2. MALVA, Linn. Mallow. 

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

 ing. Otlierwise as Lavafera. — Natives of the Old World, but several of the 

 species now naturalized almost everywhere. 



1. M. borealis, "Wallman. Annual, erect or somewhat decumbent, iiairy or 

 nearly glabrous : leaves round-cordate, crenato, 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, ,i common weed on the western coa.st from Puget Soujid to Mexico ; it ha.s also 

 been collected in New Mexico. It is readily distingiushed from the triennial species M. rolundi- 

 folia, which tikes its jdace in the Atlantic States and may appear in California, by its short 

 l)edunclcs, smaller flowers, and rugose carpels. 



3. SIDALCEA, Oray. 



Involucel none. Htanuneal column double ; the fdaments of the outer series 

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

 inner surface. Carpels 5 to 9, 1-ovuled, separating at maturity from the short 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 Califoniian genus, only one species of the Rocky Mountains (5. Candida, Gray) not 



being fimiid within the Vmiits of the State. 



'!• Perennial. 



1. S. malvaeflora, Gray. Glabrous or somewhat hispid, simple or bi-aTiched, 1 

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

 lower more or less deeply toothed or cleft, the upi)er more narrowly and deejily 

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

 ontirn : llowers in naked often elongated niceme.s ; bractlet.M huihII, lanc(>olal(< ; pedi- 

 cels short, nakcil : calyx oftcui tom(Mitos(*, the lobes aculi« or acuminat(< : petals 

 enmrginato : carjiels 7 to 8, smooth and glahi-ous. — PI. "Wright, i. IG; Watson,
