156 LEGUMINOS^E. 



in a star-like manner. T. Molinerii (a variety of the 

 commonly cultivated T. incarnatum), T. Bocconi, and 

 T. strictum, were, until recently, considered to be con- 

 fined to the southern shores of continental Europe, but 

 are now known to be undoubtedly wild on the cliffs of 

 the extreme south coast of Cornwall. The first is a 

 short downy plant, with large soft heads of white flowers ; 

 T. Bocconi is a small plant, 2 4 inches high, with 

 roundish heads of white or pink flowers, the heads 

 always growing in pairs ; and T. strictum, which is of 

 about the same size, has globular heads of whitish 

 flowers, and is well distinguished by its 2-seeded 

 legumes, which are bulged near the summit, and by its 

 narrow-toothed leaflets, resembling in shape those of 

 Melilotus officindlis. (See "A Week at the Lizard," 

 p. 313.i 



*** Calyx inflated after flowering. 



11. T. fragiferum (Strawberry-headed Trefoil). 

 Heads globose, on long stalks ; calyx, after flowering, 

 membranaceous, downy, and remarkably inflated ; stern, 

 creeping. Meadows and pastures, often near the sea ; 

 not very common. This plant has somewhat of the 

 habit of T. repens; but the flowers are light purple, and 

 the heads of inflated calyces, which are often tinged with 

 pink, are not unlike the fruit from which the plant 

 receives its name. Fl. July, August. Perennial. 



**** Standard withering but not falling off, finally bend- 

 ing down and covering the legume ; flowers yellow. 



12. T. procumbens (Hop Trefoil). Flowers in dense, 

 roundish, oblong heads ; leaves stalked. Dry pastures ; 

 abundant. Not unlike Medicdgo lupulina in habit, 

 but at once distinguished when in fruit by the hop-like 

 heads of withered flowers. Specimens occur on the sea 

 coast, 2 3 inches high, with scanty foliage, and com- 

 paratively large flowers. Fl. June, July. Annual.
