Content
This deciduous tree reaches a height of 5–20 m with a trunk diameter of up to 50 cm. The leaves are opposing, 2.5–8 cm long (without a petiole 2–5 cm) and 3.5–6.5 cm wide, stiff, dark green shiny above and paler below, usually with three lobes; in old trees the leaves are elongated and with smooth edges, in young trees - wider and serrate edges. Flowers appear in spring, yellow-green, in a hanging panicle ; small, with five greenish sepals and five yellow-green petals about 2 mm long, with eight stamens. The fruit is a double lionfish with two seeds , each seed 4-7 mm in diameter, with a 15 mm wing; wings are elongated and often overlap. [3] [5] [6]
Varieties
The species is characterized by variability, the following subspecies are described: [3]
- Acer buergerianum subsp. buergerianum Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Zhejiang.
- Acer buergerianum subsp. formosanum ( Hayata ex Koidz. ) AEMurray & Lauener Sasaki. Taiwan (endemic).
- Acer buergerianum subsp. ningpoense ( Hance ) AEMurray
- Acer buergerianum var. jiujiangense zxyu jiangxi .
The leaves of young trees do not have lobes; they were first described as a subspecies of Acer trifidum hook. & Arn. var. integrifolium makino , but not currently stand out from view. [7] Sometimes leafless leaves appear on most trees along with normal three-blade leaves. [eight]
Widely used in temperate regions as an ornamental plant . It has long been introduced in Japan , where its name translates as "Chinese maple." [6] [9] Introduced in Europe and North America much later, in 1896 , and is now sometimes grown in parks and large gardens. [8] Adult specimens can be found in the Westbourth arboretum in England , the Esveld atcetum in Boscoop, the Netherlands, the Arnold arboretum in Boston and many other places. [five]
Bonsai
Instance at the
National Bonsai Fund ,
USA Three-section maple is a popular choice for creating bonsai and responds very well to the use of leaf reduction and pruning techniques. [five]
Varieties
Many interesting varieties have been developed , most of which bear Japanese names. Noteworthy are 'Goshiki Kaede' ('Goshiki Kaede') (a bright combination of pink and green), 'Kifu Nishiki' ('Kifu Nishiki') (rounded, almost leafless leaves), 'Mino Yatsubusa' ('Mino Yatsubusa') (dwarf with long narrow leaves), 'Mitsubato Kaede' ('Mitsubato Kaede') (distinguished by a cork- covered barrel) and 'Naruto' ('Naruto') (very rugged surface of the sheet).
