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 1^-2 inches long and of 

 nearly the same diameter (in the var. asarifolia, 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 liule 

 refle.xed at the tip. Petals white, or sometimes with a slight rosaceous tinge, obovate-oblong, 

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

 completely 2-celIed, even \ hen old. Style rather longer than the corolla : stigma with a ring 

 or minute collar near the extremity ; the disk with 5 little 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 fragraiH I follow 

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

 of this latter botanist, P. rolundifolia is mixed with P. elliptica. 



2. Pvrola elliptica, Nutf. ' Shin-leaf. 



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

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

 the length of the corolla , the segments ovate ; stigma v\'ith 5 -obscure teeth — Nutt. gen. 1 .

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-anglcd, with rarely 

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

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

 white. Staniens, style and capsule nearly as in the preceding species. 



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.
