Annual. June. 



Whole herb very smooth, with a tapering, branching, tuberculated 

 root. Stems quite prostrate, straight, slender, striated, but little 

 branched, from 3 to 12 inches long. Leaves rather distant, on 

 footstalks of various lengths ; leaflets obovate, abrupt, finely 

 toothed, veiny, sometimes marked with a pale transverse spot. 

 Stipulas ovate or oblong, membranous, ribbed, taper-pointed. 

 Heads axillary and terminal, solitary, sessile, hemispherical, or 

 nearly globular, many-flowered, quite smooth in every part. Cal. 

 bell-shaped, strongly furrowed, with ten ribs, pale or reddish 3 

 the teeth nearly equal, heart-shaped, pointed, reflexed, veiny, 

 green and leafy. Cor. longer than the calyx ; standard rose- 

 coloured, striated ; wings and keel shorter and paler. Legume 

 round, very small, with a solitary seed. 



This is neither a Scottish nor a Swiss plant. The small reflexed 

 cahjx-tecth, leafy in colour and texture, always quite smooth, 

 readily distinguish it from all our other species. 



14. T.striatujii. Soft Knotted Trefoil.

 cal, furrowed, hairy ; with straight bristle-shaped teeth.
