II. New Species. 



LiSTERA RENIFOKMIS. 



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 Listera cdnvallarioides 

 It is confined to the higher parts of the southern Alleghany 

 mountains, while Listcra convallarioides appears to have a northern 

 transcontinental range suggesting that of Polygoimin Douglasii. 

 Listera renifornnis 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-shaped sinus. 



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.)
