Eucalyptus umbrawarrensis, commonly known as the Umbrawarra gum,[1] is a small to medium-sized tree that is endemic to the Northern Territory. It has smooth, powdery white bark, narrow lance-shaped adult leaves, flower buds in groups of seven, white flowers and cup-shaped to barrel-shaped fruit.

Description

Eucalyptus umbrawarrensis is a tree that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has smooth powdery white bark, that is pale yellow to pale pink when new. Young plants and coppice regrowth have egg-shaped leaves that are arranged alternately, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are the same shade of glossy green on both sides, narrow lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide, tapering to a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils on an unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels about Шаблон:Cvt long. Mature buds are oval to spindle-shaped, Шаблон:Cvt long and about Шаблон:Cvt wide with a conical to beaked operculum that is about half as long as the floral cup. Flowering has been observed in January and October and the flowers are white. The fruit is a woody cup-shaped to barrel-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves near rim level.[1][2][3]
