saxifeagetE. 189 



blade rounded-subcordate, slightly crenate-lobed and -toothed, 1 in. 



broad or less ; petioles short : cyme lax, 3 — 7-fiowered : calyx only 



slightly 5-lobed, the campanulate brown-nerved tube nearly enclosing 



the 2-lobed capsule : petals ovate or spatulate, inserted by short claws 



nearly in the sinuses of the calyx, white, marked with purple or 



brownish veins : filaments slender-subulate, inserted below the petals : 



styles slender, in fruit exserted from the calyx. — A very remarkable 



species, long supposed to be peculiar to the dry hills of San Diego Co., 



there sending up its scapes and unfolding its flowers in November or 



December, the leaves appearing later in winter. It was fotind in our 



part of the State near lone, by Dr. Parry, in the autumn of 1887. 



***** Perennial, fibrous-rooted, the scape and leaves frorn a short 



crown; calyx partly adherent to the ovary; petals not 



Ufiguiculale; filaments not clavate. 



8. S. Califoruica, Greene, Pittonia, i. 286 (1889): S. Virghiieiisis, Gray, 

 Bot. Calif, i. 195, not Michx. Leaves few, rather thick, reddish-veined, 

 sparsely glandular-villous, oval, oblong or elliptical, 1 — 2 in. long, on 

 broad petioles of ^i—l in. ; margin coarsely crenate to repand-denticulate, 

 rarely either sharply dentate or nearly entire, tomentose-ciliolate : scape 

 6 — 18 in. high, loosely cymose-paniculate : calyx nearly free from the 

 ovary, the sepals reflexed : petals oblong, thrice the length of the sepals, 

 white or rose-tinted : filaments subulate, inserted under the edge of an 

 elevated perigynous disk which equals the summit of the ovary. — Plenti- 

 ful throughout the State, on cool northward slopes of both ranges of 

 mountains. In the Sierra Nevada the leaves are couspiciiously toothed. 

 In the Coast Eange they vary from crenate to almost entire. Mar.— May. 



9. S. nivalis, Linn. Sp. PI. i. 405 (1753). Plant deep green or purplish, 

 more or less viscid-pubescent : leaves oblong-ovate or spatulate-obovate, 

 1 in. long or less, coarsely dentate, or crenate, or almost entire : scape 

 1 — 6 in. high : fl. crowded or distant in a terminal cluster : calyx-lobes 

 ovate, longer than the tube, erect : petals white, oblong or spatulate, 

 exceeding the calyx : stamens filiform : styles very short : ovary and 

 fruit usually purple.— Common at alpine heights in the Sierra. June-Oct. 



10. S. iuteg:rifolia, Hook. Fl. i. 249, t. 86 (1833). Plant light or dark 

 green, more or less roughened with a short glandular pubescence : leaves 

 varying from ovate to oblong-lanceolate and -spatulate, acute or obtuse, 

 2—5 in. long, entire, remotely denticulate or more distinctly dentate or 

 crenate : scape 1—3 ft. high : fl. in small clusters in an interrupted 

 thyrse or panicle : petals obovate-spatulate, dull white, exceeding the 

 reflexed calyx-lobes : filaments short, broadly subulate : stigmas sessile 

 on the conical, at length widely divergent beaks of the ovary.— In swamps 

 of the middle Sierra ;_ extremely variable, and possibly a composite
