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. hyhridum of Linnaeus. Leaves on 

 long \\\W\^\\i 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 \\\\\i^ 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 is 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 Wdlant, t. 22. /. 1, is 

 now judged to be a different species, and is named T. i'aillantii 

 by the writer of this, in Uees's Cyclopa-dui, n. 23. 



4. T. sf/J/uca(////i. Suffocated Trefoil. 



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

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

 curved teeth*, longer tlian the corolla.
