74 THE FLORA OF THE ALPS 



The two commonest English species of Melick — M. 

 Lupulz'na, L., and minima, Desr. — are common in grassy 

 situations. Others have been introduced, including M. 

 sativa, L., Lucerne, with larger violet flowers. M. 

 falcata, L., a partially erect plant with violet-yellov/ 

 flowers and sickle-shaped legume, grows by road-sides 

 or in meadows. M. suffruticosa, Ram., a pubescent 

 plant, 2-8 in. high, with rather large yellow flowers, 

 round or obovate leaflets, and half-arrow-shaped stipules, 

 is found in rocky sub-alpine situations in Pyrenees.

Flowers small, yellow or white, in long axillary 

 racemes; filaments diadelphous; legume short, straight, 

 few-seeded. Not alpine. 



M. alba, Desr. {vulgaris, Willd.), with white flowers, 

 is a very common plant by road-sides. M. officinalisy 

 Desr. (arvensis, Wallr.), Melilot, and altissima, ThuilL, 

 with yellow flowers, are also widely distributed. 



10. Trifolium, L. 



Flowers usually in round umbel-like spikes or racemes, 

 containing honey ; petals united into a long tube ; legume

Most of the English species of Trefoil are Swiss ; there 

 are also some alpine species. 



A. Flowers purple or nearly white, changing to
