Cato2640 considers the culture of the willow as deserving to hold the third rank in estimation, and he gives it precedence to the cultivation of the olive, tillage for corn, or laying out land for pasture. It is not, however, because the willow is the only tree that produces withes; for they may be procured also from the broom, the poplar, the elm, the blood-red cornel, the birch, and the reed itself when split, or else the leaves of that plant, as we know to be the case in Liguria. The vine, also, will furnish them; the bramble, too, with the thorns removed, as well as the twisted hazel. It is a very singular thing, that a wood after it has been beaten and pounded should be found all the stronger for making withes, but such is a striking peculiarity that exists in the willow. The Greek red2641 willow is split for this purpose: while the willow2642 of Ameria is whiter but more brittle, for which reason it is used in an uncut state for tying. In Asia there are three varieties known of the willow; the black2643 willow, which is best adapted for making withes, the white willow, employed for various agricultural purposes, and a third, which is shorter than the others, and known as the helix.2644

With us, also, there is the same number of denominations given to as many varieties of the willow; one being known as the viminal or purple willow,2645 another as the nitelina,2646 from its resemblance to the colour of the nitela, thinner in the trunk than the preceding one, and the third as the Gallic2647 kind, being the thinnest of them all.
