Verticordia sieberi

Description

Verticordia sieberi is a shrub with a single main branch and which usually grows to a height of less than 1.5 m (5 ft). It is sometimes a compact, small shrub but may also be openly branched with the flowers held high above most of the foliage. The leaves are linear to elliptic, 2–8 mm (0.08–0.3 in) long and semi-circular in cross-section. [2]

The flowers are scented and arranged in round or corymb-like groups near the ends of the branches, each flower on an erect stalk 2–4 mm (0.08–0.2 in) long. The floral cup is about 2 mm (0.08 in) long, smooth and hairy. The sepals are spreading, 2–3 mm (0.08–0.1 in) long, white to deep pink with 5 to 7 feathery lobes. The petals are a similar colour to the petals, erect, about 2 mm (0.08 in) long, with short hairs around its edge. The style is 4–6 mm (0.16–0.24 in) long, curved and hairy near the tip. Flowering time is usually from November to April but can occur at other times, depending on weather conditions. [2]

Taxonomy and naming

Verticordia sieberi was first formally described by Johannes Conrad Schauer in 1841 from an unpublished description by Karl Diesing. Schauer's description was published in Monographia Myrtacearum Xerocarpicarum. [1] [3] The specific epithet (sieberi) honours the Austrian botanist Franz Sieber. [2]

In his review of the genus in 1991, Alex George placed this species in subgenus Verticordia, section Verticordia along with V. crebra , V. helichrysantha , V. plumosa , V. stenopetala , V. harveyi , V. pityrhops , and V. fimbrilepis . [4]

George described four varieties:

Distribution and habitat

This verticordia usually grows in sand, often in areas that are wet in winter, in heath and shrubland. It occurs along the south coast of Western Australia and inland near Frank Hann National Park and between Hyden and Lake King [2] in the Esperance Plains, Jarrah Forest, Coolgardie, and Mallee biogeographic region. [9]

Conservation

Verticordia sieberi var pachyphylla is classified as "Priority One" by the Western Australian Government Department of Parks and Wildlife, [10] meaning that it is known from only one or a few locations which are potentially at risk. [11] The other varieties are classified as "Not Threatened".

Use in horticulture

All the varieties of V. sieberi have proven difficult to propagate and establish in gardens and success in growing the species is rare. [2]

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

Verticordia plumosa, commonly known as plumed featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was the first species in the genus to be described, although initially given the name Chamelaucium plumosum. It is a shrub with linear leaves and rounded groups of scented pink, mauve or white flowers. Two varieties of this species have been declared as being "threatened".

Verticordia crebra, commonly known as Barrens featherflower, crowded featherflower or Twertup featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a sprawling shrub with crowded, cylinder-shaped leaves with small, yellow flowers that are almost hidden by the leaves but with a style which extends well beyond the petals. The plant looks superficially like a miniature pine tree.

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

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.

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

Verticordia habrantha, commonly known as hidden featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a slender shrub with short, leafy side-branches and long flowering stems with rounded heads of mostly white flowers. Its hairy sepals are mostly hidden by the round, unfringed petals, and as a result, the plant looks like shrubs in the genus Chamelaucium, to which it is closely related.

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

Verticordia helichrysantha, commonly known as coast featherflower or Barrens featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small, woody, open-branched shrub with crowded, linear leaves and small yellow flowers from May to September.

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.
