Eucalyptus crispata, commonly known as the Yandanooka mallee, is a mallee that is native to Western Australia .[1]
Description
The spreading or erect mallee typically grows to a height of 3 to 7 metres (10 to 23 ft).[1] It has smooth grey bark on the branches and upper trunk with has rough peeling flakes of darker grey bark on the lower tree trunk.[2] It blooms between March and June producing yellow-cream flowers.[1]
It has blue-green juvenile leaves that become green and glossy as the plant matures. The adult leaves are narrow and sickle shaped and approximately 9 centimetres (3.5 in) in length with a width of 1.5 cm (0.59 in). Each inflorescence is composed of 13 flowers. The buds are around 1 cm (0.39 in) long and 1.5 mm (0.06 in) wide with a cylinder to cone shaped cap. Following flowering fruits form with a thin rim, a descending disc with three or four valves below the rim. The fruits contain pale grey to brown seeds.[2]
Taxonomy
The species was first formally described by the botanists Ian Brooker and Stephen Hopper in 1990 in the journal Nuytsia from a type specimen collected by the pair near Yandanooka in 1986. It belongs Eucalyptus belongs to Eucalyptus subgenus Symphyomyrtus section Bisectae subsection Glandulosae because it has bisected cotyledons and buds with a scarred operculum.[3] The species name crispata is from the latin word crispatus meaning curled in reference to the curled bark.[3]
Distribution
It is found in clumps among lateritic breakaways and hills in the western Wheatbelt region of Western Australia between Dandaragan, Carnamah and Three Springs where it grows in gravelly sandy-loam soils.[1] Overall the species has a range of approximately 80 kilometres (50 mi) with an estimated population of 85 plant in he wild confined to separate populations.[2] It is found in small stands among low mallee woodlands. Associated species include Eucalyptus arachnaea subsp. arachnaea, E. accedens, E. wandoo, Santalum acuminatum, Allocasuarina campestris and various species of Melaleuca.[2]
