brads 3, at the base of each flower ; stems 

 ascending, herbaceous ; leaves narrow. 

 Common on heaths and dry pastures, 

 where it is highly ornamental during the 

 later summer months, with its starlike, 

 blue, pink, or white flowers. Fl. June to 

 August. Perennial. 



Besides the common form, P. vulgaris, 

 several more or less distinct varieties 

 have been distinguished, and classed as 

 species. Of these the more important 

 are as follows : P. oxyptera, with narrow 

 leaves ; flowers small, far apart ; inner 

 sepals narrow ; local. P. depressa inner 

 sepals broader than in the type ; common. 

 P. calcarea lower leaves tufted ; calyx- 

 wings blunt, with the veins scarcely netted ; has ceased to flower 

 almost before the common milkwort has commenced. P. amara 

 plant small ; wings narrow ; flowers pink ; confined to Cronkley 

 Fell, Yorkshire. P. Austriaca flowers larger, blue ; confined to 

 Kent.

 the claw and limb ; stamens equal in 

 number to the petals ; ovary 1 ; style 

 threadlike, 2, 3, or 4-cleft ; capsule 

 i-celled, 2, 3, or 4-valved ; seeds very
