MEADOWS, FIELDS AND PASTURES— SUMMER 235 



petals and upper sepals are arched, the lateral sepals spreading, 

 the Hp narrow and undivided, and the spur about twice as long as 

 the ovary. This flower is not uncommon in moist meadows, where 

 it blooms from June to August. A large variety, with greener 

 flowers, is sometimes known as the Great Butterfly Orchis. 



A considerable number of summer-flowering grasses are more 

 or less common in fields and meadows. We have not space for the 

 descriptions of these, but introduce illustrations of a few, including 

 the Cock's-foot Grass [Dactylis glomerata) which appears on Plate IV.
