the lowest pair of which is situated uniformly close to the insertion of the 

 petiole ; leaflets ovate, repand, spiny-dentate (In my specimens from 

 Southern Utah, the leaflets are hardly half an inch long. Torrey, how- 

 ever, in Bot. Mex. Bound, p. 31, states that the leaflets are from 1-2^'.) 

 Racemes erect, 5-7-flowered, longer than the leaves; pedicels over half an 

 inch long; flowers golden yellow, half an inch in diameter; filaments inap- 

 pendiculate ; berries large as currants. Its nearest affinity is with B. 

 trifoliata, but it has more leaflets, longer racemes, and blue instead of red 

 fruit. Arizona.

Corydalis aueea, Willd., var. occidentalis, Engelm. — Like our East-
