(D e c . Prod.) A deciduous shrub. Canada to Florida. Height 3 ft. to 8 ft.
Intro d u ced in 1688. Flowers yellowish g re e n ; Ju ly and A ugust Berries
red ; ripe in September. Decaying leaves purplish red.
Varieties. Three forms are given by Torrey and Gray : — a . Leaflets entire,
usually acuminate, which may be considered as th e species ; ß, leaflets
coarsely and unequally s e rra te : and y, leaflets (a b o u t 2 1 ) small, oblong,
acute a t the b a se ; obtuse and slightly mucronate a t th e a p ex ; petiole nar
rowly winged. Jacquin has

Schön., t. 3 4 2 .— R o o t not
stoloniferous. Panicles more
contracted th an in the
species.
T h e leaves and general habit of
th e plant are those o f R . typhina,
b u t it seldom grows to th e height o f
more th an 4 or 5 feet in British
gardens. The branches are smooth,
and the leaflets entire with acute
p o in ts ; th ey are light green on both
sides, and in autumn change to a fine
p u rp le .. The petiole, as in R. Coriària,
is somewhat winged towards its
tip, which, with o th e r circumstances,
induces us to think th a t they may both
be varieties o f the same species. The
leaves are used as tobacco by the
Indians o f the Missouri and th e Mississippi.
