Bigelow, Thurber. Cation of the Guadaloupe river, Sonora; Capt. E. K. Smith. А handsome 
shrub 5—10 (rarely 15) feet high, Leaves coriaceous and rigid; leaflets 1—2} inches long, 
sometimes truncate or cordate at the base, the middle one usually much longer than the others, 
and with more numerous teeth ; the lowest pair situated close to the base of the petiole. On 
some specimens the primary leaves are reduced to small branching prickles, as in Berberis 
proper. Racemes 1—3 together; the pedicels 4—5 lines long. Flowers about as large as 
in the common Barberry. Filaments inappendiculate. Berries somewhat ovate, dark blue, 
about the size of currants. This species was first discovered by Frémont, in 1844, on the 
tributaries of the Rio Virgen, in southern Utah. It is nearly allied to B. trifoliata, but differs 
in the number of leaflets, longer racemes, and blue berries.
