This is probably the Asarvwm arifolium of Dr. Chapman’s Flora, 
but not the plant of Michaux, specimens of which I have never 
seen from further south than Georgia. It differs from Asarum 
arifollum in both foliage and infloresence. The leaf-blades are 
simply ovate, and lack the halberd-shape so characteristic of those 
of the Michauxian plant, and the margin instead of being entire 
is finely undulate or crenulate. The pedicels are always short, 
never elongating like those of A. arifolium, while the perianths 
of the two species are entirely dissimilar in shape; that of Asarum 
callifolum being larger, much shorter in proportion to the length 
and with a rounder base. 
“ ARISTOLOCHIA CONVOLVULACEA. 
Perennial, slender, bristly-pubescent throughout. Stems erect 
or decumbent, 1-3 dm. long, angled, slightly flexuous, simple, or 
rarely branched below; leaves thinnish, becoming firm at ma- 
turity, broadly ovate to oval, 2-8 cm. long, short-acuminate or 
rarely acute, ciliate, deeply cordate at the base, short-petioled ; 
petioles .5-1.5 cm. long, hirsute; peduncles slender, 1-2-flowered, 
flexuous, angled; calyx densely hirsute, the tube .5-1 cm. long, 
the limb 6-8 mm. broad, scarcely lobed; capsule subglobose, 6-7 
mm. in diameter, pubescent. 
In woods,“ . . . Columbus, Georgia. Grows from Athens 
to near this place” (Boykin). 
Dr. Boykin noticed the differences between Aristolochia Serpen- 
‘ana and the one here described as new, many years ago. Besides 
observing the plant in the field, he cultivated it in his garden, and 
sent both native and cultivated specimens to Dr. Torrey in whose 
herbarium they are preserved. 
Aristolochia convolvulacea can readily be distinguished from 4. 
Serpentaria by either the pubescence or the foliage. In place of 
the soft pilose hairs characteristic of Aristolochia Serpentaria, we 
find a bristly-hirsute pubescence on all parts of the plant. The 
leaves are much broader in proportion to their length than those 
of its relative, resembling closely those of some Convolvulaceae, 
whence the name. 
PARONYCHIA SCOPARIA. 
Perennial, rather slender, the foliage minutely pubescent. 
Stem much branched at the base, the branches tufted, erect or
