reddish tinge, has been supposed to hear some resemhlance to a 

 ptrawberry. The pod is small, comi)letely enclosed in the calyx, 

 ovoid, compressed, usually containing only one or two brownish 

 seeds, which are ovate - ovoid, compressed, truncate or slightly 

 notched at the liilum. Plant palc-grcen, glabrous, or with a few 

 scattered hairs, but with the upper portion of the calyx always 

 downy. 



Strawherry-headed Trefoil.

Rootstock none. Stems procumbent or ascending, not rooting 

 at the nodes. Leaves on short stalks; leaflets oblanceolate or 

 obovate, rounded or truncate at the apex, sharply denticulate on 

 the margins, with rather prominent veins. Stipules adnate for less 

 than half their length, half-ovate, with the free portion lanceolate, 

 gradually acuminated. Plower-heads all axillary, on stalks 

 exceeding their own length, and at length exceeding the leaves 

 from which they spring, solitary, globular-depressed, at length 

 spherical and rather dense. External bracts truncate, forming a 

 very small involucre, about one-tenth the length of the calyces. 

 Flowers indistinctly stalked. Calyx-tube in flower oblong, striate, 

 downy at the base of the upper teeth ; the 2 upper teeth setaceous, 

 longer than the calyx-tube, the 3 lower ones subulate, about equal 

 to it ; in fruit having the upper portion very much enlarged, be- 

 coming convex with a conical apex, reticulated, membranous, and 

 carrying forward the 2 divaricate projecting teeth so that they 

 much exceed the lower. Corolla more than twice as long as the 

 calyx, twisted round within it, so that the standard becomes the 

 lowest petal, shrivelling. Plant glabrous. 



By roadsides and in waste places. Appearing occasionally, 

 but not native or permanent in its stations. It has been found 

 abundantly in Lancashire, near Liverpool. I have myself seen it 

 plentifully at Gipsy Hill, Norwood. 



[England.] Annual. Summer. 



Stems numerous, 6 inches to 2 feet long. Peduncles variable 

 in length. Flower-heads 5 to ^ inch in diameter, becoming \ to -J 

 inch in fruit, when they have a general resemblance to those of T. 

 frai>itVrum; but the inflated calyces are widest about or a little 

 below the middle, so that the conical ends are separate from each
