Fraxinus longicuspis Sieb. & Zucc.

Modern name

Fraxinus longicuspis Siebold & Zucc.


F. pubinervis Bl.; ? F. obovata Bl.; F. chinensis sens. Lingelsheim, in part

The following replaces the entry under F. pubinervis in the first impression of Volume II, page 225, and is an amplified version of the account of F. longicuspis that replaced it in the reprints.

A tree to 70 ft high; buds rusty tomentose; shoots quadrangular, clad with brown, crisped hairs when young. Leaves with two or three pairs of lateral leaflets, which are distinctly stalked and up to 4 in. long and 1[1/4] in. wide, broadly lanceolate or oblong-lanceolate, sometimes oblanceolate, long acuminate, they and the rachis crisped hairy when young, later glabrous, but sometimes permanently hairy beneath, dentate at the margin. Flowers without petals; calyx small, cup-shaped, four-toothed. Fruits oblanceolate, about 1[3/8] in. long.

Native of Japan, in the mountains of the main and southern islands. It belongs to the section Ornaster, in which the flowers are in panicles on short shoots as in section Ornus but lack petals. It was confused with F. sieboldiana by Lingelsheim, who placed that species under F. longicuspis as a variety, and in this he was followed by later authors. F. sieboldiana is a true ‘flowering ash’. F. longicuspis is only of botanical interest, and is allied to F. chinensis.

† F. japonica Bl. – Leaflets longer and wider than in F. longicuspis, acute or short-acuminate, with spreading hairs on the midrib beneath. Fruits larger, to 1[3/4] in. long. Native of the lowlands of the main island of Japan, and of Korea.
