Description
Eucalyptus gregoryensis is a small tree or mallee that typically grows to a height of Шаблон:Convert and has a lignotuber. It has a semi-weeping habit and smooth powdery white bark that is pale pink when new. Young plants and coppice regrowth have broadly lance-shaped to egg-shaped, dull greyish green leaves, Шаблон:Cvt long and Шаблон:Cvt wide. The adult leaves are arranged alternately, lance-shaped or curved, the same dull green to grey-green leaves on both sides, Шаблон:Convert long and Шаблон:Convert wide with a base tapering to a petiole Шаблон:Cvt long. The flower buds are usually arranged in groups of three, sometimes seven, in leaf axils on an unbranched peduncle Шаблон:Cvt long, the individual buds sessile or on pedicels up to Шаблон:Cvt long. Mature buds are oval to spindle-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with a rounded to conical operculum. The flowers are white and the fruit is a woody, cup-shaped to hemispherical capsule Шаблон:Cvt long and Шаблон:Cvt wide, with the valves protruding above the rim.[1][2][3]
Taxonomy and naming
Eucalyptus gregoryensis was first formally described by the botanists Neville Walsh and David Edward Albrecht in 1998 in the journal Muelleria, although the name originally given was E. gregoriensis.[4] The type collection was made near a tributary of East Baines River in the Gregory National Park in 1996.[3]
The specific epithet is in reference to the Gregory National Park which was named for the explorer Augustus Charles Gregory who explored this area in 1855 and 1856.[2]
Distribution
The tree has a small range and is found in the Gregory National Park and the Victoria River Downs region in the top end of the Northern Territory where it is found up on the sandstone plateaus and cliffs over seasonal water courses.[2]
