Scientific name: Grevillea parviflora subsp. supplicans
Conservation status in NSW: Endangered
Commonwealth status: Not listed
Gazetted date: 24 Dec 1999
Profile last updated: 30 Jul 2019


A low shrub less than 1 m tall with arching branches, adopting a semi-prostrate form in exposed, shallow-soil situations. Branchlets are usually arranged on one side of the branch, with the leaves mostly held skywards. Leaves, 15 – 60 mm long, 0.6 – 2 (rarely up to 3) mm wide, are much shorter than in G. parviflora subsp. parviflora or G. linearifolia, and they are strongly curled under at the margins. Flowers usually white (though can be purple to pink) and are similar to those of G. linearifolia (with which it grows) and G. sericea; stipe of ovary 0.5 – 0.6 mm long. The species is differentiated from G. parviflora and G. linearifolia in Olde & Marriott (1995), p.80, and illustrated in fig. 58B as G. parviflora.


Has a very restricted known distribution (approximately 8 by 10 km) and is confined to the north-west of Sydney near Arcadia and the Maroota–Marramarra Creek area, in Hornsby and Baulkham Hills local government areas. It is known from only a few locations, one of which is in the southern portion of Marramarra National Park.

Habitat and ecology

  • Occurs in heathy woodland associations on skeletal sandy soils over massive sandstones. Local observations (by Douglas) do not support the description by Olde & Marriott (1995) of its habitat as "wet heath", rather that this taxon is strongly associated with clay-capped ridged of the Lucas Heights and Faulconbridge soil landscapes, but that it is quite restricted within these areas, suggesting it has a preference for yellow clays with periodically impeded drainage.
  • This plant may have an affinity with disturbance margins such as trail and road verges where soils are suitable and the availability of light due to clearing has promoted its growth.
  • May be associated with the margins of the Sydney Turpentine Ironbark Forest endangered ecological community and, to a greater extent, with Shale/Sandstone Transition Forest endangered ecological community.
  • Regenerates from seed and possibly also suckers.
  • Flowering is from August to November. Probably pollinated by insects.
