3. Intermediate Winter green. Pyrola media, Swartz. 

 '(Fig. 637.) 

 (Eng. Bot. t. 1945.) 



Perhaps a mere variety of the com- 

 mon W., and sometimes passing almost 

 into the larger W. It differs 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. (Fig. 638.) 



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



Stock perennial, slightly creeping, re- 

 taining 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 orbi- 

 cular, 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 sta- Fig. 638.
