'''''Sorbus alnifolia''''' ([[syn.]] ''Aria alnifolia'') '''Alder-leafed Whitebeam''' or '''Korean Whitebeam''' is a species of [[whitebeam]] native to eastern [[Asia]] in [[China]], [[Korea]] and [[Japan]].<ref name=foc>Flora of China: [http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200011662 ''Sorbus alnifolia'']</ref> It is a medium-sized [[deciduous]] [[tree]] growing to 10–20 m tall with a trunk up to 30 cm diameter and grey [[bark]]; the crown is columnar or conic in young trees, becoming rounded with age, with branches angled upwards, and slender shoots. The [[leaf|leaves]] are green above, and thinly hairy with white hairs beneath, 5–10 cm long and 3–6 cm broad, simple, usually unlobed (but see varieties, below), broadest near the base, with serrated margins and an acute apex. The autumn colour is orange-pink to red. The [[flower]]s are 10–18 mm diameter, with five white petals and 20 yellowish-white stamens; they are produced in [[corymb]]s 4–8 cm diameter in late spring. The [[fruit]] is a globose [[pome]] 8–15 mm diameter, bright red, with a dimple at the apex; they are mature in mid autumn.<ref name=foc/><ref name=rushforth>Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins ISBN 0-00-220013-9.</ref> It is occasionally grown as an [[ornamental tree]] in northern Europe, primarily for its autumn colour. The [[cultivar]] 'Skyline' has been selected for its fastigiate growth.<ref name=rushforth/> {{Inc| Sorbus alnifolia, Koch (Micromeles alnifolia, Koehne. Pyrus Miyabei, Sarg.). Fig. 3652. Tree, to 60 ft., with upright branches: branchlets glabrous or slightly pubescent: lvs. ovate to elliptic-ovate, rounded at the base, short-acuminate, unequally serrate, glabrous above, glabrous or slightly pubescent beneath, on vigorous shoots sometimes densely pubescent, 2-4 in. long, with 6-10 pairs of veins: infl. loose, nearly glabrous, 6-12-fld.: fls. 1/3 – 1/2 in. across; ovary usually 2-celled: fr. sub-globose, 1/4 in. across, red with yellow. May; fr. in Sept., Oct. Cent. China, Manchuria, Korea, Japan. }} ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Varieties== There are three [[variety (biology)|varieties]]:<ref name=foc/> *''Sorbus alnifolia'' var. ''alnifolia''. Leaves unlobed. Throughout the range of the species. *''Sorbus alnifolia'' var. ''angulata'' S.B.Liang. Leaves weakly lobed; fruit oblong. Northeast China, Korea. *''Sorbus alnifolia'' var. ''lobulata'' Rehder. Leaves weakly lobed; fruit globose. Shandong Province. It has sometimes been placed in a separate genus of its own as ''Micromeles alnifolia'', differing from other whitebeams in the deciduous sepals on the fruit (persistent in other whitebeams), but genetic evidence places it close to ''[[Sorbus aria]]''.<ref name=rushforth/> ==Gallery== <gallery perrow=5> Image:Sorbus-alnifolia-habit.JPG|Specimen in cultivation, Denmark Image:Sorbus alnifolia 'Submollis' JPG1Ta.jpg|Sorbus alnifolia 'Submollis' in Arboretum Robert Lenoir - [[Rendeux]] ([[Belgium]]) Image:Sorbus alnifolia 'Submollis' JPG1La.jpg|Sorbus alnifolia 'Submollis' leaves in Autumn Image:SorbusAlnifoliaBark.jpg|Closeup of trunk. </gallery> ==References== <references/>    ==External links== *{{wplink}} {{stub}} __NOTOC__
