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 
‘atthe apex. Style filiform, with small capitate stigma. ‘Capsule

the centre of the valves.. Seeds discoidal, orbicular or oval, with 
very close and strictly conformed smooth coat. 
§ 1 Acaulescent with naked scapes. Ovules and seeds only a 
pair in each cell, ona short partition. Capsule divaricately two- 
lobed, the cells transversely oblong. Seeds with thickened mar- 
gins incurved at maturity. | | 
S. rotundifolia Gray Syn. Fl ii, 285. Rootstock short and creeping,

ple scapes: leaf-blades 1-2 inches igi tiasatey; 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 
py 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. reniformis 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 thé’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-reniform, 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. pinnatifida 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.
