==Description==
''Acer lobelii'' is a medium-sized deciduous tree growing to tall with a narrow, erect crown, one of very few trees with a naturally fastigiate form. The bark is greenish-grey, smooth in young trees, becoming browner and shallowly furrowed in mature trees. The shoots are green covered by a thick glaucous blue-white wax at first, this wearing off within a year but the older shoots remaining green for several years.
The leaves are opposite, palmately lobed with five lobes, long and across; the lobes are entire or with one or two irregular teeth. The leaf stems bleed a milky latex when broken.
The flowers are in corymbs, yellow-green with five sepals long; flowering occurs in early spring. The fruit is a double samara with two winged seeds, the seeds are disc-shaped, strongly flattened, across and thick. The wings are long, widely spread, approaching a 180° angle.〔
