Verticordia cunninghamii, commonly known as tree featherflower or liandu, is a flowering plant in the myrtle family, Myrtaceae and is endemic to an area in the extreme north of Western Australia and the Northern Territory. It is a spindly shrub or small tree with narrow leaves and cream to white, sweetly scented, feathery flowers.

Description

Verticordia cunninghamii is a spindly to bushy, openly branched shrub or tree which grows to a height of up to 7 m (20 ft) and which has one to a few thick woody trunks at the base. The leaves are arranged in opposite pairs along the branches and are linear in shape, roughly round or three-sided in cross section, 10–20 mm (0.4–0.8 in) long, have a pointed tip and prominent oil glands. [2] [3]

The flowers are sweetly scented and arranged in rounded groups on stalks 6–9 mm (0.2–0.4 in) long. The floral cup is shaped like half a sphere, 1.5–2.0 mm (0.06–0.08 in) long, glabrous and slightly rough. The sepals are cream-coloured, 5–7 mm (0.2–0.3 in) long, with 2 hairy lobes. The petals are cream-coloured to white, egg-shaped, 3–4 mm (0.1–0.2 in) long, joined for about 1 mm (0.04 in) of that length and have uneven teeth around their top edge. The style is 5–7 mm (0.2–0.3 in) long, straight with hairs just below its tip. Flowering time is mainly from July to October, although it may vary, depending on rainfall. [2] [3]

Taxonomy and naming

Verticordia cunninghamii was first formally described by Johannes Conrad Schauer in 1843 and the description was published in Monographia Myrtacearum Xerocarpicarum. [1] [4] The specific epithet (cunninghamii) honours Allan Cunningham, who gathered the type collection at Roe River in the Kimberley region on the 14 December 1820. [2]

Verticordia cunninghamii is the type species for Verticordia sect. Tropica. This section includes two other outlying species of an otherwise West Australian genus, V. verticillata and V. decussata . [2]

Distribution and habitat

This verticordia has a widespread distribution in the north of Western Australia, including the Kimberley and in northern regions of the Northern Territory, including in Kakadu National Park. The species is usually associated with areas of seasonal flooding and watercourses, or along creeks, and has a preference for loam or gravel at exposed sandstone, growing in the white, or grey, or red sands there. [2]

Conservation

Verticordia cunninghamii is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife, [5]

Use in horticulture

Verticordia cunninghamii is a difficult plant to propagate and grow in cultivation and its requirements are not yet fully understood. [2]

<i>Verticordia verticillata</i> Species of flowering plant

Verticordia verticillata, commonly known as tropical featherflower or whorled-leaved featherflower is a flowering plant in the myrtle family, Myrtaceae and is endemic to an area in the north of the Northern Territory and Western Australia. It is a woody shrub or small tree with relatively long, linear leaves arranged in whorls, and with irregular groups of creamy-white flowers in spring.

Verticordia sect. Verticordia is one of eleven sections in the subgenus Verticordia. It includes eight species of plants in the genus Verticordia. Plants in this section are open to bushy shrubs up to 1 m (3 ft) tall with needle-like leaves, feather-like sepals and anthers opening by slanting pores. When Johannes Conrad Schauer described other subgenera in Verticordia, subgenus Verticordia became an autonym after Augustin de Candolle who described the genus in 1828. When Alex George reviewed the genus in 1991, he took the name of this section from that of the subgenus.

Verticordia sect. Chrysoma is one of seven sections in the subgenus Chrysoma. It includes four species of plants in the genus Verticordia. Plants in this section are small shrubs with small, bright yellow flowers which usually turn red as they age. They have sepals with fringed lobes and petals which have lobes arranged like the fingers of a hand. The subgenus Chrysoma was originally described in 1843 by Johannes Conrad Schauer and the description was published in Monographia Myrtacearum Xerocarpicarum. When Alex George reviewed the genus in 1991, he took the name of this section from that of the subgenus.

<i>Verticordia</i> Genus of flowering plants

Verticordia is a genus of more than 100 species of plants commonly known as featherflowers, in the myrtle family, Myrtaceae. They range in form from very small shrubs such as V. verticordina to trees like V. cunninghamii, some spindly, others dense and bushy, but the majority are woody shrubs up to 2.0 m (7 ft) tall. The flowers are variously described as "feathery", "woolly" or "hairy" and are found in most colours except blue. They often appear to be in rounded groups or spikes but in fact are always single, each flower borne on a separate stalk in a leaf axil. Each flower has five sepals and five petals all of a similar size with the sepals often having feathery or hairy lobes. There are usually ten stamens alternating with variously shaped staminodes. The style is simple, usually not extending beyond the petals and often has hairs near the tip. All but two species are found in Southwest Australia, the other two occurring in the Northern Territory.
