 or less, unequal lobes somewhat rotately spreading, the lower not

 Nearly glabrous; stem weak and filiform, diffusely branched froin the base, 

 6-12 inches long : lower leaves round or reniform in outline more or less 

 deeply 3-5-lobed or trifoliolate, on slender petioles longer than the blade, 

 the others short-petioled or sessile, ovate to lanceolate, coarsely toothed 

 to entire, many of them 3-parted or else quite divided into oblong or lan- 

 ceolate divisions or leaflets; the uppermost in whorls of three, simple and 

 shorter than the long filiform pedicles : corolla blue, a line long, its 5 lobes 

 of equal length', the lower one transversly oval or roundish very much 

 larger than the oblong lateral and upper ones and separated from them by 

 deeper sinuses : ovules solitary in the cells : capsule globose, longer than 

 the calyx. Common in shady places, Brit. Columbia to California.
