Italian maple (Eng), acirón (Spa), blada, oró (Cat), astigar, eihar italiarra (Baq).
The Italian maple can develop the appearance a small tree up to 7 m high, although most of the time it forms a dense, branching bush. The young twigs are hairy. The leaves are deciduous, opposite on the twigs, palmate, and up to 13 cm long with 5 shallow, rounded lobes. They are rather leathery, shiny on the upper side and more opaque on the underside; they do not secrete latex when cut. The greenish, inconspicuous flowers sprout in groups between March and April. The fruits, known as samaras, or keys, form in facing pairs where the wings forms an angle of 90° or less. Flora Iberica differentiates two general types:
Acer opalus Mill. subsp. granatense (Boiss.) Font Quer & Rothm. Usually the leaf blade is 2.5-8 cm long, with lobes deeper than half the blade, and a fairly hairy underside.
Acer opalus Mill. subsp. opalus. Usually the leaf blade is 3-13 cm long, with lobes shallow than half the blade. The underside of adult leaves is hairless or only hairy on the principal veins.
