Acer morrisonense

Acer morrisonense is an Asian species of maple found only in the mixed forests of eastern and southern Taiwan, at elevations of 1800 – 2200 m. The species is sometimes confused with another Taiwanese tree, Acer caudatifolium.

[1] Acer morrisonense is a tree growing to 20 m tall, with a smooth, yellowish-grey bark.

The branchlets are glabrous, bearing deciduous leaves with petioles 5–7 cm non-compound, the leaf blade suborbicular-ovate, 8-10 × 6-8  cm, papery, adaxially glabrous, 5-veined at the base which is nearly truncate or subcordate, the margin doubly serrate with coarse acute teeth, shallowly 5-lobed, to 1/5 width of blade.

The distinctive middle lobe is shortly ovate, the apex acuminate.

The flowers are racemose, 15 in number, and appear during March and April in Taiwan.
