Description

''Endiandra virens'' is a small tree with bright green leaves and large fruit. Usually seven to ten metres tall with a trunk diameter of 20 cm. The bark is pale, often grey or whitish grey. The bark is not smooth, with vertical ridges, lines and bumps, somewhat soft and corky. New branchlets green and smooth, new shoots with small hairs.


Leaves

The leaves are alternate, not toothed. 6 to 15 cm long, 2 to 3 cm wide. Oblong or
lanceolate The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular o ...
in shape. Leaves are narrow at both ends. Leaf stem 3 to 12 mm long. Glossy green above, duller below. The specific name ''virens'' refers to the bright green of the new leaves. The midrib, lateral veins and net veins are visible on both surfaces, raised and more evident under the leaf. Midrib raised under the leaf, somewhat depressed on the upper leaf surface.


Flowers and Fruit

Small cream flowers occur on

and Kin Kin represent a distinct species once named '' Endiandra lowiana'' by F. M. Bailey in 1892. These plants differ in leaf and bark character from the NSW populations and are similar to a less hairy Endiandra pubens while NSW plants are quite dissimilar to E. pubens. The type specimen of ''Endiandra lowiana'' is from Maroochie (Yandina), While the type for ''Endiandra virens'' is from the Clarence River see (APNI) thus should the QLD populations prove to be a distinct species they would be called ''Endiandra lowiana'' while NSW populations would retain the name ''Endiandra virens''. Genetic and more detailed morphological studies would help to clarify the status of these two taxa.
