280 SUMMER FLOWERS. 



** Corolla longer than the calyx. 



E. cinerea : shrub ; stems one foot or more high, bushy ; 

 leaves linear, pointed, three in a whorl, with clusters of small 

 leaves in their axils; flowers numerous, reddish purple, in 

 very showy, dense terminal racemes, the corolla ovoid. 

 Scotch Heather. Scotch, Irish, Welsh, and English moors, 

 covering immense tracts. Fl. July to October. 



E. Tetralix : shrub ; stems about a foot high, bushy at the 

 base, with short, erect flowering branches; leaves in fours, 

 linear, ciliate with short stiff hairs, the branches and upper 

 leaves clothed with a short, whitish down; flowers rose- 

 coloured, ovoid, forming little terminal clusters or close um- 

 bels. Boggy heaths. Fl. July, August. 



E. Mackaiana, a plant with shorter and broader leaves of 

 a darker green, from Cunnamara, in Ireland, which is closely 

 related to E. Tetralix , is sometimes regarded as distinct, some- 

 times as a mere variety. 



(184) Pyrola. WINTER-GREEN. 



P. minor : leaves stalked, broadly ovate or orbicular, entire 

 or slightly crenated, with a minute tooth or gland in each 

 notch; peduncle erect, 4-8 inches high, leafless; flowers 

 drooping, white or pinkish, in a short, loose raceme, the petals 

 ovate or orbicular, free, concave closing over the stamens. 

 Woods and moist shady places. Fl. July. 



P. rotundifolia is a somewhat larger plant, with larger and 

 whiter flowers, chiefly distinguished by having a long pro- 

 truding much curved style. 



P. media is intermediate in size, and is distinguished by 

 having a long protruding nearly straight style. 



Both the latter plants are found in woods and moist shady 

 places, but are more rare than P. minor.
