Botanical description.

Genus subvelutina, F.v.M., Fragm. i, 31 (1858).

A tree attaining a considerable size with a rough persistent bark, as in A. intermedia, of which F. Mueller now (1866) thinks it may be a variety.

Foliage and young shoots glaucous or minutely pubescent, with often a few bristles on the flowering branches and inflorescence.

Leaves sessile or nearly so, ovate or ovate-lanceolate, mostly acute, all (excepting rarely the upper ones) cordate at the base with rounded auricles as in A. cordifolia, 2, to 4 inches long, the veins numerous, but not usually so much so nor so fine as in A. intermedia.

Flowers small, in loose corymbs, precisely as in A. intermedia.

Fruiting calyces 3 to 4 lines diameter. (B.Fl. iii, 184.)

With reference to the above referred to opinion Mueller at one time held as to the position of A. subvelutina with respect to A. intermedia, they are undoubtedly distinct, and Mueller realised that later.

A. subvelutina, F.v.M., differs from A. intermedia, DC., mainly in the sessile cordate or auriculate leaves, and in the minute hoary vesture covering the young branches and the inflorescence. In A. intermedia the vesture is present on the suckers only, and consists of rather stiff setæ with a scattered or less dense hoary vesture. The leaves of A. subvelutina. display remarkable variation in size, shape, and length of petiole. This is dealt with in an interesting illustrated article by Mr. C. T. Musson in “The Hawkesbury Agricultural College Journal” for July, 1906.
