Endiandra dichrophylla, commonly known as coach walnut, is a species of plant in the family Lauraceae native to Queensland, Australia. It is a rainforest tree, first described in 1892. It has a conservation status of least concern.

Description

Endiandra dichrophylla is a tree that may grow to about 20 m (66 ft) in height and 40 cm (16 in) diameter. The trunk is often buttressed and often produces coppice shoots. The leaves are hairless and measure about 10 cm (3.9 in) long and 4 cm (1.6 in) wide and have 7–11 pairs of lateral veins. The upperside is green, the underside is glaucous, and domatia are absent.

The inflorescence is a panicle emerging from the leaf axils. Flowers are cream to pale brown to pale green and they may be faintly scented; they have six tepals up to 2 mm (0.08 in) long. The fruit is an ellipsoid drupe, dark blue or black, about 2.8 cm (1.1 in) long and 1.2 cm (0.5 in) wide. It contains a single brown seed about 26 mm (1.0 in) long and 10 mm (0.4 in) wide.

Distribution

It occurs on the Atherton Tableland and nearby areas. It grows in mature rainforest at altitudes from 50 to 1,200 m (160 to 3,940 ft).

Conservation

This species was assessed by the International Union for Conservation of Nature (IUCN) in 2019 and found to be of least-concern. It is also rated as least-concern by the Queensland Government under its Nature Conservation Act. In its statement, the IUCN cites the lack of any perceived threat to the species, as well as a wide distribution and large population, as the basis for the assessment.
