Most species are deciduousand many are renowned for their autumn leaf colourbut a few in southern Asia and the Mediterranean region are evergreen. Most are shade-tolerant when young and are often riparian, understory, or pioneer species rather than climax overstory trees.

There are a few exceptions such as Sugar Maple. Many of the root systems are typically dense and fibrous, inhibiting the growth of other vegetation underneath them. A few species, notably Acer cappadocicumfrequently produce root sproutswhich can develop into clonal colonies.

The leaves in most species are palmate veined and lobed, with 3 to 9 rarely to 13 veins each leading to a lobe, one of which is central or apical.

A small number of species differ in having palmate compound, pinnate compound, pinnate veined or unlobed leaves. Several species, including Acer griseum paperbark mapleAcer mandshuricum Manchurian mapleAcer maximowiczianum Nikko maple and Acer triflorum three-flowered maplehave trifoliate leaves.

One species, Acer negundo box-elderhas pinnately compound leaves that may be simply trifoliate or may have five, seven, or rarely nine leaflets.

A few, such as Acer laevigatum Nepal maple and Acer carpinifolium hornbeam maplehave pinnately veined simple leaves.

Acer rubrum red maple flowers The flowers are regular, pentamerousand borne in racemescorymbsor umbels. The ovary is superior and has two carpelswhose wings elongate the flowers, making it easy to tell which flowers are female.

Maples flower in late winter or early springin most species with or just after the appearance of the leaves, but in some before the trees leaf out.

Keith Warren, at J. Frank Schmidt Nursery, Boring, Oregon, introduced the following two trees from this cross in Acer Norwegian Sunset™: its name reflects the similarity of the tree to a Norway Maple (A. platanoides), in . Organizational Structure and Strategic Leadership The business firm is no longer just a place where people come to work. For most of the employees, the firm confers on them that sense of belonging and identity—the firm has become their "village", their community.

Though individually small, the effect of an entire tree in flower can be striking in several species. Some maples are an early spring source of pollen and nectar for bees. The distinctive fruits are called samaras"maple keys", "helicopters", "whirlybirds" or "polynoses".

These seeds occur in distinctive pairs each containing one seed enclosed in a "nutlet" attached to a flattened wing of fibrous, papery tissue.

They are shaped to spin as they fall and to carry the seeds a considerable distance on the wind. People often call them "helicopters" due to the way that they spin as they fall. However, one tree can release hundreds of thousands of seeds at a time.

Depending on the species, the seeds can be small and green to orange and big with thicker seed pods.

The green seeds are released in pairs, sometimes with the stems still connected. The yellow seeds are released individually and almost always without the stems. Most species require stratification in order to germinateand some seeds can remain dormant in the soil for several years before germinating.

Recent classifications, including the Angiosperm Phylogeny Group system, favour inclusion in Sapindaceae. When put in family Sapindaceae, genus Acer is put in subfamily Hippocastanoideae. The genus is subdivided by its morphology into a multitude of sections and subsections.

In high concentrations, caterpillars, like the greenstriped mapleworm Dryocampa rubicundacan feed on the leaves so much that they cause temporary defoliation of host maple trees.

In horticultural applications a dimethoate spray will solve this. In the United States and Canada, all maple species are threatened by the Asian long-horned beetle Anoplophora glabripennis.With the release of the new Spin and Swift series, we will be updating the forums to accommodate the new naming structure.
