4. _Trifolium hybridum_—Alsike Clover—has, perhaps, got its specific name from possessing appearances and qualities intermediate between the broad-leaf and the Dutch clovers. This species has been introduced from Sweden, and its growth, duration, and feeding qualities certainly entitle it to rank high, and more especially for growth on some of the stronger soils. In our experience we have not found it to possess such eminent perennial habits as have been claimed for it. It thins very much after the second year, and almost disappears in three years, unless it be renovated by being allowed to seed, when the new plants by no means attain to the vigour of their parents. 5. _Trifolium fragiferum_—Strawberry-headed Clover—has been named from the strawberry-like form which its head, of enlarged coloured calyxes, assumes after flowering; its flowers are pinkish, but otherwise of much the same size and form as those of the Dutch clover, which latter it again approaches in its creeping habit and form of its foliage. It is, however, here mentioned only to point out the difference of its habits and indications when compared with the Dutch or white clover. The strawberry trefoil is a native of cold wet pastures, such as bear the name of “hungry clays;” when present in quantity it is not to be confounded with Dutch clover, which would indicate a sound fertile soil. 6. _Trifolium repens_—White Dutch Clover—is a plant of very general cultivation, both at home and in the States, and in both of which quarters of the globe it maintains its character with great constancy. Dutch clover is a valuable pasture plant either in meadows or in seeds. In the former it is much increased by the addition of nitrates, soot, &c., with guano or superphosphate. As a plant, in seed mixtures, it is usually sown with other trifoliate plants and rye grasses, but if the soil be very light the Dutch clover may be increased or wholly used. 7. _Trifolium filiforme_—Small Yellow Clover—is one of the least of our small yellow-flowered division. It is a common native species occurring on the waysides, and has been brought into cultivation to only a limited extent, under the impression that its small herbage is suitable as a first bite for young stock, and hence the term “suckling clover” has been applied to it. It is of little value, and does not seem capable of being greatly improved. This species is often mistaken for the following, even by pretended botanists, but its lax head of smaller flowers will well distinguish it.
