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 1-24.) 
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.
