tinguished by a more upright habit of growth, and smoother branches 
and leaves, than R. glabra, The leaves are glaucous underneath ; 
and the fruit is of a rich velvety crimson. 
The general appearance of the species is similar to that of R. typhina ; 
but the leaves and the entire plant are smaller, the branches more spreading 
and smooth, and the leaflets wider, less serrated, and of a deeper green.

Spec. Char., §c. Leaf rather glabrous than pubescent, of 5—6 pairs of leaflets, 
and the odd one, which are ovate-janceolate, acuminate, entire, and beneath 
reticulately veined. (Dec. Prod.) A deciduous shrub. Canada to Georgia, 
and west to Louisiana, in swamps. Height 15ft. to 20 ft. Introd. 1713. 
Flowers green; July. Berry smooth, greenish white; ripe in ? October. 
Decaying leaves intense red, or purple. 
Naked young wood purplish green. 
The leaves are divided like those of R. 
typhina and R. glabra; but they are quite 
different from those of both kinds, in being Q 
smooth, shining, and having the leaflets very 
entire, narrow, and pointed, and the veins of 
a purplish red colour. The whole shrub is 
ina high degree poisonous.; and the poison is 
communicated by touching or smelling any 
part of it. In British gardens it is not very 
common ;. but it well deserves culture, on 
account of the beauty of its smooth shining 
foliage at all seasons, and of its almost un- 
paralleled splendour in the autumn, from the 
time that the leaves begin to change colour, 
till they ultimately drop off, of an intense 
purple or scarlet, with the first frost. abt Rhasvencnstas
