Epithet from the Greek 'dendros' for tree and 'morphos' for form, in order to accentuate the difference with the other related species which are mallee. It is endemic to New South Wales, present on the plateaus and slopes of the Blue Mountains south of Budawang.

Botanical Description
It is a tree with a solitary trunk, absent lignotuber. Its bark is generally rough on the lower part of the trunk, compact gray or brown. Then smooth, white, cream or gray on the upper part. It also forms ribbons. Young reproductive trees may not have rough bark.

The adult leaves are alternate, petiole 0.6 to 1.5cm long, blade lanceolate to falcate. They are 7 to 12cm long and 1 to 2.5cm wide. The base is usually oblique. They are concolorous, glossy, sparsely reticulate. Intra marginal vein parallel and close to the margin.

The unbranched axillary inflorescence, on a peduncle from 0.6 to 1.5cm long, bears 7 to 11 buds per umbel, on pedicel 0.2 to 0.6cm long. At maturity, the buds are obovoid in shape, they are 0.5 to 0.6cm long and 0.2 to 0.3cm wide, smooth and sometimes warty. The scar is absent, the operculum is conical to rounded-apiculate. The stamens are irregularly flexed, the anthers are kidney-shaped to cordate, versatile and dorsifixed. The style is long, the stigma tapered, 3 to 4 locules. White flowering is recorded in January, June and December.

The pedicelled fruits (pedicel 0.1 to 0.5cm long), are cup-shaped or even barrel-shaped. They measure 0.7 to 1cm long and 0.7 to 1.1cm wide. 3 to 4 valves. The 1.5-2mm brown seeds are pyramidal or obliquely pyramidal. Smooth dorsal surface. Terminal hilum.
