Leaves similar to those of A. japonicum in general shape and lobing, but on the average somewhat smaller; petioles longer, 11⁄4 in. to 3 in. long, glabrous from the start, against downy at first and sometimes persistently so in A. japonicum; inflorescence and infrutescence pointing out more or less in the direction of the twig (pendulous in A. japonicum). Native of Japan. Although not described until 1911, there can be little doubt that this maple was cultivated by Messrs Veitch in their Coombe Wood nursery as early as 1888 as A. japonicum microphyllum. Certainly the plants cultivated in the USA under that name today are A. shirasawanum (Thomas J. Delendick, Brittonia Vol. 36, pp. 49–50 (1984)).

A. japonicum aureum Siesmayer
A. japonicum f. aureum Schwerin
A. japonicum 'Aureum' Hort.
Leaves greenish yellow when young, colouring red and orange in the autumn. Previously cultivated as A. japonicum ‘Aureum’, this has recently been shown to belong to A. shirasawanum (Delendick, op. cit., pp. 50–57). It was introduced to Britain by Messrs Veitch before 1881, and the cultivar name ‘Aureum’ would belong to the clone distributed by them. However, the fine tree portrayed in Vertrees’ work (p. 136), growing in D. M. Gelderen’s nursery (Firma C. Esveld) at Boskoop dates from the 1860s. Whether it is clonally the same as the Veitchian introduction is not yet certain.
