308 DIADELPHIA— DECANDRIA. Trifolium. 



T. minus villosum, purpureo capite parvo echinato. Barrel. Ic. 

 t. 865. 



In dry, barren, sandy fields and pastures. 



Annual. June. 



Root slender, tuberculated. Stems several, procumbent, various 

 in length and luxuriance, round, branched, leafy, downy, often 

 zigzag. Leaflets obovate, sometimes acute, or somewhat point- 

 ed, finely toothed, downy. Stipulas ovate, broad, pointed, mem- 

 branous, ribbed. JFfeac/s some axillary, more terminal, ovate. 

 Cal. elliptical, tumid, with 10 deep furrows, and clothed with 

 fine soft hairs ; the teeth unequal, not half the length of the 

 tube, awl-shaped, green, spinous-pointed, fringed, somewhat 

 lengthened out after flowering, but always continuing straight. 

 Cor. pale rose-coloured, about as long as the calyx. Legume 

 membranous, with the rudiments of 2 seeds in an early state, 

 one of which only comes to perfection, and fills the tube of the 

 calyx, being thrice as large as the last. 



These three procumbent species oi Trifolium are clearly distinguish- 

 ed by their calyx-teeth, and the present is readily known by the 

 touch from T. scabrum. Having rudiments of 2 seeds in the 

 germen, it so far agrees with the suffocatum, hitherto arranged 

 near it, and forms some exception to the proper character of 

 this section ; but only one seed being perfected, it is best placed 

 with othevs so circumstanced, to which it is most closely allied. 



**** Calyx of the fruit infated, bladdery. 



15. ^ . fragiferum. Strawberry-headed Trefoil. 



Heads roundish. Calyx finally inflated, deflexed, with two 

 terminal teeth. Stems creeping.

Root tapering, its fibres beset with fleshy granulations. Herb 

 smooth, much resembling T. repens. Stems quite prostrate, 

 creeping extensively with several fibrous radicles, round, leafy, 

 many-flowered. Leaves on long spreading footstalks; leaflets 

 dark green, unspotted, obovate, or inversely heart-shaped, finely 

 toothed, striated with numerous transverse ribs. Stipula.^ large,
