304 DIADELPHIA— DECANDRIA. Trifolium. 



On the east and south coasts of England, from Norfolk to Somer- 

 setshire, in various places. 



Annual. June, July. 



Root tapering. Herb clothed with fine, soft, more or less spi'ead- 

 ing, hairs. Stems spreading, often recumbent, a foot or more 

 in length, branched, leafy, round, or bluntly angular, striated. 

 Leaves alternate, except the uppermost pair ; the lower ones on 

 long slender/oo^s^a^Ars ; leaflets dark green, of a narrow obovate 

 figure ; obtuse, or notched, obscurely toothed towards the ex- 

 tremity, single-ribbed, hairy on both sides. Stipulas^ very long, 

 narrow, straight, taper-pointed, hairy. Spikes terminal, stalk- 

 ed, solitary, short, almost globular. Calyx with 10 strong ribs, 

 and deep intermediate furrows, hairy chiefly at the summit of 

 the tube ; its sharp teeth at first erect, awl-shaped, a little un- 

 equal, shorter than the corolla, becoming after flowering much 

 enlarged, leafy, three-ribbed, dark green, spreading, and still 

 more unequal, the lower one largest. Pet. pale red ; standard 

 a little the longest. Legume thin, roundish, in the tube of the 

 calyx. Seed, as far as I have seen, always solitary, roundish, 

 brown, protuberant at one edge where the radicle is lodged. 



This is one of that tribe of Trefoils distinguished by the teeth of 

 the calyx becoming remarkably leafy, and much dilated, as the 

 Jlower fades, and the seed ripens. In this it agrees with the fol- 

 lowing, but differs from pratense and its allies, as well as from 

 arvense, whose teeth, though permanent and rigid, do not become 

 leafy or dilated. T. maritimum makes a part of the food of cattle 

 in its native marshes, but has not been cultivated, or particu- 

 larly noticed, by the farmer. 



10. T. stellatum. Starry-headed Trefoil. 



Spikes hairy, roundish. Stipulas elliptical. Calyx-teeth 

 longer than the corolla ; after flowering dilated, leafy, 

 reticulated and spreading; tube closed. Leaflets in- 

 versely heart-shaped.
