teeth ovate, acute, becoming leafy and veiny, and reflexed. Corolla 
small, pink, the vexillum striated. Legume membranous, mostly two 
seeded. 
Habitat.—Dry sandy pastures and waste places in the East and 
South of England. 
Annual; flowering in June. 
This species does not appear to have been found in elevated or cold 
situations. It is not unfrequent in the sandy pastures about Pisa or 
Rome, and is found in other parts of Italy, as well as in France. 
1l. Z. re'pens, Linn. (Fig. 1132.) White Trefoil, or Dutch Clover. 
Heads globose, axillary, on long peduncles ; pedicles after flowering, 
deflexed ; calyx smooth, its mouth naked, its teeth lanceolate, the 
two upper ones longest; leaflets obovate, or sub-cordate, and toothed ; 
stipules membranous, ovate, with a long point; stem creeping and 
rooting ; legume three or four seeded.

British Flora, ed. 4. vol. i. p. 274.—Lindley’s Synopsis, p. 81. 
Stem long, creeping, and putting out fibrous roots from the joints, 
smooth, striated, solid, and branched. Leaves alternate, the footstalks 
long, slender, channeled, erect, leaflets three, equal, on short stalks, 
roundish ovate, or obcordate, the margin finely toothed, the mid-rib 
prominent, and the lateral ones fine, parallel, straight, smooth, some- 
times reddish on the under side, the upper mostly with a pale 
transverse mark near the base, sometimes it is a dark purple or green. 
Stipules pale, thin, membranous, ovate, obtuse, with a linear point. 
Inflorescence axillary heads ot numerous crowded sub-umbellate 
flowers, the common stalk long, smooth, striated, the partial ones 
slender, downy, about as long as the calyx, erect in flower, curved 
downwards in seed. Calyx smooth, tubular, its teeth linear, lanceo- 
late, the two upper ones longest. Corolla white, persistent, becoming 
pale brown, and scarious. Zegume three or four seeded. 
Habitat—Meadows and pastures; common. 
Perennial ; flowering through the summer months. 
Curious varieties of this species are occasionally found in wet 
situations. Some have the partial footstalks much elongated, and the 
teeth of the calyx expanded into a leafy toothed segment; and it is 
not an unfrequent occurrence to find with these the legume enlarged 
and protruded beyond the calyx on a slender pedicle, and not unfre- 
quently the legume is expanded ; all are abortive in these varieties. 
The pedicles are all erect, and not recurved after flowering. 
This is one of the most valuable species of artificial grasses, both 
for fodder and pasture lands, especially in a light sandy or chalky 
soil. It is enabled by its long solid creeping stems to bear long 
droughts of summer, and from its putting out roots from every joint, 
it is enabled to bear continued cropping without injury, and its being
