Sepals equal at base, erect or nearly so. Petals much longer 

 with slender claw and ovate blade. Pods linear, straight Avith 

 stout firm nerveless flat valves that do not separate elastically, 

 and nerveless partition. Stigma short, capitate or rarely 2-lobed. 

 Seeds in one row, wingless ; cotyledons often thick more or less 

 unequal and somewhat oblique, petiolate. Low, usually gla- 

 brous perennials with commonly simple stems, variously lobed 

 leaves and comparatively large campanulate flowers in very 

 early spring.

 3-5 lobed or coarsely toothed, 6-18 lines long, the petioles often bearing 

 bulblets on their underground portion : cauline leaves 1-2, sessile, deeply 3- 

 lobed or 3-foliolate with linear or linear-lanceolate entire obtuse segments, 

 6-12 lines long; racemes few-flowered, terminal and sometimes axillary: 

 flowers rose-purple : pods 1-2 inches long by a line broad, attenuate to a 

 slender style and a broad distinctly 2-lobed stigma. Very common in 

 woods, western Oregon and Washington, flowering in very early spring.

 branched : radical leaf simple from round-reniform to almost orbicular, 

 cordate at base 2-3 inches broad, sinuately lobed, the 9-15 lobes obtuse or 

 almost truncate, conspicuously mucronate; cauline leaves 2 or 3, divided 

 3-5 more or less cuneate leaflets which are iobed or coarsely toothed at 

 the apex: racemes lax, few-flowered: flowers large, rose-purple; pods 2-3
