A samara (/ s ə ˈ m ɑːr ə /, UK also: / ˈ s æ m ər-/) [1] is a winged achene, [2] a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit , and is indehiscent (not opening along a seam ).
The fruit is a four-winged elliptic samara, and has a sticky feel, reddish and turns yellowish towards the end of the season. The fruit typically measures 2.5–4 centimetres (0.98–1.57 in) long and 1.5–3 centimetres (0.59–1.18 in) across. [4] It bears fruits generally in January and fruiting lasts until November.
The yellow flowers are androdioecious, produced in small pendent corymbs in spring, the fruit being a paired samara with two winged seeds about 1 cm long with a 3 cm wing. [ 4 ] [ 6 ] [ 7 ] Cultivation and uses
The fruit is a double samara with two winged seeds. the seeds are disc-shaped, strongly flattened, 10–15 mm (3 ⁄ 8 – 5 ⁄ 8 in) across and 3 mm (1 ⁄ 8 in) thick. The wings are 3–5 cm (1 + 1 ⁄ 4 –2 in) long, widely spread, approaching a 180° angle. It typically produces a large quantity of viable seeds.
The fruit is a pair of samaras (winged seeds). The seeds are globose, 7–10 mm ( 9 ⁄ 32 – 13 ⁄ 32 in) in diameter, the wing 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long.

[2] [5] [6] The species is variable, and a number of varieties have been described: [2] Acer buergerianum var. buergerianum. Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Zhejiang.
The samara is comparatively small, < 10 mm long by 8 mm wide, the seed central. In trials in the UK, Triumph was found to be the first elm cultivar to flush in spring, and the first to shed its leaves in the fall, usually by early October. The tree grew poorly on thin soils over clay, which became very dry in summer, but excelled on floodplain ...
