bb MALVACE^l. 



4. SIDA, Linn. Herbs with undivided leaves. Involucel (except 

 in ours where it is 3-bracteate as in the preceding). Calyx 5-cleft. 

 Stamineal tube simple. Stigmas capitate. Carpels 1-celled, 1-seeded, 

 dehiscent or indehiscent, forming a short conical fruit. Seed pendulous. 



1. S. hederacea (Dougl.), Torr. Perennial, stoutish, erect-spreading 

 or prostrate, very leafy, % 1 ** high* hoary- or yellowish-tomentose 

 throughout: leaves short-petioled, about 1 in. long, reniform, very 

 oblique at base, plicate, serrate or crenate: fl. axillary, solitary or several, 

 the pedicels slender: calyx subtended by 1 or 2 slender bractlets; lobes 

 acuminate: corolla % in. long, cream color: fr. short conical, smooth, 

 glabrous; carpels 610, triangular, 1J lines long. A depressed hoary 

 weed, very common in low and subsaline clayey soils. 



5. MALYEOPSIS, Presl. Herbaceous or shrubby (ours mostly hoary- 

 tomentose shrubs), with usually angular foliage, and solitary or 

 racemose-panicled flowers. Calyx with an involucel of 1 3 bractlets, or 

 none. Stamineal tube simple; free filaments terminal and distinct. 

 Styles 5 or more; stigmas capitate. Carpels 1-seeded, bivalvate-dehiscent 

 or indehiscent. Seed ascending. 



1. M. Fremonti (Torr.). Suffrutescent, very stout, 2-3 ft. high, 

 densely ivhite-lomentose: leaves very thick, short-petioled, 13 in. long, 

 broadly ovate, cordate at base, slightly 3-lobed and crenate: fl. in short 

 axillary pedunculate racemose clusters: calyx ovate, y z in. long, only 

 the setaceous tips of its lobes visible amid the deep and dense white 

 tomentum, almost equalled by the 3 linear setaceous involucral bractlets : 

 corolla % in. long, rose- color: carpels thin, smooth, promptly dehiscent. 

 Mt. Diablo and southward. 



2. M. fasciculata (Nutt.), O. Ktze. Usually 6-8 ft. high, often 

 larger and arborescent, the main stem a few inches thick; bark smooth, 

 gray; branches long, wand-like, slender, racemose or amply racemose- 

 paniculate above, these and the lower face of the leaves canescently 

 short-tomentose: leaves angularly 5-lobed and coarsely toothed, 1% 3 

 in. long, and almost as broad: calyx-lobes triangular, as broad as long, 

 acute: corolla rose-purple, ^ in. long: carpels smooth, tomentose above, 

 promptly dehiscent: seed with a stellular-hairy minute reticulation. A 

 very handsome shrub or small tree, common in S. Calif., reaching Mt. 

 Diablo, according to Rattan. 



3. M. arcuata. Size and general habit of the last but stouter; 

 leaves half as large, obtuse and with inconspicous rounded lobes, very 

 strongly rugose-veiny and white-tomentose beneath: interruptedly spicate 

 flowering branches stout, strongly recurved, the flower-fascicles all on 

 one .side: corolla merely pinkish: carpels densely stellate^tomentose. 

 Eastern slopes of the Coast Range back of Belmont; wrongly referred 

 to M. marrubioides in the Flora Franciscana.
