II. New SPECcIEs. 
LISTERA RENIFORMIS. 
Perennial, fleshy, deep green. Stem erect, 1-3 dm. tall, slender 
glabrous or nearly so below, densely glandular-pubescent above, 
simple; leaves 2, opposite, about the middle of the stem, reniform 
or ovate-reniform, 1-3 cm. in diameter, apiculate or short acumi- 
nate, glabrous above, more or less pubescent beneath, cordate or 
subcordate, sessile; racemes 2-10 cm. long; flowers greenish; 
bracts lanceolate or ovate-lanceolate, 3-5 mm. long, acute; pedi- 
cels slender, 4-7 mm. long, glabrate, or much less pubescent than 
the stem; sepals oblong or linear oblong, about 3 mm. long, ob- 
tuse or acutish, reflexed ; lip wedge-shaped, 6-7 mm. long, with 2 
prominent teeth on both sides near the base, sharply cleft to near 
the middle, the lobes rounded; capsules oval, 4-5 mm. long; 
mature seeds not seen. 
Damp thickets on the mountains of Maryland, Virginia and, 
North Carolina, ranging from about 1000 to 1750 meters altitude. 
Spring and summer. 
It seems strange that this well marked species should have 
been so long associated with the northern Lzstera convallarioides 
It is confined to the higher parts of the southern Alleghany 
mountains, while Lzstera convallariides appears to have a northern 
transcontinental range suggesting that of Polygonum Douglasit. 
Listera reniformis differs from its northern relative in its more 
slender habit, the reniform type of the leaves, which are apiculate 
or short-acuminate at the apex and cordate or subcordate at the 
base, and the lip, which is sharply cleft, often nearly to the middle, 
by a V-shaped sinus. The leaf of Listera convallarioides is oval 
and obtuse at both ends, while the lip is cut by a U-gfaped sinus. 
V ASARUM CALLIFOLIUM. 
Perennial, deep green, nearly glabrous. Leaves tufted, long-pe- 
tioled, the blades ovate, 5-9 cm. long, obtuse or sometimes acutish, 
finely undulate or crenulate, rarely mottled, deeply cordate at the 
base; petioles 2-3 times longer than the blades, sparingly pubes- 
cent; bracts reniform, ciliate; pedicels as long as the calyx, or 
much shorter; calyx urn-shaped, 1.5-2.5 cm. long, dark green 
without, dark purple within, the segments broadly ovate or 
broader than high, the throat slightly contracted; stigmas 2-cleft, 
capsule not seen. 
In shady woods, Florida. (Chapman.)
