__NOTOC__{{Plantbox

'''''Acer negundo''''' is a species of [[maple]] native to [[North America]]. '''Box Elder''', '''Boxelder Maple''', and '''Maple Ash''' are its most common names in the United States. Other variant names -- some of which are regional - include Ash Maple, Ash-leaf Maple, Black Ash, California Boxelder, Cutleaf Maple, Cut-leaved Maple, Negundo Maple, Red River Maple, Stinking Ash, Sugar Ash, Three-leaved Maple, and Western Boxelder.  In [[Canada]] it is commonly known as '''Manitoba Maple''' and occasionally as '''Elf Maple'''<ref>[http://cfs.nrcan.gc.ca/index/commtreesprairies/manitobamaple Community trees of the Prairie provinces - Canadian Forest Service<!-- Bot generated title -->]</ref>. In [[Russia]] it is called '''American Maple''' ({{lang-ru|американский клён}}) as well as Ash-leaf Maple ({{lang-ru|клён ясенелистный}}).

''Acer negundo'' is a small, usually fast-growing and fairly short-lived [[tree]] that grows up to 10-25 m tall, with a trunk diameter of 30-50&nbsp;cm, rarely up to 1 m diameter.  It often has several trunks and can form impenetrable thickets.<ref name="gelderen">van Gelderen, C.J. & van Gelderen, D.M. (1999). ''Maples for Gardens: A Color Encyclopedia''.</ref>
| growth_habit = ?  <!--- tree, shrub, herbaceous, vine, etc -->
+
 
| high = ?  <!--- 1m (3 ft) -->
+
The shoots are green, often with a whitish to pink or violet [[wax]]y coating when young.  Branches are smooth, somewhat brittle, and tend to retain a fresh green colour rather than forming a [[bark]] of dead, protective tissue.  The bark on its trunks is pale gray or light brown, deeply cleft into broad ridges, and scaly.<ref name=Keeler />
| wide =    <!--- 65cm (25 inches) -->
+
 
| origin = ?  <!--- Mexico, S America, S Europe, garden, etc -->
+
Unlike most other maples (which usually have [[leaf shape|simple]], [[leaf shape|palmate]]ly [[leaf shape|lobe]]d  [[leaf|leaves]]), ''Acer negundo'' has [[leaf shape|pinnate]]ly [[leaf shape|compound]] leaves that usually have three to seven leaflets.  Simple leaves are also occasionally present;  technically, these are single-leaflet compound leaves.  Although some other maples (such as [[Acer griseum|''A. griseum'']], ''[[Acer mandshuricum]]'' and the closely-related [[Acer cissifolium|''A. cissifolium'']]) have [[leaf shape|trifoliate]] leaves, only ''A. negundo'' regularly displays more than three leaflets.
| poisonous =    <!--- indicate parts of plants which are known/thought to be poisonous -->
+
 
| lifespan =    <!--- perennial, annual, etc -->
+
The leaflets are about 5-10&nbsp;cm long and 3-7&nbsp;cm wide with slightly serrate margins.  Leafs have a [[translucence|translucent]] light green colour and turn yellow in the [[Autumn|fall]].
| exposure = ?  <!--- full sun, part-sun, semi-shade, shade, indoors, bright filtered (you may list more than 1) -->
+
 
| water = ?  <!--- frequent, regular, moderate, drought tolerant, let dry then soak -->
+
The [[flower]]s are small and appear in early spring on drooping [[raceme]]s 10-20&nbsp;cm long. The [[seed]]s are paired [[Samara (fruit)|samara]]s, each seed slender, 1-2&nbsp;cm long, with a 2-3&nbsp;cm incurved wing; they drop in autumn or they may persist through winter.  Seeds are usually both prolific and [[fertile]].
| features =    <!--- flowers, fragrance, fruit, naturalizes, invasive -->
+
 
| hardiness =    <!--- frost sensitive, hardy, 5°C (40°F), etc -->
+
Unlike most other maples, ''A. negundo'' is fully [[plant sexuality|dioecious]] and both a "male" and "female" tree are needed for either to reproduce.
| bloom =    <!--- seasons which the plant blooms, if it is grown for its flowers -->
+
 
| usda_zones = ?  <!--- eg. 8-11 -->
+
* Winter buds: Terminal buds acute, an eighth of an inch long.  Lateral buds obtuse.  The inner scales enlarge when spring growth begins and often become an inch long before they fall.
| sunset_zones =    <!--- eg. 8, 9, 12-24, not available -->
+
* Flowers: April, before the leaves, yellow green; staminate flowers in clusters on slender hairy pedicels one and a half to two inches long.  Pistillate flowers in narrow drooping racemes.
| color = IndianRed
+
* Calyx: Yellow green; staminate flowers campanulate, five-lobed, hairy.  Pistillate flowers smaller, five-parted; disk rudimentary.
| image = Acnegundo.jpg
+
* Corolla: Wanting.
| image_width = 240px    <!--- leave as 240px if horizontal orientation photo, or change to 180px if vertical -->
+
* Stamens: Four to six, exserted; filaments slender, hairy; anthers linear, connective pointed.
| image_caption =    <!--- eg. Cultivated freesias -->
+
* Pistil: Ovary hairy, borne on disk, partly enclosed by calyx, two-celled, wing-margined.  Styles separate at base into two stigmatic lobes.
| regnum = Plantae
+
* Fruit: Maple keys, full size in early summer.  Borne in drooping racemes, pedicels one to two inches long.  Key an inch and a half to two inches long, nutlets diverging, wings straight or incurved.  September.  Seed half an inch long.  Cotyledons, thin, narrow.<ref name=Keeler />

Finally, note that a few botanists treat Boxelder Maple as its own distinct genus (''Negundo aceroides'') but this is not widely accepted.
