stated that the roots of the Asarum virginicum are found 
with it. 
Aristolochia reticulata. — Nutt. From a woody knotted 
caudex, from which numerous radicles are given off, there 
arise numerous short stems sometimes branched near 
the roots. They are slender, round, flexuose, jointed, 
and slightly villous in the old, but densely pubescent in the 
young specimens. The leaves are oblong, cordate, large, 
obtuse, reticulated with very prominent veins, villous on 
both sides, more particularly upon the veins and short 
petioles. The flowers are small, purplish, and densely 
pubescent, especially at the base and in the germ. The 
capsule is hexangular, deeply sulcate, sprinkled with 
scattered hairs, and bears at its apex the decayed corolla. —

This plant is a native of Arkansas, and brought from the 
neighborhood of the Red River. The roots differ from 
those of the officinal, in the filaments being coarse and 
less frequently interlaced. The odor and taste the same, 
but stronger. 
In commerce it is found in bales from one to three 
hundred pounds, with many of the stems and leaves inter- 
mixed, for the most part free from foreign substances. It 
is sometimes done up in small bundles, and in this state the 
filaments are much less interlaced. 
The root of the Ji. serpent aria has been analysed by 
Bucholz, in 1820, Chevallier, in 1823, and Pischier, in 1824
