ON ARISTOLOCHIA. 
121 
The hirsuta is allied to the species with subradical pedun- 
cles — serpent, hastata, &c, and not to those bearing axillary 
flowers, tomentosa, sipho, &c. It is an herbaceous plant, with 
a knotty caudex, sending off numerous slender, simple fibres, 
some of which are more than six inches in length, of a yel- 
lowish color, aromatic odor, and aromatic bitter taste. It 
sends off several jointed, flexuose pubescent stems, bearing 
one or two pubescent bracts and several leaves at the joints. 
Leaves large, cordate, rounded, obtuse, becoming as they rise 
on the stem abruptly acuminate, pubescent on both sides and 
margin, petiolate; petioles pubescent and bracteolate; principal 
veins more prominent than in serpentaria, and very pubescent 
on each side. From the lowest joints near the root, there are 
produced several solitary peduncles, (1 to 3) each bearing 
three to four leafy bracts, and one flower. The peduncles are 
hirsute, with long scattered hairs ; the bracts hairy, and 
when young thickly covered with short, whitish hairs ; co- 
rolla hairy, more evident at the base; germ pubescent. 
This article has not been met with for certain in this 
market; but may be in the southern market, undistinguished 
from the Serpentaria. The leaves, &c, being not very dis- 
similar in form to those of the latter, it may have been taken 
for it ; or if the pubescence were noticed, for the tomentosa ; 
the characteristic leaves of which are said to have been de- 
tected in the parcels brought to this market.
