_Buffalo Clover (Fig. 247). (T. reflexum.)_--This is sometimes taken for a variety of the red clover, but only a glance is needed to distinguish it. While the head is perhaps an inch in diameter the flowerets are not directed upward and set close as in the red clover, but each floweret is on a little stalk, and is bent abruptly backward. The flowers are not pink. The standard is red, while the wings and keel are nearly white. The leaves are blunt at the tip. It grows in meadows in western New York and westward. This species is native to this country. _Alsike Clover. (T. hybridum.)_--This is a perennial and grows in low meadows and waste places from Nova Scotia to Idaho. It was introduced from Europe. It is especially valuable in wet meadows, where the red clover would be drowned. The blossoms of the alsike look like those of the white clover except that they are a little larger and are pink; but the long branching mostly upright stems are very different in habit from the creeping stems of the white clover; the blossoms are very fragrant. [Illustration: _Fig. 247. Three clovers, respectively, Buffalo, Yellow, and Rabbit-foot clover._] _The White Clover. (T. repens.)_--This beautiful little clover, whose leaves make a rug for our feet in every possible place, is well known to us all. It is the clover best beloved by honey-bees, and the person who does not know the distinct flavor of white clover honey has lost something out of life. While in hard soil the white clover lasts only two or three years, on rich, moist lands it is a true perennial. While it was probably a native in the northern part of America, yet it is truly cosmopolitan and may be found in almost all regions of the temperate zones. Very likely the common stock of it is an introduction from Europe. By many this is considered to be the original shamrock. _The Yellow, or Hop Clover (Fig. 247). (T. agrarium.)_--This friendly little plant, filling waste places with brilliant green leaves and small yellow flower-heads, is not considered a clover by those who are not observant. But if the flowerets in the small, dense heads are examined, they will be seen to resemble very closely those of the other clovers. The stems are many-branched and often grow a foot or more in height. The flowers are numerous, and on fading turn brown, and resemble the fruit of a pigmy hop vine, whence the name. Its leaves are much more pointed than those of the medics, with which it might be confused because of its yellow flowers. _Low Hop Clover, or Hop Trefoil. (T. procumbens.)_--This resembles the above species, except that it is smaller and also more spreading, and the stems and leaves are more downy. _The Least Hop Clover. (T. dubium.)_--This may be readily distinguished from the above species by the fact that its yellow flowerets occur from three to ten in a head. This is said by some to be the true shamrock, although the white clover is also called the shamrock.
