PAPlLlONACEyE 3o3 



soil and a top-dressing from time to time is beneficial. 

 Easily propagated by division or seeds. It is distinguished 

 by a five-toothed, persistent calyx, which withers after 

 florescence, and its cymose heads of bloom. 



Jl. vulneraria*, variety alpestris (PI. XXIX). Dwarf 

 with leaves of five or eleven unequal leaflets, the terminal 

 one being very large; inflorescence definite, in simple or 

 compound capitules; corolla rosy-white (yellow in the 

 type). July-August. Alpine pastures. Not a garden variety. 



Jl. montana. Grassy plant; root-stock woody and run- 

 ning, spreading over the ground which it sometimes covers 

 for large spaces; leaves greyish, with silky hairs, many- 

 foliate; flowers rose, fragrant. June-August. Southern 

 Jura (Dole, Creux-du-Van, Saleve). 



Trifolium 



"Eng. : Trefoil, Clover; Fr. : Trefle ; Ger. : Klee. 



The only species really worth cultivation is alpinum, 

 which should be raised from seed as collected plants are 

 practically impossible to acclimatise. The generic charac- 

 teristics are interesting, as the genus includes the plant 

 commonly accepted as Shamrock (7". dubium). The calyx 

 has five long, sub-equal teeth; the corolla persists after 

 florescence, and the stamens are more or less adnate or 

 growing on to it; the leaves are divided into three leaflets; 

 the flowers are gathered into heads or cylindrical spikes. 



T. alpinum (PI. XXIX). The root-stock is short and 

 branched, so that large tufts are formed from which 

 spring glabrous, finely toothed leaves ; the flowers are 

 large and rosy, each carried on a very brief stalk and 

 massed, four to six in number, in a loose and globose head. 

 July-August. Alpine pastures, between j 200 and 25oom., 

 where it covers vast areas.
