Heller's specimen No. 7630 from near Oil City is unique among 

 those seen in that the pods are erect. The stem is also more 

 nearly glabrous than is usual for C. Coulteri. In these charac- 

 ters it approaches C. Lemmonii but the stigma is less deeply lobed 

 than in that species. The insertion of C. Coulteri among the 

 erect-podded species in the key is made because of this specimen.

Annual, pilose on the lower leaves and towards the base of 

 the stem, otherwise glabrous and glaucous: stem erect, simple 

 or branched above the base, 2-8 dm. high : leaves sessile, auricu- 

 late-clasping at the base; lowermost oblanceolate or oblong, 

 dentate, denticulate or entire, 2-10 cm. long; upper entire, sagit-

 crisped, white with dark purple veins; stamens in three pairs 

 similar to those of C. Coulteri : inflorescence racemose ; pedicels
