[2] Endiandra introrsa is a tree reaching 40 metres tall with a trunk diameter of 90 cm.

[2] The base of the tree may be slightly buttressed and its trunk is cylindrical with some irregularities, bumps and depressions in the reddish brown bark.

Its leaves are simple, alternate or rarely opposite on the stem, ovate-lanceolate in shape, 5 to 9 cm long and 1.5 to 3.5 cm wide, and glossy green above but waxy greyish below with a long blunt leaf tip.

The fruit matures in January to March, being a large fleshy drupe, 3 to 6 cm in diameter and fairly round in shape, though often being broader than deep.

Endiandric acid C, isolated from the Endiandra introrsa tree, is reported to have better antibiotic activity than ampicillin.
