Acacia melanoxylon, R. Br. Blackwood Acacia. Fig. 72. A good - sized evergreen tree of pyramidal form and dense foliage: phyll. oblanceolate to lanceolate, usually one edge straight, the other curved, 2 1/2 - 4 1/2in. long (average 3 1/2 in. long by 3/4in. wide), 3-6 parallel nerves, reticulately veined between; gland 1/6in. from base: fls. cream-color, 40-50 in a head, with peduncles over 1/2in. long, and in short racemes of 3-5 heads: pod reddish brown, with nerve-like margins, more or less twisted into shape of letter C or S, 3-5 in. long, 3/8in. wide; seed longitudinal, 1/8in. in length, encircled in double fold by a long red funicle which is very characteristic of the species, the seed hanging on the trees thus for months; pods ripe July-Nov. Fls. late Feb. and March. B.M. 16.59.—Its wood is but little inferior to black walnut for furniture-making and grillwork; it makes a good street tree in Calif, and as a fuel it is equal to hickory.
