§ 3. Stemless, or sometimes a leaf or two on the lower part of the scape, no perma- 

 nent caudex rising above the ground: calyx 5-parled or 5-cleft : 2ietals almost 

 alwai/s ivhite. 

 * Leaves not cordate, contracted at base into a margined petiole or nearly sessile: fila- 

 ments not enlarged upivard or rarely slightly so: herbage or at least the mjlores- 

 cence more or less glandular or viscid-pubescent. 



+ Naked simple scape and cluster of rather large thickish leaves rising from a short 

 and thickish root or caudex: base of calyx coherent with the base of the '1 parted 

 ovary : petals roundish, obovale or oblong-spatulate, very obtuse ; the claw very short 

 or none. 



3. S. Virginiensis, Michx. Leaves IVuiu rouiulish- to oblong-ovate or .spatulute- 

 obovate, coarsely louLlietl or almost entire, an inch or two long, and tlie margined 

 petiole often as long : sca[)e a si)an to a I'oot liigli, at length loosely many-flowered 

 in a paniculate cyme : some of the pedicels slender : petals obovate, twice the length 

 of the merely spreading calyx. 



Shaded rocky jilaces in the Coast Ranges and Siena Nevada : also in Oregon, the IJocky Moun- 

 tains, and conniiou in the Atlantic Status. The (.'ulilornian specimens resemble slender lurins of 

 the common venial eastern species. 



4. S. nivalis, Linn. Like the jirecoding, but mostly smaller and cdndc^nsed : 

 scapo 2 to 5 inches high : llowers fewer, sessile or very short-pedicelled, ami crowthnl 

 in a cajjitato sinii)le or compound cluster : petals oblong or s[)atulate, lil tie exceed- 

 ing the erect calyx-lobes : styles very short or hardly any : ovary and fruit usually 

 dark puiple. 



High Sierra Nevada, above the Yosemite {Brewer) and above (!isco (Bolander) ; thence to the 

 arctic regions, &c., and lound the frigid zone. The var. tenuis, Walil. (E. Humboldt Mountains, 

 Watson, thence northward and eastward), may occur in the State. It has more o|ten inllores- 

 cence, ratiicr larger petals, and pi<)l)ably passes into IS. rirt/iuicnsis. Its lilaments are not rarely 

 distinctly hroadcued above the middle. 



5. S. integrifolia, Hook. Leaves from ovato or obovato to lanceolate-spatulate, 

 1 to 5 inches long, denticulate or entire, narrowed at base into a very short anil 

 niargineil (or rarely longi^r and more distinct) petiole; : scai)e 1 to 3 fei't high, viscid : 

 Howers in small clusters usually in a narrow thyrsiform panicle : petals obovate or 

 broadly si^atulate, somewhat longer than the rellexed calyx-lobes : seeds nuudi larger 

 and with a loo.ser coat than in the foregoing. — Fl. i. 2-49, t. 86 ; Watson, IJot.

Swamps, through the font-hills of the Sierra Nevada, thence northward to Wa.shiiigdin Terri- 

 tory, and east to the (!oloiado ilocky Mountains. 



+- -<- Slender scapes often panicalately branching and hracteate, and, with the tuft if 

 thinner leaves, from a small annual or biennial root or offset : calyx free from the 

 two almost distinct ovaries and rejlexed : petals acute, on distinct claws, '2-spotted 

 towards the base : filaments Jillform : info)-escence not rarely bearing leaf-buds or 

 hulblets in place of blossoms. 



6. S. bryophora, (Iray. Slender root or offshoots annual : leavtss linear ohlong 

 or spatulate, (uitire, ihickish ami muirly veinless, barely half an inch long, almost 

 sessile, sparsely ciliate : scape glabrous, loosely paiaculate and with filiform branches 

 and pedicels, flowering only at the apex ; the lateral branches or pedicels bearing a 

 green globose leaf-bud or bulblet, soon deflexed : flower 3 or 4 lines in diameter : 

 petals oblong-ovate, slightly unequal, and with a pair of yellowish spots at the 

 abrupt base, twice the length of the broadly ovate and rellexed sepals: styles hardly 

 any. — Proc. Am. Acad. vi. 533. ,S. leucanthemifolia, var. integrifolia, Engler,
