The bigleaf maple has the largest leaves of any maple, typically 15–30 cm (6–12 in) across with five deeply incised palmate lobes, with the largest running to 61 cm (24 in). [8] [9] The stems are 15–30 cm (6–12 in) long and contain milky sap. [6] In autumn, the leaves turn gold and yellow, contrasting against backdrops of evergreen ...
While both poison ivy and Acer negundo have compound leaves composed of three leaflets with ragged edges, Acer negundo exhibits an opposite branching pattern, as opposed to the alternating pattern of poison ivy. [16] Like poison ivy, Acer negundo is also a noted riparian species, and can often be found growing along riverbeds and in wet soils ...

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.
Shrivelling is a natural phenomenon where an object, with an attached sub-elastic covering, has its interior volume reduced in some way. The covering, which cannot contract any further, is then obliged to wrinkle and buckle , in order to preserve surface area while containing the lesser volume.
The leaves are broad and soft, 8–15 cm (3–6 in) long and 6–12 cm (2.5–4.5 in) broad, with three shallow forward-pointing lobes. [ 3 ] The fruit is a samara ; the seeds are about 27 mm (1.1 in) long and 11 mm (0.43 in) broad, with a wing angle of 145° and a conspicuously veined pedicel.
