Eucalyptus woodwardii buds and flower

Eucalyptus woodwardii, commonly known as lemon-flowered gum and also Woodward's blackbutt, is a small tree or mallee that is endemic to Western Australia. The Noongar name for the tree is Gungurra.

Description

The tree typically grows to a height of Шаблон:Convert and a canopy that spreads to over Шаблон:Convert. 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 Шаблон:Convert in length and Шаблон:Convert wide. Leaves are dull, grey-green to glaucous and concolorous. 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 Шаблон:Convert long and Шаблон:Convert wide. Fruits have depressed discs and enclosed valves and contain red coloured seeds that are linear and cuboid.

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. The type specimens were collected by the surveyor Henry Deane in 1909 from along the Trans-Australian Railway line about Шаблон:Convert east of Kalgoorlie.

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. 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. It is commercially available in seed or as tubestock.

In the 1970s hybrids between this and coral gum (E. torquata) called Torwood had been developed.
