WESTERN BLACK WILLOW (_Salix lasiandra_) is a rather large tree when at its best, reaching a diameter of two feet or more, and a height of fifty, but in other parts of its range it rarely exceeds ten feet in height. It follows the western mountain ranges southward from British Columbia into California. The wood is soft, light, and brittle, and is used little if at all. Lyall willow (_Salix lasiandra lyalli_) is a well marked variety of this species and is a tree of respectable size. GLOSSYLEAF WILLOW (_Salix lucida_) is a far northern species which has its southern limit in Pennsylvania and Nebraska. It grows nearly to the Arctic circle. Trees twenty-five feet high and six or eight inches in diameter are the best this species affords. LONGLEAF WILLOW (_Salix fluviatilis_) is known also as sandbar willow, narrowleaf willow, shrub, white, red, and osier willow, and by still other names. It ranges from the Arctic circle to Mexico, reaching Maryland on the Atlantic coast, and California on the Pacific. In rare cases it is sixty feet high, and two in diameter, but it is usually less than twenty feet high. [Illustration] WAHOO [Illustration: WAHOO] WAHOO (_Evonymus Atropurpureus_) No one seems to know what the original meaning of the word wahoo was. It is applied to no fewer than six different trees in this country, four of them elms, one a basswood, and one the tree now under consideration. The generic name, _Evonymus_, appears to be an effort to put somebody’s seal of approval on the name, for it means in the Greek language “of good name.” It belongs to the family _Celastraceæ_, which means the staff family. Some designate members of this group as “Spindle trees,” because formerly in Europe the wood was employed for knitting needles, hooks for embroidering, spindles for spinning wheels, and the like. Unless the members of the family in Europe have wood quite different from that of the wahoo tree in this country, no adequate reason can be found for the use of the wood for spindles or staffs, because it is poor material for that purpose. It may be compared with basswood.
