Leaves about an inch long, varying from nearly orbicular to broadly ovate or obovate, 

 sometimes retuse and a little cordate or unequal at the base, dark green ; the petiole 1-2 

 inches long, scarcely veined above, conspicuously but sparingly veined underneath. Scape 

 5-8 inches long, acutely angular, naked or with a solitary small scale. Raceme 5-8- 

 flowered, ol'ten secund ; the flowers smaller than in P. elliptica, slightly odorous. Calyx 

 about one-fourth the length of the corolla. Petals elliptical, a little spreading, greenish white. 

 Style longer than the corolla : stigma minutely 5-toothed. 



Dry sandy woods. Near Schenectady {Dr. L. C. Beck) ; Pine plains near Rome (Dr. 

 Knieskern) ; Penn-Yan {Dr. Sartwell) ; Rensselaer county {Dr. Wass), and in the northern 

 part of the State. June. 



4. Pyrola uliginosa, Torr. S^- Gr. (Plate LXIX.) Swamp Wintergreen. 



Leaves nearly orbicular, obscurely crenate-denticulate, coriaceous, longer than the petiole, 

 somewhat veiny, nearly dull ; scape bracteate ; raceme many-flowered ; calyx one-fourth the 

 length of the petals, the segments broadly ovate, acute ; stigma with five small erect teeth. — 

 Torr. 4- Gr. in Geol. report of N. York, 1841. 



Rhizoma long and creeping. Leaves 1^-2 inches in diameter, sometimes inclining to 

 ovate or obovate, of a pretty firm texture, abruptly decurrenl on the petiole at the base ; the 

 veins rather prominent, but not numerous. Scape 6-12 inches high, slriate-angular, fur- 

 nished with 2 — 4 conspicuous lanceolate bracts. Raceme 7 - 12-flowered, loose. Flowers 

 about two-thirds as large as in P. elliptica. Petals obovate-oblong, rather connivent, dull 

 purplish. Stamens ascending : filaments smooth : anthers (in the expanded flower) with two 

 short perforated hcHrns at the summit ; the lobes 2-celled, but the septum at length separating 

 from the connective. Ovary depressed-globose : style declined and flexuous, filiform-clavate, 

 distinctly annulate at the summit : stigma with five distinct obtuse teeth. 



Sphagnous swamps, Oriskany, Oneida county {Dr. Knieskern). June. This species is 

 intermediate between P. rotundifolia and P. chlorantha : differing from the former in its 

 smaller, less coriaceous and nearly dull leaves, smaller purplish flowers and much shorter 

 calyx ; from the latter in its larger leaves, bracteate scape and acuminate calyx-segments, as 

 well as in the color of the flowers.
