BUTTONS-WOOD; a genus of the monogynia order, belonging to the tetrandrae clasps of plants. There is only one species, a native of North America, from whence the seeds are imported into Britain, and great numbers of the plants raised in the gardens of the curious. It seldom rises higher than five or six feet in this country. The branches come out opposite, sometimes by pairs, and at other times there are three arising at the same joint. The ends of the branches are terminated by spherical heads, about the size of a marble, each of which are composed of many small flowers, funnel-shaped, and of a whitish yellow colour, fastened to an axis that stands in the middle. They are propagated chiefly by seeds, though many are also raised from cuttings; they require a little shelter from cold when young, as well as from the sun in very hot weather; but in other respects are hardy enough. They thrive best in a moist soil.
