(.350 THE HEATH FAMILY. 



2. Ziarger TVintergreen. Pyrola rotundifolia, Linn. 



(Eng. Bot. t. 213.) 



A larger plant than the common W., with larger and whiter flowers, and 



the petals more spreading, but chieflT distinguished from it by the long, 



protruding, much curved style, usually at least twice as long as the capsule, 



with a much smaller stigma, with short, erect lobes. 



In similar situations and with nearly the same range as the common W.; 

 extending further into central Asia, but not so frequent in Europe, and rare 

 in Britain. Fl. summer. 



3. Zutenuediate ^Vintergreen. Psrrola media, Swartz. 



(Eng. Bot. t. 1945.) 



Perhaps a mere variety of the common W., and sometimes passing almost 

 into the larger W. It diifers from the former chiefly by the style, which is 

 considerably longer, although nearly straight, and never so curved as in 

 the larger W. The size of the flower is variable. 



The geographical range and stations are the same as those of the common 

 W., but it is not near so common. 



4. Common Wintergreen. Pyrola minor, Linn. 

 (Eng. Bot. t. 158; and T. rosea, Eng. Bot. t. 2543.) 



Stock perennial, slightly ereepmg, retaining a few leaves during the winter 

 intermixed with scales produced at the base of each year's shoot. Leaves 

 on rather long stalks, collected three or four together in one or two tufts at 

 the top of the stock, broadly ovate or orbicular, rather thick, entire or 

 slightly crenated, with a minute tooth or gland in each notch, scarcely visible 

 without a glass. Peduncle erect, from 4-or 5 inches to twice that height, 

 leafless or with one or two small scales. Flowers drooping, in a short, loose 

 raceme, not turned to one side as in the following species, each one in the 

 axil of a small, narrow bract. Sepals short and broad. Petals ovate or 

 orbicular, quite free, but concave and closing over the stamens, usually of a 

 pale pink. Stamens shorter than the coroUa. Style scarcely protruding or 

 even shorter than the corolla, straight or nearly so, with a bi'oad, 5-lobed, 

 spreading stigma. 



In woods and moist shady places, in Europe, northern Asia, and the 

 extreme north of America, becoming a mountain plant in southern Europe 

 and the Caucasus. Frequent in Scotland, northern England, and Ireland, 

 more local in southern England. Fl. summer. 



5. Serrated ^Vintergreen. Pyrola secunda, Linn. 

 (Eng. Bot. t. 517.) 



Leaves ovate, more pointed, and often more distinctly toothed and more 

 prominently veined than in the common W. Flowers smaller, and more 

 numerous and crowded, and all remarkably turned to one side. Sepals very 

 email. Petals free, of a greenish white, Stjle long and nearly straight. 



The geographical range is nearly that of the common W., but it is more 

 local, and generally more northern or more alpine, being rarely found in 

 central and southern Europe out of the higher mountain-ranges. In Bri- 

 tain, only in Scotland and northern England, and very rarely in Ireland. 

 FL summer.
