Eucalyptus megacornuta, also known as warted yate or warty yate, [2] is a species of Eucalyptus that is endemic to the south-west of Western Australia. [3]
The tree typically grows to a height of 4 to 12 metres (13 to 39 ft) [3] with a crown of up to about 6 m (20 ft) wide. E. megacornuta has the habit of a small tree or shrub with a smooth brown to grey-red and green trunk [2] and smooth bark over the length of the trunk and branches. The dull, green, thick and concolorous adult leaves have a disjunct arrangement. The leaf blade has lanceolate to elliptic shape that is basally tapered. [4]
It produces large yellow-green flowers that occur from July to October in the species' native range. [3] Each simple, axillary conflorescence is made up of three to seven flowered umbellasters on broadly flattened peduncles. [4] The fruits or capsules are clustered and sessile on a flattened peduncle. They have a campanulate shape with one prominent rib with many weak ribs. The capsules are 1.8 to 4 centimetres (0.7 to 1.6 in) in length and 2.2 to 2.5 cm (0.9 to 1.0 in) wide with three exserted valves. [5]
The species was formally described by botanist Charles Austin Gardner in 1942 [6] as part of the work Contributiones Florae Australiae Occidentalis as published in the Journal of the Royal Society of Western Australia. [7] The type specimen was collected by Gardner in 1935 near Ravensthorpe. [4] The specific epithet (megacornuta) means "large-horned", referring to the operculum. [8]
E. megacornuta is very similar in appearance to the closely related Beaufort Inlet Mallee ( Eucalyptus newbeyi ) and Burdett's mallee ( Eucalyptus burdettiana ). [9]
The species is found on hillsides and in creek beds along the south coast in the Great Southern and Goldfields-Esperance region of Western Australia between Albany and Hopetoun, [3] particularly in the Ravensthorpe Range, [2] where it grows in loamy alluvium soils over granite or laterite.
Eucalyptus megacornuta is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 [9] but as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [3]
The species is sold commercially in seed for or as tube stock, it grows well in full or par sun and is drought tolerant once established. A fast growing plant it can be used as an ornamental or privacy screening. The tree produces abundant nectar when it flowers so it is prized by apiarists and is a good bird attractor. The dried seed pods are also used in flower arrangements. [2]
