A plant morphologist makes comparisons between structures in many different plants of the same or different species. Making such comparisons between similar structures in different plants tackles the question of why the structures are similar. It is quite likely that similar underlying causes of genetics, physiology, or response to the ...
Foliage and fruits; the fruit are an important characteristic for identification of this species. The wood is hard, yellowish-white to pale reddish, with the heartwood not distinct; it is used for furniture and woodturning. [13] Norway maple sits ambiguously between hard and soft maple with a Janka hardness of 1,010 lbf or 4,500 N.
We’ve been using paint dots for 25 years or so now, so some trees have several paint dots on them.” Pruning and treatment dots also give a heads-up to property owners near the trees.
Although some other maples (such as Acer griseum, Acer mandshuricum and the closely related A. cissifolium) have trifoliate leaves, only A. negundo regularly displays more than three leaflets. The leaflets are about 5–10 cm (2–4 in) long and 3–7 cm ( 1 + 1 ⁄ 4 – 2 + 3 ⁄ 4 in) wide with slightly serrate margins.
It is also occasionally confused for quaking aspen (Populus tremuloides), which has similar bark, but different leaves and buds.

[4] Betula populifolia lacks terminal buds.
