowing indigenous upon the coast of California. 



1. L. assurgentiflora, Kellogg. Shrubby, 6 to 15 feet high, with slender 

 flexuous branched, glabrous or sparingly stellate-pubescent : leaves cordate, angu- 

 larly 5 - 7-lobed, 3 to G inches broad, on long petioles, the lobes acute, coarsely 

 toothed or lobed : flowers 1 to 4 in the axils, on slender deflexed and curved pedi- 

 cels : involucel persistent, 3 lines long, half the length of the campannlate densely 

 pubescent calyx : petals purple, 1 to l. 1 , inches long, with a broad truncate limb and 

 long narrow glabrous claws, having a pair of dense hairy tufts at base : stainineal 

 column glabrous : styles exserted : fruit half an inch broad, the 6 to 8 carpels not 

 beaked, somewhat appressed-hairy, 2 lines or more in diameter, about equalling the 

 low-conical summit of the axis. — Proc. Calif. Acad. i. 11 & If. 



Said to be native of the island of Anacapa and now frequently cultivated in the southern coun- 

 ties of the State. It is nearly allied to L. accrifolia i pneenicea of the Canary Islands. 



L. OCCIDENTALIS, Watson, Proc. Am. Acad. xi. 121, of Guadalupe Island, Palmer, is a similar 

 species : flowers on short detlexed pedicels, with large and foliaceous bracelets and calyx-lobes, the 

 calyx becoming 1 h inches long : petals 2 inches long, spatulate, emarginate, purplish, with a dark 

 spot in the centre, the claws glabrous at base : fruit half an inch broad or more, pubescent. 



2. MALVA, Linn. Mallow. 



Involucel 3-leaved. Petals obcordate. Axis of the fruit broad but not project- 

 ing. Otherwise as Lavatera. — Natives of the Old "World, but several of the 

 species now naturalized almost everywhere. 



1. M. borealis, Wallnian. Annual, erect or somewhat decumbent, hairy or 

 nearly glabrous: leaves round-cordate, crenate, more or less strongly 5 — 7-lobed : 

 peduncles axillary, solitary or clustered, 1 to 3 lines long: calyx-lobes acute, be- 

 coming very broad and enlarged in fruit : petals 2 or 3 lines long : carpels trans- 

 versely reticulate-rugose. 



From Europe, a common weed on the western coast from Pugct Sound to Mexico : it has also 

 been collected in New Mexico. It is readily distinguished from the biennial species if. rot 

 folia, which takes its place in the Atlantic States and may appear in California, by its short 

 pcduntlcs, smaller flowers, and rugose carpels. 



3. SIDALCEA, Gray. 



Involucel none. Stainineal column double ; the filaments of the outer series 

 united usually into 5 sets, opposite the petals. Styles filiform, stigmatic on the 

 inner surface. Carpels 5 to 9, 1-ovuled, separating at maturity from the shorl axis, 

 beakless, indehiscent. Seed ascending. — Herbs, with rounded and mostly lobed or 

 parted leaves; the usually purple flowers in a narrow terminal raceme or spike. 



Mainly a Californian genus, only ono species of the Kocky Mountains (.S\ Candida, Gray) not 



being found within the limits of the State. 



* Perot ii in I. 



1. S. malvaefiora, I Iray. < '• labrous or somewhat hispid, simple or branched, 1 

 to 3 feet high : leaves on elongated petioles, orbicular to semicircular in outline ; the 

 lower more or less deeply toothed or cleft, the upper more narrowly and deeply 

 5 — 9-lobed or parted ; 1 1 1 « - segments sparingly toothed or divided, often linear and 

 entire: lowers in naked often elongated racemes; bractlets small, lanceolate; pedi- 

 cels short, naked: calyx often tomentose, the lobes acute or acuminate: petals 

 emarginate: carpels 7 to 8, smooth and glabrous. — PL Wright, i. 1 • ► : Watson,
