Spec. Char., fyc. Leaves elliptic, somewhat obtuse, glutinous; axils of theveins naked on the under side. ( Willd. Sp. PI., iv. p. 335.) A large shrubor low tree, said to be a native of Hungary, Austria, and Turkey. It wasintroduced by Miller, in 1749, who is said to have raised it from seed ; and,if so, it must be a tolerably distinct kind; which, indeed, it appears tobe, though we are doubtful as to whether it is entitled to rank as a species.The largest plant of A. oblongata that we have heard of is in the GlasnevinBotanic Garden, where, in 1834, after being 30 years planted, it is 30 ft.high ; which confirms Willdenow’s conjecture, that, in a mild moist climate,it may become a tree. There are plants in the Horticultural Society’sGardens, and at Messrs. Loddiges’s.

It differs from the commonalder, in the leaves being pointed, in the leaves and the young w
