BLUE ASHâFrazmus quadrangulata Michaux This, the most slender of the North American Ashes, inhabits preferably hill- sides and river valleys and grows naturally from southern Ontario and Minnesota southward to east Tennessee, Alabama, and Arkansas. It reaches a maximum height of about 38 meters, thus rivaUng the White ash, but its trunk is not more than I meter thick. Its gray bark is i to 2 cm. thick, and splits up into large scales. The young twigs are 4-sided, whence the specific name, and at first, like the leaf-buds, red- dish velvety, but soon become smooth. All the 7 to II leaflets are stalked, hairy when they first imfold, and smooth, or somewhat hairy along the veins of the imder side when older; they are pointed and serrate with low teeth, and yellowish green. The flowers appear before the leaves in the spring, and differ from those 2 ^"~"<-$'^^^^^ °^ â¢Â°^^ other species in being perfect, ' that is, there are stamens and a pistil in â "^ â each flower; the calyx is minute and not toothed, and the 2 purple stamens are almost without filaments. The samaras are oblong to somewhat wedge-shaped, to 4 cm. long, i cm. wide or less, the thin blunt or notched wing decurrent on the margins of the flat striated fruit body to its base, and about twice its length. The Blue ash is usually a healthy tree, and well adapted to planting; its wood is light brownish yellow and hard, with a specific gravity of , and i
