Conservation status in NSW: Endangered
Commonwealth status: Not listed

Hibbertia stricta subsp. furcatula is a small shrub growing to 1.3 m in height and up to 70 cm wide. It is usually upright in habit, and is densely covered with hairs on the branchlets, flowers, and less densely on the leaves. Leaves are alternate, linear, 7 - 15 mm long, 0.5 - 0.8 mm wide, and are unevenly spaced and often appearing somewhat whorled. The subspecies is identified by fine forked fascicled hairs along the centre of the upper surface of the leaves. Flowers are solitary, mostly on short lateral branchlets growing from the end of the stalk. There are 6 to 8 stamens with 0.5 - 0.7 mm long filaments and the anthers are 2 - 3 mm long. There are two carpels that are 0.8 - 1 mm long.


Hibbertia stricta subsp. furcatula (Hibbertia sp. nov. 'Menai') is known to occur in two populations, one in the southern outskirts of Sydney, and one near Nowra on the mid-South Coast of NSW. The Southern Sydney population occurs on both sides of the Woronora River gorge, near Loftus and in Royal National Park. The southern population is mainly in the vicinity of Nowra.

Habitat and ecology

  • Habitat of the Southern Sydney population is broadly dry eucalypt forest and woodland. This population appears to occur mainly on upper slopes and above the Woronora River gorge escarpment, at or near the interface between the Lucas Heights soil landscape and Hawkesbury sandstone.
  • Toelken & Miller (2012) note that the species usually grows in 'gravelly loam or clay soil in heath under open woodland'.
  • Habitat of the South Coast population is poorly recorded, but appears to be dry sclerophyll forest or woodland associations in sandy soils over sandstone.
  • Hibbertia sp. nov. 'Menai' flowers in spring and summer ('September to January (February)' in Toelken & Miller (2012) yet also noted as July to about December (in NSW Flora online) and 'winter to summer' (Flora of the Sydney Region).
  • Its longevity, seed biology, and most aspects of its ecology are unknown, although in common with most species of Hibbertia it is probably pollinated primarily by bees.
  • It appears to propagate by seed, with no evidence to date of vegetative reproduction or regeneration.
