ly wanting. Stamens 2. rarely 4, inserted on the corolla, or on 

 the outside of the hypogynous disk, exserted: filaments slender: 

 anther-cells parallel or somewhat divergent below, not confluent 

 at the apex. Style filiform, with small capitate stigma. Capsule 

 compressed, obtuse or emarginate. Placenta short, chiefly at

 very close and strictly conformed smooth coat. 



1 Acaulescent with naked scapes. Ovules and seeds only a 

 pair in each oell, on a short partition. Capsule divaricately two- 

 lobed, the cells transversely oblong. Seeds with thickened mar- 

 gins incurved at maturity. 



S. rotniidifolia Gray Syn. Fl ii, 285. Rootstock short and creeping, 

 bearing a tuft of cordate-orbicular long-petioled persistent leaves and sim- 

 ple scapes: leaf-blades 1-2 inches in diameter, doubly crenate or crenate- 

 incised, slightly pubescent, especially on the veins beneath : petioles and 

 scapes pubescent with brownish hairs": scapes 4-6 inches high, about equ- 

 alling the leaves, naked except the ovate-lanceolate floral bracts: flowers 

 few, in a terminal raceme : pedicels slender, 4-6 lines long, each subtended 

 by a small bract : calyx-lobes ovate, acute, ciliate, 3 lines long : corolla 

 blue or purple, about 4 lines long. In open woods on rocky soil, western 

 Washington to California: flowering very early, often in January. 



2 Ovules and usually seeds several or numerous in each cell. 

 Capsule merely emarginate, Seeds plain, or meniscoidal. thin- 

 edged. 



S. rcniformis Benth. 1. c. Rootstock short and branching : herbage 

 glabrous: radical leaves persistent, orbicular- reniform, crenately incised 

 and the small lobes sharply toothed, 1-3 inches in diameter, on stout 

 petioles 3-6 inches long: flowering stems 6-10 inches high, bearing several 

 small bract-like fan-shaped alternate, or the lowest opposite, leaves and 

 numerous flowers in a dense terminal raceme : pedicels slender, shorter 

 than the subtending cuneate or lanceolate bracts : calyx-lobes lanceolate, 

 about 2 lines long : corolla blue changing to purple, 3-4 lines in diameter; 

 capsule truncate, emarginate. On rocky banks of the Columbia river and 

 in the mountains of eastern Oregon and Washington : flowering in early 

 spring. 



S. major Heller. *S. reniformis var. major Hook. Glabrous: leaves 

 persistent, orbicular-reri if prm, 1-4 inches in diameter, somewhat coriaceous, 

 with multilobulate margins, on petioles 2-4 inches long : flowering stems 

 longer than the leaves, bearing several fan-shaped bract-like leaves below, 

 and a dense spike-like terminal raceme of purple flowers: pedicels slender, 

 shorter than the subtending bracts: calyx-lobes lanceolate, about 2 lines 

 long : corolla purple, 3-4 lines broad : capsule strongly emarginate. Fertile 

 northerly slope of high mountains, Idaho. 



S. pinnatiftda Watson Bot. King. 227, t. 22. Somewhat villous : rad- 

 ical leaves long-petioled, broadly ovate in outline, pinnately divided, the 

 lowest of the 3 or 4 pairs of lobes nearly distinct, the upper confluent, all 

 laciniately pinnatifid and the segments laciniately toothed: flowering 

 stems 3-8 inches high, usually exceeding the leaves, naked below : raceme 

 1-2 inches long, densely flowered above : pedicels shorter than the subtend- 

 ing ovate or oblong toothed or entire bracts: calyx-lobes oblong, mostly 

 obtuse: corolla whitish, nearly twice longer than the calyx, the lower lip 

 deeply 3-lobed, the upper one entire: capsule elliptical, turgid. On rocky 

 ridges in the high mountains, Idaho to Utah.
