var. asarifolia : leaves larger, reniform-roundish. Hook. I. c. P. asarifolia, Michx. I. c. ; 

 Pursh, I. c. ; DC. I. c. excl. syn. Torr., Bigel. <^ Nutt. 



Rhizoma long and horizontal. Leaves all radical ; the lamina \\ — 2 inches long and of 

 nearly the same diameter (in the var. asmijolia, broader than long), deep green, often 

 spreading, or lying flat on the ground : petiole margined. Scape. 8-12 inches high, angular, 

 furnished with several lanceolate scales instead of leaves, 8 - 20-flowered ; the flowers about 

 three-fourths of an inch in diameter, fragrant. Segments of the calyx rather acute, a little 

 reflexed at the tip. Petals white, or sometimes with a slight rosaceous tinge, obovatc-oblong, 

 obtuse. Stamens shorter than the corolla : filaments smooth : anthers oblong ; the lobes 

 completely 2-celled, even when old. Style rather longer than the corolla : stigma with a ring 

 or minute collar near the extremity ; the disk with 5 liille teeth or lobes. Capsule depressed- 

 globose, obtusely 5-angled ; the valves connected on the margin by fine woolly hairs. Seeds 

 very minute, tapering at each end ; the nucleus much smaller than the loose translucent testa. 



Rich woodlands ; not rare. Fl. Early in July. This species is also a native of Europe. 

 Like the following it is a very ornamental plant, and its flowers are highly fragrant I follow 

 Hooker, without hesitation, in referring here the P. asarifolia of Michaux. In the herbiirium 

 of tliis latter botanist, P. rotundifolia is mixed with P. elliptica. 



2. Pyrola elliptica, Nutt. Shin-leaf. 



Leaves elliptical-ovate, plicate-serrulate, membranaceous, dull, longer than the petiole ; 

 scape many-flowered, naked or with a single subulate bract ; ca'yx 5-cleft, scarcely one-fifth 

 the length of the corolla , the segments ovate ; stigma with 5 obscure teeth — Null. gen. 1 .

 lingt. fl. Cest. p. 265 ; Hook. fl. Bor.-Am. 2. p. 46. t. 134 ; DC. prodr. 7. p. 773. 



Leaves all radical, sometimes oblong or inclining to obovate, obtuse or somewhat acute, 

 abruptly decurrent on the petiole. Scape 6-10 inches hi^h, about 5-angled, with rarely 

 more than a solitary bract, which is situated near the summit. Raceme 8 — 15-flowered ; the 

 flowers very sweet-scented. Teeth of the calyx broad, acuminate. Petals obovate, obtuse, 

 white. Stamens, st3le and capsule nearly as in the preceding si)ecies. 



Rich fertile woods ; common. Fl. June. This is easily distinguished from the preceding 

 species, by its longer thin and dull leaves, and the much shorter calyx.
