Eucalyptus × urnularis

Eucalyptus urnularis is a species of small tree that is endemic to the Northern Territory. It typically grows to a height of 6 m and has rough, flaky brownish bark on the trunk, smooth grey bark above. The adult leaves are arranged alternately, the same shade of green on both sides, broadly lance-shaped to curved, 120-180 mm long and 14-22 mm wide on a petiole 13-27 mm long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 5-17 mm long, the individual buds on pedicels 3-5 mm long. The fruit is an urn-shaped capsule 12-16 mm long and 10-14 mm wide.

Eucalyptus × urnularis was first formally described in 1985 by Denis John Carr and Stella Grace Maisie Carr from specimens collected "6.8 km north-west of the El Sharana mine" in 1973. The description was published in Eucalyptus 1 – New or little-known species of the Corymbosae. In Flora of Australia, George Chippendale described this as "a newly described taxon which has not been fully evaluated".
