LEGUMINIFER. 59 
reddish tinge, has been supposed to bear some resemblance to a 
strawberry. The pod is small, completely 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 hilum. Plant pale-green, glabrous, or with a few 
scattered hairs, but with the upper portion of the calyx always 
downy. 
Strawberry-headed Trefoil.

Piate CCCLXIV. 
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. Flower-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 4 to 4 inch in diameter, becoming 3 to 3 
inch in fruit, when they have a general resemblance to those of T. 
fragiferum; but the inflated calyces are widest about or a little 
below the middle, so that the conical ends are separate from each
