Verticordia densiflora

Verticordia densiflora, commonly known as compacted featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with small leaves, usually small pink and white flowers and which is widespread in the south-west of the state. It is a variable species and in his 1991 paper, Alex George formally described five varieties.

Description

Verticordia densiflora is an openly branched shrub which grows to a height of 2 m (7 ft). The leaves vary in shape from linear to egg-shaped and those nearer the flowers are usually broader than those on the lower part of the stem. [2]

The flowers are scented and arranged in round or corymb-like groups on erect stalks from 1.5 to 9 mm (0.06 to 0.4 in) long, depending on the variety. The floral cup is shaped like half a sphere, about 1.5 mm (0.06 in) long, smooth but hairy near its base. The sepals are pink, cream-coloured or pale yellow, sometimes white, 2–4 mm (0.08–0.2 in) long, with 3 lobes which have a fringe of coarse hairs. The petals are a similar colour to the sepals, 0.8–2.0 mm (0.03–0.08 in) long, egg-shaped many filaments on their ends. The style is 4–6 mm (0.16–0.24 in) long, extending beyond the petals and is curved and hairy. Flowering time differs, depending on the variety. [2]

Taxonomy and naming

Verticordia densiflora was first formally described by John Lindley in 1839 and the description was published in A Sketch of the Vegetation of the Swan River Colony . The type collection was made near the Swan River by James Drummond. [1] [3] The specific epithet (densiflora) "from the Latin densus (dense, crowded) and -florus (-flowered), in reference to the inflorescence." [2]

In a review of the genus in 1991, Alex George described five varieties of this species: [4]

George placed this species in subgenus Verticordia, section Corymbiformis along with V. polytricha , V. brownii , V. eriocephala and V. capillaris . [4]

Distribution and habitat

This verticordia occurs in a wide range of soils and vegetation associations in the south-west of Western Australia, with each variety having slightly differing requirements. [2]

Conservation

Pedunculata is the rarest of the five varieties and is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife [10] and as "Endangered" (EN) under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). [11] Variety rosteostella is classified as "Priority Three" [12] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [13] The three other varieties are classified as "not threatened". [14] [15] [16]

Use in horticulture

Most varieties and forms of this species have been grown and are hardy in gardens in a range of soils and growing conditions. Most can be propagated from cuttings and have horticultural merit. [2]
