Verticordia rennieana explained

Verticordia rennieana is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an openly branched shrub with small, narrow, warty leaves and pink and silvery-white flowers in spring and summer.

Description

Verticordia rennieana is an openly branched shrub which grows to a height of NaNsigfig=1NaNsigfig=1 and NaNsigfig=1NaNsigfig=1 wide. Its new growth is whitish and the leaves are linear, NaNsigfig=1NaNsigfig=1 long and prominently warty.[1]

The flowers are scented and arranged in small groups near the ends of the branches, each flower on a stalk NaNsigfig=1NaNsigfig=1 long. The floral cup is hemispherical in shape, about 2sigfig=1NaNsigfig=1 long, with large green appendages forming a thick collar around the hypanthium. The sepals are pink and silvery-white, NaNsigfig=1NaNsigfig=1 long with 7 to 10 feathery lobes. The petals are spreading, pink to purple 4sigfig=1NaNsigfig=1 long, oval to almost round with a smooth edge. There are only 5 fertile stamens with groups of 3 staminodes between the stamens. The style is about 1sigfig=1NaNsigfig=1 long, thick, straight and hairy. Flowering time is from October to January.

Taxonomy and naming

Verticordia rennieana was first formally described by Ferdinand von Mueller and Ralph Tate in 1896 from a specimen collected by Richard Helms and the description was published in Transactions and proceedings and report, Royal Society of South Australia.[2] [3] The specific epithet (rennieana) honours Edward Henry Rennie.[4]

In his review of the genus in 1991, Alex George placed this species in subgenus Eperephes, section Integripetala along with V. helmsii, V. interioris, V. mirabilis and V. picta.[5]

Distribution and habitat

This verticordia is found in a broad area between Perenjori and Southern Cross where it grows in sand, sometimes with gravel or loam, often with other species of verticordia in the Avon Wheatbelt, Coolgardie and Yalgoo biogeographic regions.[6]

Conservation

Verticordia rennieana is classified as "Not Threatened" by the Western Australian Government Department of Parks and Wildlife.

Use in horticulture

Although this verticordia is rarely grown in gardens it is described as "a beautiful small shrub ... with honey-perfumed flowers". It is propagated from cuttings and requires a sunny position in well-drained soil.[7]
