48 ENGLISH BOTANY. 



1 to 4 inches long, very thick, coriaceous, evergreen, with a firm carti- 

 laginous suhcrenate or nearly entire margin, sometimes progressing 

 into callous points. Scapes 6 inches to 1 foot high, of which about 

 one half is occupied by the raceme, which has from 10 to 20 flowers. 

 Bracts rather longer than the pedicel, scalelike. Flowers -J inch 

 across. Petals roundish or broadly oblong-obovate, pure white. An- 

 thers yellow, inverted on the filaments as in the rest of the genus. 

 Stigma purplish. 



Var. j3 has the scape 3 to 6 inches high, with fewer flowers, and 

 generally with several empty bracts below the inflorescence, com- 

 mencing from the base. Leaves ^ to 1 inch long, and the petioles 

 about twice as long, seldom more than 2 inches long. Calyx-seg- 

 ments much broader than in var. a, especially in the specimens from 

 Southport. Plant deep-green, quite glabrous. 



Round-leaved Winter-green.

Leaves all in a terminal rosette, coriaceous, orbicular or 

 broadly-oval, abruptly contracted into the petioles, or sometimes 

 even subcordate at the base, rounded or obtuse at the apex, entire 

 or repand, more rarely callous - denticulate. Elowers drooping, 

 in a rather short raceme at the termination of the scape. Calyx- 

 segments ovate, acute, entire. Petals very concave, connivent, 

 cream-white. Stamens incurved, not bent upwards. Style bent 

 down, much longer than the stamens, and slightly exceeding the 

 petals, nearly straight ; stigma with an indistinct blunt-edged 

 elevated ring, above which there are 5 blunt erect lobes. Capsule 

 drooping ; style not twice as long as the capsule. 



On heaths. Rather scarce, but widely distributed. In Sussex, 

 Worcester, and most of the counties in the North of England and 

 Scotland, probably extending to Shetland, and co. Antrim, Ireland. 



England, Scotland, Ireland. Perennial. Late Summer 



and Autumn. 



Very like P. rotundifolia, but generally with the petioles shorter ; 

 the scape (which is 6 to 12 inches high) longer in proportion, and the 

 raceme occupying a less portion of it, often not more than a third or 

 fourth ; the flowers are less pure-white, frequently slightly tinged 

 with rose, little more than |- inch across, for, although the petals are
