Genus: FraxinusView DescriptionDichotomous Key

Common Name: ASH
Habit: Shrub or tree; generally dioecious, often bisexual (in California). Stem: older bark smooth or becoming furrowed, generally gray; lenticels broadly elliptic; twigs cylindric to 4-angled, glabrous to hairy; developing short-shoot spurs. Leaf: simple or generally odd-pinnate, opposite, deciduous; petioles channeled, occasionally winged, hairy or not; if compound, leaflets (1)3--9, lanceolate to ovate or obovate, generally acute to acuminate at tip, entire or +- crenate-serrate, generally dark green adaxially, pale abaxially, thin to +- leathery in drier habitats, generally glabrous or with simple hairs abaxially or throughout, proximal opposite on rachis, stalked or not, terminal generally largest, stalk longer. Inflorescence: axillary, of clusters or long-branched panicles; flowers pedicelled. Flower: unisexual or bisexual; calyx 1--2 mm, shallowly +- 4-lobed to cut, persistent on fruit; petals 0, 2, or 4, free or fused to basal filaments. Staminate Flower: stamens 2(3); pistil vestigial. Pistillate Flower: stamens 0; style slender; ovules 2 per chamber. Fruit: achenes, winged, wings generally flat, extending to tip or base of seed-containing chamber. Seed: generally 1.
Species In Genus: +- 65 species: temperate. North America, Eurasia, tropical Asia. Etymology: (Latin: ancient name) Note: Fraxinus uhdei (Wenzig) Lingelsheim, Mexican ash, cultivated in western United States; similar to Fraxinus velutina, with +- larger leaves and leaflets, generally with stiff hairs to 0.5 mm bordering abaxial midvein and occasionally 2° veins abaxially (as occasionally in Fraxinus velutina), and +- larger fruit, but margins tapered to near base of fruit body; native northern Mexico to Honduras.
