1. N. aurita Lindl. Herbage scabrous with stout recurved 

 prickly hairs, the smaller often uncinate; stems weak, clinging 

 to other plants for support by means of the prickles; leaves 

 deeply pinnatifid, the lobes somewhat reflexed ; petioles winged, 

 clasping at base ; flowers in few-flowered racemes at the ends of 

 the branches; corolla 12-25 mm. broad, purplish violet; scales 

 triangular, covering the base of the filaments; capsule globose ; 

 seeds 4, globular, favose-reticulated. 



Common on shady slopes throughout our range below 3000 feet. March- 

 April.

 prickly; leaves often bipinnatifid ; petioles not strongly winged, 

 not clasping ; flowers distinctly racemose, less than 10 mm. broad,

 where it was first collected by Nuttall. It has also been collected on 

 Catalina and San Clemente Islands. March-May. 



3. N. insignia Dougl. Stems much branched, spreading, 1-3 

 dm. long, nearly glabrous or somewhat pubescent with more or less 

 retrorse hairs ; leaves mostly bipinnatifid, pubescent with spread-

 25-45 mm. long; calyx-lobes ovate-lanceolate, acute; corolla
