27. n. 1—9. t.2D.f. 1,3,4. 



In meadows and pastures, very common. 



Perennial. May — September. 



Roots fibrous. Stems prostrate, creeping extensively with nume- 

 rous radicles, branched chiefly near their origin, round, smooth, 

 leafy, internally solid, by which character all the varieties are es- 

 sentially distinguished from T. hybridum of Linnaeus. Leaves on 

 long u]')nght footstalks ; leaflets on short, equal partial-stalks, in- 

 versely heart-shaped, or roundish, finely toothed, smooth, dark 

 green, variegated, mostly with a pale, curved, transverse stripe, 

 sometimes with dark purple, or blackish stains ; the under side 

 often reddish. Flower-stalks rising above the leaves, erect, or 

 ascending, angular, smooth, each bearing a dense, umbellate, 

 flattish head of numerous white flowers, turning brown as they 

 fade, the corolla remaining long in a withered state, enclosing 

 the little smooth oblong legume, containing 3 or 4 yellowish 

 seeds, till they fall off together. 



In a rich moist.soil the stems grow more upright, and the whole 

 herb k more luxuriant. Such a shape it usually assumes in low 

 ground, newly broken up, where this Trefoil is one of the first 

 spontaneous productions. As a valuable fodder in dry autumnal 

 months, it is well known, making an excellent bottom in pas- 

 tures. The Melilotus Parisiensis, &c. of Vaillant, t. 22. f 1, is 

 now judged to be a different species, and is named T. Vaillantii 

 by the writer of this, in Rees's Cyclopcedia, n. 23. 



4. T. suffocatum. Suffocated Trefoil. 



Heads sessile, lateral, roundish. Legume concealed, two- 

 seeded. Calyx nearly smooth, with lanceolate, acute, re- 

 curved teeth, longer than the corolla.
