Fraxinus L.


Ancient Latin name

Mostly deciduous trees (F. uhdei and F. griffithii are evergreen) or rarely shrubs. Winter buds black, brown or grey and with 1-2 pairs of thick bud scales. Branchlets flattened at the nodes. Leaves opposite (occasionally in 3s), compound, odd-pinnate. Flowers small, bisexual or unisexual in axillary or terminal clusters on the same or separate trees. Stamens 2. Fruit a 1-seeded 'key' (samara) with a long wing at the tip.

Grown in parks, gardens and as street trees for the relatively small size and attractive leaves in autumn.

Seed (which is short-lived); cultivars by budding and grafting, chiefly onto F. angustifolia although F. ornus has a less invasive root system and could be used more.

Some species are used for timber.

Trees with compound leaves and 1-seeded winged fruits.
