Amur maple is treated either as a subspecies of Acer tataricum (Tatar maple), [3] or as a distinct species in its own right, Acer ginnala. [2] [4] [5] The glossy, deeply lobed leaves of subsp. ginnala distinguish it from subsp. tataricum, which has matt, unlobed or only shallowly lobed leaves; it is separated from subsp. tataricum by a roughly 3,000 km range gap across central Asia.

[ 6 ] [ 3 ] [ 7 ] The two differ conspicuously in the glossy, deeply lobed leaves of A. ginnala , compared to the matt, unlobed or only shallowly lobed leaves of A. tataricum , and are ...
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.

Acer spicatum is a deciduous shrub or small tree growing to 3–8 m (10–25 ft) tall, forming a spreading crown with a short trunk and slender branches. The leaves are opposite and simple, 6–10 cm (2 + 1 ⁄ 4 –4 in) long and wide, with 3 or 5 shallow broad lobes.
A single tree between 5 and 20 cm (2.0 and 7.9 in) in diameter can produce between 12,000 and 91,000 seeds in a season. A tree 30 cm (0.98 ft) in diameter was shown to produce nearly a million seeds. [8] Red maple produces one of the smallest seeds of any of the maples. [15]
