Notes on Taxonomy and Nomenclature

Top of page
The name Fraxinus was first mentioned by the Roman natural scientist Pliny in the first century AD (Plinii Naturalis Historia). The Latin name excelsior means higher, and suggests that the common ash is one of the most magnificent trees of Europe. Confusion with F. angustifolia, frequent in southern France, is possible although its buds are brown and its leaves are more small-lanceolote.

Description

Top of page
General

A tree with a light crown, oval-shaped to spherical, with steeply angled branches, sparsely but regular branched on all sides. Monopodial growth. It can reach heights of more than 40 m at its maximum although 30 m is the norm. The average d.b.h. at maturity is 60-80 cm, although it may exceed 100 cm. A maximum d.b.h. of 190 cm at a height of 45 m was recorded by Mitchell (1978), diameters of more than 200 cm are given by Becker et al. (1982). The bole is straight, cylindrical with a slight tendency to eccentricity and can be clear of branches for 40-50% of the total height. Forking of shoots can occur after death of buds produced by late frost in spring or sudden onset of winter, after dry periods in plantations, or caused by attacks of insects or browsing by deer (Ningre et al., 1992; Duflot, 1995; Joyce et al., 1998).

Crown architecture and allometric relationships between stem development, crown dimension, foliage biomass and foliar density are described in Cluzeau et al. (1994), Goff and Ottorini (1996) and Ottorini et al. (1996). The root system is characterized as a sinker root system consisting of a taproot, and horizontally wide-spreading roots from which vertical or sinker roots develop (Kostler et al., 1968). The architecture of the root system can be modified, depending on soil conditions, from taproot type to sinker, superficial, and plate root systems without any vertical roots. The bark is olive-green and smooth in young trees but grey, rough and broad-furrowed on old trunks. It contains sclerified cells and relatively small but highly visible cork warts.

F. excelsior has sooty-black winter buds set in opposite pairs and smooth grey twigs. The leaves have 7-15 stalkless, broad or narrow, long-pointed leaflets, 5-12 cm x 1.5-4.5 cm, oblong-ovate to oblong-lanceolate, long-acuminate, tapering to a round base, sessile, crenate-serrulate, villous on the midrib and towards the base beneath.

Inflorescences, flowers and fruits

Panicles of purplish flowers develop from side buds in April before the leaves flush. The flowers are wind pollinated, trioecious, with male, female and bisexual flowers in different combinations on different trees (Mabberley, 1997). Petals and sepals are absent. Male flowers with two anthers, and female flowers with one ovary and two sterile anthers.

Fruit a samara (dry, indehiscent, winged, fruity), 2.5-5 cm long, 4-6 mm wide, lanceolate or broader towards the tip. Fructification starts at around 30 years but solitary trees may bear fruit much earlier. Mast years are usually every 2-3 years (Joyce et al., 1998). Ash seeds are flat, lanceolate and acuminate, with endosperm and flat embryo. They ripen on the tree during the period July to October and are shed by the wind over the winter and early spring. They germinate in the following spring after ripening in the warm for 6 months; a further 6 months in cool moist conditions are needed to break embryonic dormancy (Bartels, 1993). An account of natural dormancy breakage of ash can be found in Wagner (1996). The germination is epigeic. Cotyledons are tongue shaped.
