In addition to the varieties of clover that have been discussed at some length in previous chapters are a number the value of which may be considerable to areas more or less local and limited. These include Sainfoin, Egyptian clover, Yellow clover, Sand lucerne, Japanese clover, Beggarweed and Seaside clover. Some of these, as Sainfoin and Buffalo clover, have been in the country for several years, and yet but little is known as to their behavior, except in very limited areas. Others, as Buffalo clover, native to the country are thought to have merit, and yet the degree of such merit does not appear to have been yet proved under cultivation. The three varieties but recently introduced are thought to have considerable promise for certain soils and climates to which they have special adaptation, but sufficient trial has not been given them to determine even approximately the measure of their worth to this country. These varieties will now be discussed, but for the reasons stated above it will be manifest that the discussion will of necessity be imperfect and fragmentary in character. SAINFOIN Sainfoin (_Onobrychis sativa_) is a perennial, leguminous, clover-like forage plant of the bean family. The word Sainfoin is equivalent to the French words for sound or wholesome hay. It is also frequently called Esparcette or Asperset, more especially in Germany. It is further known in England by the name Cock's Head, French Grass and Medick Vetchling. In some parts of France and Switzerland the name has been and probably is yet applied to lucerne (_Medicago sativa_). In its habit of growth it is more woody in the rootstock than clover and more branched. It also grows to a greater average height. The stems, which are covered with fine hairs, bear numerous leaves long and pinnate. The blossoms are numerous and of an attractive, pinkish color, brightening into a crimson tint. The seed pods are flattened from side to side and wrinkled, and are also sickle-shaped. They bear but one seed. The roots are strong and more or less branched. Sainfoin, as already intimated, is perennial in its habit of growth. When a field is once well set with the plants, it should continue to produce crops for a decade, but will eventually be crowded out with weeds or other grasses. It grows very early in the season, quite as early, if not earlier, than alfalfa, and continues to grow until autumn. The feeding value of sainfoin is much the same as that of alfalfa. It is much esteemed where it can be grown for the production of pasture, of soiling food, and also hay, valuable for enriching the land, through the medium of the roots, and also when the tops are plowed under as green manure.
