Eucalyptus microcorys, commonly known as tallowwood,[2] is a species of medium to tall tree that is endemic to eastern Australia.

It has rough, fibrous or string bark on the trunk and branches, lance-shaped to egg-shaped adult leaves, flower buds in groups of seven or nine, white to lemon-yellow flowers and conical fruit.

The flower buds are usually arranged at the ends of the branchlets, on a branched peduncle in groups of seven or nine, the peduncle 4–18 mm (0.16–0.71 in) long, the individual buds on pedicels 4–8 mm (0.16–0.31 in) long.

[2][3][4][5] Eucalyptus microcorys was first formally described in 1860 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by Hermann Beckler near the Hastings and Macleay Rivers.

[2] Tallowwood mainly grows in tall open forest on fertile soil on slopes and ridges and in valleys.
