• the bark is grey, pinkish to brownish, very variable, it cracks and peels off in various forms (plane-like bark type):
  • oval
  • rectangular
  • tongue-shaped
  • irregular large plates

• the arrangement of buds on the shoot on the twig is crosswise (directly) opposite
• the buds themselves are ovate, pointed, the terminal one is larger, the lateral ones stand out slightly from the twig
• the covering scales are two-colored – green with a brown margin

• shoots are straight, relatively thick, greenish-grey, later grey-brown
• leaf scars do not touch each other !

• the leaves are simple, 10 - 15 cm large, divided, palmately 5 - lobed to notched, individual lobes are blunt, notches are sharp !
• the leaves are roughly doubly serrate along the margin
• the upper side is wrinkled, glabrous
• the lower side is grey-green, tomentose when young
• the stem is 10 - 15 cm long

• it is a monosexual tree, flowers are bisexual, yellow-green, small
• flowers are grouped in hanging panicles 5 - 15 cm long
• it flowers in May after the leaves emerge

• the fruit is a winged dicotyledon fused mostly at an acute angle
• the wings are greenish to reddish, brown when ripe, 2 - 6 cm long
• the seeds are convex to round, they ripen in IX
• germination is 50 - 70%
• Seedling:
  • the cotyledons are smooth without transverse folds, ligulate, narrowed upwards, without a distinct rib with three parallel veins (unlike ash)

• in Southern and Central Europe, its occurrence is sporadic and rises from the north to the south of Europe
• in Slovakia from 240 m a.s.l. (foothills of the Little Carpathians) up to 1,240–1,560 m a.s.l. - to the upper forest border (e.g. Tomanová valley, Western Tatras)
• it grows as islands or as a mixed tree on ridges and scree in the ends of valleys and ravines together with European ash (Fraxinus excelsior), European elm (Ulmus glabra) and species of the linden genus (Tilia)

• it is a semi-shaded tree with high demands on soil and air humidity and the content of nutrients in the soil - mainly nitrogen

• it is a type of humid mountain climate of oceanic character

• it is an important land improvement tree
• it is valuable as a park tree, especially its colored cultivars:
  • yellow
  • red
  • yellow marbled (f. Leopoldii)
