a plantin th e garden of the London Horticultural Society, and several

Spec. Char., 4’». Leaves pinnate ; th e leaflets 3
to 5 pairs, and an odd one, all on short stalks,
oblong oval, acuminate, finely sawed, oblique at
th e base. Petioles and branches prickly. P a nicles

Height 1.0 ft. to 15 ft. In trod. 1806. Flowers
greenish ; June. Seeds large, black ; ripe Oct.
Leaves and bark very aromatic and pungent.
Prickles very sharp. The bark o f this and the
preceding species is imported from New York,
and sold in Covent Garden Market as a cure for
the rheumatism. Probably a variety o f th e preceding
species.
Other Species of Xanthóxylum.— X. mite Willd., tre a ted as a species by
some authors, is made a synonyme o f X .yfaxineum by Torrey and Gray, and
it probably bears the same relation to th a t species th a t Gleditschia inérmis
does to G. triacànthos. O ur opinion is, th a t th e re is only one species o f the
genus in British gardens.
