Eucalyptus woodwardii, commonly known as lemon-flowered gum and also Woodward's blackbutt,[1] is a small tree or mallee that is endemic to Western Australia. The Noongar name for the tree is Gungurra.[2]
Description
The tree typically grows to a height of Script error: No such module "convert".[3] and a canopy that spreads to over Script error: No such module "convert"..[4] It has smooth, white, pink, greenish or light copper coloured bark that sheds in ribbons. Juvenile leaves are stalked, ovate to broad-lanceolate to elliptical, to 18 x 9 cm. Adult leaves have a disjunct arrangement and are stalked. The leaf blade has a broad-lanceolate shape, basally tapered and are about Script error: No such module "convert". in length and Script error: No such module "convert". wide. Leaves are dull, grey-green to glaucous and concolorous.[5] Lemon yellow flowers appear in late winter to late spring. Each axillary, simple conflorescence has three to seven flowered umbellasters on terete peduncles. The buds have a rostrate or urceolate appearance with a calyx calyptrate that sheds early. The fruit is bell or urceolate shaped that are about Script error: No such module "convert". long and Script error: No such module "convert". wide. Fruits have depressed discs and enclosed valves and contain red coloured seeds that are linear and cuboid.[5][6]
Taxonomy
Eucalyptus woodwardii was first formally described in 1910 by the botanist Joseph Maiden in the Journal and proceedings of the Natural History and Science Society of Western Australia.[7][8] The type specimens were collected by the surveyor Henry Deane in 1909 from along the Trans-Australian Railway line about Script error: No such module "convert". east of Kalgoorlie.[8]
Distribution
Lemon-flowered gum is found on flats and rises with a field distribution that is limited to east of Kalgoorlie in Western Australia in the Karonie area, and with sand or deep sandy loam.
Cultivation
The tree is a very popular ornamental in southern Australia due to its attractive, large, lemon-yellow flowers.[9] The cascades of yellow flowers, grey weeping foliage makes the drought tolerant tree suitable for many gardens. It is also frost tolerant and attracts bees and birds. Used as a privacy screening plant or a feature plant it has a medium growth rate and requires little pruning.[10] It is commercially available in seed or as tubestock.[10][4]
In the 1970s hybrids between this and coral gum (E. torquata) called Torwood had been developed.[11]
