* Listera nephrophylla. 



Stem slender, 1-2 dm. high, glabrous, and slightly pubescent just 

 above the leaves, two-leaved at the middle: leaves rounded reniform, 

 about 2 cm. long and 2—2.5 C'^'^- wide, sessile, strongly veined and 

 reticulated, obtuse or mucronate : flowers greenish, 5—6 mm. long ; 

 sepals and petals oblong, 1.5-2 mm. long: lip 4-5 mm. long, 2-clett, 

 with linear-lanceolate acuminate somewhat divergent lobes and two 

 papillose teeth at the base, divergent and directed somewhat back- 

 ward ; capsule broadly obovoid ; stamen strongly incurved and de- 

 pressed over the stigma. 



It is closely related to L. cordata (L.) R. Br., and has been mis- 

 taken for that species. All specimens from the Rocky ^Mountains re- 

 ferred to the latter may belong to L. nephrophxlla. This species 

 differs from its eastern ally in the greenish, not purplish, and larger 

 flowers, broader sepals and petals, broader reniform and more 

 strongly reticulated leaves, and slight differences in the form of the 

 basal teeth of the lip and the stamen. In L. cordala the teeth are 

 curved forward and the stamen ascending. JL. iicp/irop/iylla grows 

 in moist shady woods up to an altitude of 2500 m.
