Scientific name: Verticordia densiflora var. pedunculata

Common name: Long-stalked Featherflower

The Long-stalked Featherflower is conventionally accepted (CHAH 2012).

The Long-stalked Featherflower grows either as a straggly open plant or a bushy, multi-branched shrub, up to 60 cm tall and 60 cm in diameter. It has grayish-green, needle-like leaves on the lower part of the plant, and shorter, broader floral leaves. During summer, the plants are covered with small, dense to open, rounded groups of attractive pale to dark pink and white flowers. These fade to white as they age, continually changing and thus creating a slightly variegated appearance. The small flowers attract insects with their colour and honey scent (Brown et al. 1998).

The Long-stalked Featherflower is known from eight locations, south and east of Busselton and east of Manjimup, in the south-west of WA (Williams et al. 2001; WA DEC 2007). It occurs in the South-west Natural Resource Management region.

The Long-stalked Featherflower's extent of occurrence is 85 km² and its area of occupancy is approximately 0.05 km² (or approximately 4.7 hectares) (WA DEC 2007).

The Long-stalked Featherflower was discovered in 1981 during the Verticordia Reference Collection. A further subpopulation was discovered south of Busselton in 1984. In 1995, known subpopulations were surveyed and mapped, and a further five subpopulations were discovered between Dunsborough and Boyanup. In 1996, the subpopulation in Capel Nature Reserve was discovered. All subpopulations were surveyed in 2006 (WA DEC 2007).

The total subpopulation size for this variety is estimated to be 522 mature plants (WA DEC 2007). The subpopulation trend for this variety appears to be stable. Subopulation 1 was not found ten years after it was originally located, but is not regarded as extinct. Subpopulation 4 has also declined in number, but this is thought to be a natural fluctuation in numbers. The remaining subpopulations are stable and healthy (WA DEC 2007). The following table outlines subpopulation data (WA DEC 2007):

Subpopulation 1 and subpopulation 3e are located in nature reserves which are managed for the conservation of flora and fauna, but not specifically for the management of the Long-stalked Featherflower. Subpopulation 8 occurs on an unvested parkland reserve which is managed by the Busselton Naturalist's Club. The remaining subpopulations occur on Shire reserves or railway reserves (WA DEC 2007).

The Long-stalked Featherflower grows on light yellow or grey sands in low-lying, winter-wet areas. It has been recorded as occurring with Melaleuca viminea, Preiss's Paperbark (Melaleuca preissiana), Redheart (Eucalyptus decipiens), Flooded Gum (Eucalyptus rudis), Jarrah (Eucalyptus marginata), Marri (Corymbia calophylla), Balga Grass (Xanthorrhoea preissii), Western Australian Christmas Tree (Nuytsia floribunda), Hypocalymma angustifolium and Blueboy (Stirlingia latifolia) (WA DEC 2007). The variety is associated with the Shrublands on Southern Swan Coastal Plain Ironstones, which is listed as an endangered ecological community under the EPBC Act (Meissner & English 2005).

The Long-stalked Featherflower flowers from December to January (George 1991). Plants are killed by fire and the soil-stored seed germinates following fire or after soil disturbance (Brown et al. 1998).

The Long-stalked Featherflower is best surveyed in flower (December to January) and is distinguished from varieties of Compacted Featherflower (Verticordia densiflora) by the length of its longest flower stalks (5–9 mm long) and its slightly larger flowers, with fringed sepals up to 4 mm long, and fringed petals up to 2 mm long. In some subpopulations, this variety occurs with the Vasse Featherflower (Verticordia plumosa var. vassensis) which is a taller, upright shrub (Brown et al. 1998).

The Long-stalked Featherflower has a restricted distribution which is probably caused by specific ecological requirements. Its extent of occurrence is likely to have been diminished by extensive clearing. The long term survival of this variety is threatened by the extensive clearing, the degradation of road verges, the small areas of remnant vegetation and pressure for development in the Busselton region (WA DEC 2007).

Weeds, inappropriate fire regimes, Rabbit (Oryctolagus cuniculus) grazing, Kangaroo (Macropus spp.) grazing, dieback caused by Phytophthora cinnamomi, roadworks and firebreak maintenance threaten subpopulations in varying intensities. Weeds of greatest concern are grassy weeds and Patersonia spp. Frequent fire, too infrequent fire and fire during the flowering phase are all threats to the Long-stalked Featherflower (WA DEC 2007). 

Williams and colleagues (2001) list the following management actions:

  • survey the Ruabon - Tutunup Road to establish true extent of subpopulations
  • investigate the Kalgup location (Kalgup Road).

Management documents relevant to the Long-stalked Featherflower are at the start of the profile. Other relevant management documents include Meissner and English (2005) and Taylor and colleagues (2005).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
