Scientific name: Pimelea curviflora var. curviflora

Pimelea curviflora var. curviflora is an erect, open shrub (Threlfall 1983), generally growing to 40 cm high (Rye 1990), but sometimes up to 50 cm high (Fairley & Moore 2000; Rye 1990; Threlfall 1983). The leaves are 5–10 mm long, 2–4 mm wide, and elliptical (oval-like) to oblanceolate (broad across the mid section and tapering towards the stem) in shape. The lower surface of leaves is sparsely haired with coarse appressed (lying flat) or loosely appressed hairs. Flowers are dark red to yellow, 6–8 mm long, with long coarse appressed hairs and usually no stalk to note. They occur in clusters of 4–12 (PlantNET 2012).

Pimelea curviflora var. curviflora is confined to the coastal area of the Sydney and Illawarra regions of NSW (Fairley & Moore 2000; NSW OEH 2012e; Rye 1990; Threlfall 1983). Pimelea curviflora var. curviflora is known from approximately 20 locations from the coastal area of northern Sydney to Maroota in the north-west (NSW SC 1998). It is found in the Baulkham Hills, Blacktown, Hornsby, Parramatta and Warringah Local Government Areas (LGA) (NSW NPWS 1999ak). In 2011 a new population was detected at Croom Reserve near Albion Park in the Shellharbour LGA (NSW OEH 2012e). The species was formerly recorded around the Parramatta River and Port Jackson region including Five Dock, Bellevue Hill and Manly (NSW OEH 2012e).

Most Pimelea curviflora var. curviflora sites contain fewer than 100 individual plants. The two sites at Maroota have around 300 plants (NSW SC 1998).

Pimelea curviflora var. curviflora was recorded in Garigal National Park in 1992 and in Muogamarra Nature Reserve in 1971, but has not been recorded in these areas in subsequent surveys (NSW SC 1998).

Pimelea curviflora var. curviflora occurs on ridge tops and upper slopes in open forest and woodland on sandy soil derived from sandstone (NSW NPWS 1999ak; Rye 1990; Threlfall 1983), on shaley/lateritic soils (NSW NPWS 1999ak; NSW OEH 2012e) and shale/sandstone transition soils (NSW OEH 2012e). The population at Albion Park on the Illawara coastal plain occurs in Lowland Grassy Woodland habitat (NSW OEH 2012e). It often grows among dense grasses and sedges (CSIRO Plant Industry & Threatened Species Unit 1999) making it difficult to detect (NSW OEH 2012e).

Pimelea curviflora var. curviflora flowers may occur year round, but are mostly recorded October to January and occasionally until May (NSW OEH 2012e; Rye 1990). The flowers are bisexual or female (Threlfall 1983). The species can survive for some time without any foliage after fire or grazing, relying on energy reserves in its tuberous roots to support regrowth (CSIRO Plant Industry & Threatened Species Unit 1999). Seedlings have also been observed following fire (NSW OEH 2012e).

The scraggly habit of Pimelea curviflora var. curviflora makes it difficult to detect in areas with thick groundcover. The species can be identified year round, though the flowering period is the optimum survey period (NSW OEH 2012e).

The main identified threats to Pimelea curviflora var. curviflora include (NSW NPWS 1999ak; NSW OEH 2012e; NSW SC 1998):

  • habitat loss due to clearing for urban development
  • habitat degradation due to weed invasion, recreational activities, road and trail maintenance and bush rock removal
  • grazing by pest fauna including the European Rabbit (Oryctolagus cuniculus), the Goat (Capra hircus) and the Pig (Sus scrofa).

The NSW Office of the Environment and Heritage (2012) identify the following priority actions to assist in protection of the species:

  • manage weed infestation
  • introduce measures to prevent habitat degradation related to unrestricted access and/or trail maintenance
  • protect areas of known and potential habitat from clearing and further fragmentation.

Management plans relevant to Pimelea curviflora var. curviflora are at the start of the profile. Other relevant plants include the Garigal National Park management plan (NSW NPWS 1998c) and the Muogamarra Nature Reserve management plan (NSW NPWS 1998d).

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.
