184 CLASS X. ORDER I. 



Pyrola ROTUNDiFOLiA. L. Routid Uavcd Winter green. 



Leaves prolate-orbicular^ flowers racemed, calyx 

 reflexed, style declined. 



A very common species. Root creeping, putting up erect or 

 ascending, angular stems. Leaves spreading near the ground, 

 petioled, roundish ovate and obovate, subacute, scarcely serrate, 

 much larger than in the following species. Scape angular, with 

 one or more sheathing scales. Flowers in a large terminal ra- 

 ceme with nodding pedicels, white, fragrant. Calyx segments 

 ovate Avith the points reflexed. Stamens tending to the upper 

 side, and styles to the lower; stigma truncately-conical surround- 

 ed with a ring at base, persistent. — Common in Woods. — June. 



Pyrola asauifolia. JMx. Broad leaved Winter green. 



Leaves oblate orbictilar, Howers racemed, calyx ap- 

 pressed, style declined. 

 Syn. Pyrola CHLORANTHA. Nuttall? 



This species is in flower two or three weeks earlier than the 

 last, and has leaves which are broader in proportion to their 

 length, but scarcely half as large. Primary leaves reniform, 

 sometimes obcordate, sometimes orbicular, obtuse, dark green 

 and coriaceous. Scape more slender and fewer flowered than in 

 the last. Flowers greenish with the segments of the calyx 

 short and appressed. Stamens, style, and stigma much as in the 

 last. — Dry woods, less common than the last. — June. 



Pyrola elliptica. Nutt. Oval leaved Winter green. 



Leaves elliptic-ovate, membranaceous ; calyx very 

 short with reflexed points; style declined. 



The affinity of this and the two foregoing species seem to 

 render it not improbable that they may all have descended from 

 the same stock. Leaves thin and membranous, serrulate, rather 

 acute. Scape angular, with about one bracle or scale. Flowers 

 white smaller than in P. rotundifolia. — Woods. — Hubbardstown. 

 — Mr. Russell. — June.
