Manna Ash (Fraxinus ornus) - samaras - October 2017
One of several Manna Ash trees located in the car park of the Digby Tesco store, Exeter, UK. === Manna Ash is a small, round-headed deciduous tree to 15m in height, with deep green, pinnate leaves and showy panicles of fragrant creamy-white flowers Sometimes planted as a street tree but also in parks. It is also known as flowering ash. Fraxinus ornus (manna ash or South European flowering ash) is a species of Fraxinus native to southern Europe and southwestern Asia, from Spain and Italy north to Austria, Poland and the Czech Republic, and east through the Balkans, Turkey, and western Syria to Lebanon and Armenia. The buds are pale pinkish-brown to grey-brown, with a dense covering of short grey hairs. The leaves are in opposite pairs, pinnate, broad, with a finely serrated and wavy margin. The autumn colour is variable, yellow to purplish. The flowers are produced in dense panicles 10–20 cm, long after the new leaves appear in late spring, each flower with four slender creamy white petals 5–6 mm (0.20–0.24 in) long; they are pollinated by insects. A sugary extract from the sap is extracted by making a cut in the bar. This was compared in late medieval times (attested by c.1400 with the biblical manna, giving rise to the English name of the tree). In fact, the sugar mannose and the sugar alcohol mannitol both derive their name from the extract. === Scientific classification Kingdom: Plantae (unranked): Angiosperms (unranked): Eudicots (unranked): Asterids Order: Lamiales Family: Oleaceae Genus: Fraxinus Species: F. ornus Binomial name Fraxinus ornus
