Zanthoxylum Texanum.— Unarmed, leaves trifoliate, leaflets

punctate, petioles 4"-6" long, lateral leaflets serrate, petiole of term- 
inal one 3' -6" long; racemes terminal, compound, pedicels short, 
with minute, acute, bracts and bractlets; divisions of calyx broadly 
ovate, acute, ovules 1-2, seeds not seen- 
A large shrub 4-6, feet high, thickly branched; younger branches

the aromatic odor peculiar to many species of the genus.. 
Differs from Z. ternatum of the West Indies in its terminal racemes 
and crenate leaflets. Near Corpus Christi, Texas.

sides, and of the same pale green color, I'-i^' long and about |'
