SAXIFRAGE.E. 195 



nearly leafless and almost glabrous : fl. loosely panicled ; calyx 2 lines 

 long, oblong-campanulate, tinged with rose-color ; linear petals and fili- 

 form filaments white or pinkish. — At higher altitudes in the Sierra, 

 thence eastward. July — Oct. 



2. H. iiiicrantha, Dougl.; Lindl. Bot. Reg. xv. t. 1302 (1830). Leaves 

 thin, 13 in. broad, ovate-cordate, 5— 9-lobed, hairy on the veins beneath : 

 stem villous, bearing a few small leaves and a loose panicle often 1^2 ft. 

 long : calyx campanulate, 1—2 lines long, acute at base, shorter than the 

 slender pedicels, puberulent : narrowly spatulate petals and slender 

 filaments white, well exserted. — Common in shady ravines both of the 

 Coast Eange and the Sierra. May — July. 



3. H. pilosissima, F. & M. Ind. Sem. Petr. v. 36 (1838) : H. hirliflora, 

 T. & G. Fl. i. 582 (184:0). Hirsute with rusty and viscid spreading hairs : 

 leaves 1 — 3 in. broad, round-cordate, obtusely lobed and crenate : stem 

 1 — ^% ft. high, naked or few-leaved, rather densely and thyrsoidly 

 paniculate : calyx densely hairy, subglobose, the tube rounded, the lobes 

 incurved : filaments and narrowly spatulate petals little exserted. Var. 

 Hartwes"i? Wats. Stems 2—3 ft. high : panicle more open ; the whole 

 plant, and especially the calyx, less hairy. — In the Coast Eange, and 

 apparently not common ; at all events seldom seen. 



9. PARXASSIA, Tonrnefori (Geass-of-Parnasstts). Glabrous stem- 

 less perennials, with entire petioled exstipulate leaves and simple 1- 

 flowered scapes. Calyx 5-parted ; the base free from or adnate to the 

 base of the ovary, somewhat imbricate in biid. Petals 5, oval or oblong, 

 imbricate in bud, white, with conspicuous green veins, widely expanding, 

 tardily deciduous. Stamens 5, alternating with the petals, and with as 

 many clusters of short gland-tipped sterile filaments. Ovary ovate, 

 1-celled, with 3 or 4 parietal placentae ; stigmas as many, closely sessile 

 each directly over its corresponding placenta. Capsule 3— 4-valved from 

 the apex, the valves placentiferous in the middle. Seeds with a thickish 

 and somewhat winged loose testa, and little or no albumen. 



1. P. Califoruica, Greene, Pitt. ii. 102 (1890) : P. palustiu, var. Cali- 

 foriiica, Gray, in Bot. Calif, i. 202 (1876). Radical leaves ovate or ovate- 

 oblong, 1—2 in. long, tapering from the broad and sometimes slightly 

 rounded base to a long or short petiole : scapes 1 — 2 ft. high, the very 

 small sessile but not clasping leaf borne much above the middle : petals 

 oval or obovate, sessile, entire, % in. long : sterile filaments about 20 

 in each set, united to the middle, each tipped with a conspicuous antheroid 

 protuberance. — In wet places at considerable elevations in the Sierra. 

 P. palustns is not likely to occur within our limits. It is very distinct 

 from the present species by its cordate radical leaves, and by that of the 

 scape being also large, cordate-clasping and inserted low, near the 

 radical ones.
