Snakeskin Maple is a medium-sized deciduous tree grown mainly for its ornamental, green-striped bark, yet this charming plant also provide dramatic fall colors, as evidenced by these pictures. White Tigress Maple (Acer tegmentosum) is also called "snakebark maple".

According to eFloras.org - Flora of China, this taxon is a good candidate to be treated as a separate species instead of being listed as a subspecies of Aceri davidii, due chiefly to a differing number of flowers (10-15) per inflorescence, and its geographic distribution [2]. Indeed, the Morton Arboretum accession tag lists this plant as Acer grosseri.  USDA GRIN lists Acer grosseri as a synonym of A. davidii. [4]

Native to China, it is found in mixed forests at 1000-1600 m. elevation. [2]
