The Fraxinus angustifolia or whipper ash ( Fraxinus angustifolia ) is a plant from the genus of the ash ( Fraxinus ). It is very similar to the common ash in appearance and ecology .
description
The narrow-leaved ash is a deciduous tree that reaches heights of growth of around 20 to 30 meters. The dark gray bark shatters with age through a dense network of fine cracks in ridges. The treetop is tall and irregular and very densely leafy. The thin, short and hanging branches have an olive-green to olive-brown bark . The buds are dark purple-brown.
The opposite constantly and often three of whorled arranged, structured in petiole and leaf blade leaves are 15 to 20 cm long and slender than that of the European ash . The leaf blade is pinnate unpaired and consists of seven to 13 slender leaflets . The leaflets are dark green at the top and lighter and bare at the bottom are 3 to 8 cm long and 1 to 2 cm wide.
The narrow-leaved ash is Andromonöz, which means that one specimen has both male and hermaphrodite inflorescences. It has racemose inflorescences and fruit stands. The wing nuts (samara) are elongated, elliptical in shape and 3 to 4 cm long.
The number of chromosomes is 2n = 46.
