Scientific name: Grevillea parviflora subsp. parviflora
12 Jun 1998
Profile last updated:
23 Feb 2016
A low spreading to erect shrub, usually less than a metre high. It ahs erect narrow leaves are 2-3.5 mm long and less than 1.3mm wide, with silky hairs on the underside and a short pointed tip. Leaf margins are curved back, or even rolled completely under. The small flowers are spider-like and clustered in groups of 6-12. The whole flower, both tube and protruding style, is white, aging to pinkinsh-red, with rusty-brown hairs on the outside of the corolla.
Sporadically distributed throughout the Sydney Basin with sizeable populations around Picton, Appin and Bargo (and possibly further south to the Moss Vale area) and in the Hunter at in the Cessnock - Kurri Kurri area (particularly Werakata NP). Separate populations are also known from Putty to Wyong and Lake Macquarie on the Central Coast.
Habitat and ecology
- Grows in sandy or light clay soils usually over thin shales, often with lateritic ironstone gravels and nodules. Sydney region occurrences are usually on Tertiary sands and alluvium, and soils edrived from the Mittagong Formation. Soil landscapes include Lucas Heights or Berkshire Park.
- Occurs in a range of vegetation types from heath and shrubby woodland to open forest. In Sydney it has been recorded from Shale Sandstone Transition Forest and in the Hunter in Kurri Sand Swamp Woodland. however, other communities occupied include Corymbia maculata - Angophora costata open forest in the Dooralong area, in Sydney Sandstone Ridgetop Woodland at Wedderburn and in Cooks River / Castlereagh Ironbark Forest at Kemps Creek.
- Associated species in the Kurri Sand Swamp Woodland include Eucalyptus parramattensis subsp. decadens, Angophora bakeri and E. fibrosa with Acacia elongata, Dillwynia parvifolia, Melaleuca thymifolia, Grevillea montana, Eragrostis brownii and Aristida vagans. In the Shale Sandstone Transition Forest associated species include Eucalyptus fibrosa, E. punctata, Corymbia gummifera, Pultenaea scabra var. biloba, Kunzea ambigua, Allocasuarina littoralis and Themeda australis. At sites with a stronger sandstone influence Eucalytpus sclerophylla, E. piperita, E. oblonga, Grevillea diffusa, G. mucronulata, Acacia suaveolens and Persoonia pinifolia are found. Despite the range of associated communities several understorey species which are common to several of the known sites of Grevillea parviflora subsp. parviflora can be identified and include Allocasuarina littoralis, Daviesia ulicifolia, Kunzea ambigua, Banksia spinulosa, Leptospermum trinervium, Melaleuca nodosa, Pimelea linifolia, Themeda australis, Entolasia stricta and Eragrostis brownii.
- G. parviflora subsp. parviflora has been recorded growing with several other threatened species including Acacia bynoeana (Heddon Greta), Dillwynia tenuifolia (Kemps Creek) and Persoonia
bargoensis (S. of Appin and at Bargo).
- Found over a range of altitudes from flat, low-lying areas to upper slopes and ridge crests. Hunter occurrences are usually 30-70m ASL, while the southern Sydney occurrences are typically at 200-300m ASL.
- Often occurs in open, slightly disturbed sites such as along tracks.
- Plants are capable of suckering from a rootstock and most populations demonstrate a degree of vegetative spread, particularly after disturbance such as fire. This can make counts of individual genets in a population very difficult, and stem counts are usually an acceptable means of assessment for management purposes.
- Flowering has been recorded between July to December as well as April-May. Flowers are insect-pollinated and seed dispersal is limited. Seedling recruitment after fire is uncommon, and most recovery after disturbance appears to be gesprouting from rhizomes.
- Competition from tick bush (Kunzea ambigua) can affect recruitment and recovery, including spread, following disturbance.

Activities to assist this species
- Ensure that personnel planning and undertaking road maintenance are able to identify the species and are aware of its habitat.
- Reinstate an appropriate fire regime (either restrict fire or undertake ecological burns as required).
- Ensure that this species is considered in all planning matters on land that contains or may contain populations
- Mark and fence off sites during development/road maintenance activities.
- Undertake weed control using methods that will not impact on populations of G. parviflora subsp. parviflora (avoid spraying in the vicinity of the plants and either hand pull weeds or cut and paint them).
- Ensure these populations and this habitat are protected.
- Mark known sites and potential habitat onto maps used for planning maintenance work.
- Conduct searches in potential habitat for new populations .
