Acer lobelii, known as Lobel's maple [2] [3] or L'Obel's maple[ citation needed ] is a rare maple tree native to southern Italy and the western Balkans. [4] [5] Synonyms include Acer platanoides subsp. lobelii [4] and Acer cappadocicum Gled. subsp. lobelii (Ten.) De Jong. [6]

Description

Acer lobelii is a medium-sized deciduous tree growing 20–25 metres (66–82 ft) tall with a narrow, erect crown. It is one of very few trees with a naturally fastigiate form. The bark is greenish-grey, smooth in young trees, becoming browner and shallowly furrowed in mature trees. The shoots are green covered by a thick glaucous blue-white wax at first, this wearing off within a year but the older shoots remaining green for several years.[ citation needed ]

The leaves are opposite, palmately lobed with five lobes, 6–12 centimetres (2.4–4.7 in) long and 6–15 centimetres (2.4–5.9 in) across; the lobes are entire or with one or two irregular teeth. The leaf stems bleed a milky latex when broken.[ citation needed ]

The flowers are in corymbs, yellow-green with five sepals 3–4 millimetres (0.12–0.16 in) long; flowering occurs in early spring. The fruit is a double samara with two winged seeds, the seeds are disc-shaped, strongly flattened, 6–11 millimetres (0.24–0.43 in) across and 2–3 millimetres (0.079–0.118 in) thick. The wings are 2.5 centimetres (0.98 in) long, widely spread, approaching a 180° angle. [5] [7] [8] [9]

Distribution

The species is rare and endangered in Italy, only occurring scattered in small groups in Italian sclerophyllous and semi-deciduous forests habitats. [10] It was widely considered endemic in southern Italy, [5] [8] [10] but is now also known in the western Balkans (former Yugoslavia), [4] a distribution fairly closely matched by Pinus heldreichii (Bosnian Pine).

It is closely related to, and in some respects intermediate between, Acer cappadocicum , from Asia, and Acer platanoides , from further north in Europe, hence Acer platanoides subsp. lobelii. The suggestion has been made that it could be a natural hybrid between them, but differences from both, notably the strongly glaucous bloom on the young shoots, make treatment as a distinct species more reasonable. [5] [8]

Cultivation and uses

Lobel's maple is grown as an ornamental tree in northern Europe, valued for its narrow crown which makes it suitable for planting in confined spaces. [8] Many of the trees in cultivation are grafted on Acer cappadocicum rootstocks, shown by the numerous root sprouts with Acer cappadocicum foliage. [5] [7]

The horticultural hybrid maple Acer × zoeschense is often cited as having Acer lobelii as one of its parents, [7] though more likely Acer cappadocicum. [8]
