168 RANUNCULACEAE. 



rhombic-spatulate, concave dorsally; stamens 11 to 14 or 18; berries red or 

 white, with polished surface. — (A. spicata var. arguta Torr.) 



North slopes of brushy or wooded hills: Oakland Hills, Marin Co. and 

 northward near the coast. (Pistils sometimes 2 and partly united. — Berkeley, 

 1908.) 



6. CLEMATIS L. Virgin's Bower. 



Stems woody below, climbing by aid of the petioles of the opposite compound 

 leaves. Peduncles axillary, bearing 1 to numerous flowers. Flowers polygamo- 

 dioecious. Sepals 4, valvate in the bud, white and petal-like. Petals none. 

 Stamens numerous. Achenes numerous in a head-like cluster, the styles per- 

 sistent as hairy or plumose tails, very conspicuous in fruit. (Ancient name, 

 from Greek klema, a twig.) 



Peduncle bearing a panicle of many flowers; leaflets 5 to 7 l.C ligusticifolia. 



Peduncle 1 to 3-flowered; leaflets 3 2. C. lasiantha. 



1. C. ligusticifolia Nutt. Yerba de Chivato. Nearly glabrous, except the 

 inflorescence; leaflets 5 to 7, ovate, cordate or obtuse at base, 3-lobed or 

 coarsely toothed about midway, or nearly entire, mostly 1 to 3 in. long; 

 peduncles 1 to 4 in. long, bearing a panicle of many to numerous flowers; 

 flowers % to % in. in diameter. 



Valleys, foothills and mountains, climbing high over shrubs: Coast Eanges, 

 Sierra Nevada, Southern California. Sepals sometimes 5 (Napa Valley, 

 1901). An infusion of the herbage is valued by Spanish-Californians as a 

 remedy for cuts in horses made by barb-wire. 



2. C. lasiantha Nutt. Pipe-Stem. Branchlets and sepals tomentose-pubes- 

 cent, the foliage less so; leaves trifoliolate, the leaflets elliptic to orbicular, 

 truncate or rounded at base, coarsely toothed and often 3-lobed, 1 to 2 in. 

 long; peduncles 1 (rarely 3) -flowered, 2 to 6 in. long with 2 bractlets usually 

 below the middle; flowers polygamous, 1% to 2^4 in. in diameter; sepals 

 broadly oblong; achenes 2 lines long, supporting a tail 1 in. long or more, 

 the fruit of one flower forming a head-like cluster 2 to 2i/> in. broad. 



Coast Eange and Sierra Nevada canons, clambering over low shrubs and 

 often illuminating a hillside with its profusion of flowers. Apr.-May. 



C. pauciflora Nutt. Rope Vine. Flowers solitary or few; achenes glab- 

 rous (in the preceding species the achenes are pubescent). — Southern Cali- 

 fornia, trailing over rocks or climbing trees. 



7. ANEMONE L. Wind-flower. 



Perennial herbs, the stems and radical leaves from a rootstock. Cauline 

 leaves none except an involucral whorl of 3 near to or distant from the solitary 

 or umbellate flowers. Sepals 5 to 8, petal-like, imbricate. Petals none. Sta- 

 mens numerous. Achenes numerous, the style short or developing into a long 

 plumose tail. Seed suspended. (Greek anemos, wind, the flowers disturbed by 

 the wind.) 



1. A. quinquefolia L. var. grayi Jepson. Wood Anemone. Stems slen- 

 der, 1-fl.owered, 4 to 12 in. high, from a horizontal rootstock; radical leaf simple, 

 of reniform outline, trifid; involucral leaves 3-foliolate, petioled; leaflets obo- 

 vate, entire at base, crenately toothed or incised above, the lateral usually 

 oblique, % to 1% in. long; flowers white or pale blue, 6 to 8 lines broad; 

 ■epalfl about 6; achenes with short recurved style. 



Shady mountain woods: Santa Cruz Mts. ; Mt. Tamalpais; Humboldt Co. 



A. DELTOIDEA Hook. Near the last; radical leaf 3-foliolate; involucral leaves 

 sessile; acheue with straight style. — Humboldt Co. and northward.
