Description

Banksia conferta subsp. conferta is a shrub growing to 4 m, irregular in shape, with bark roughly tessellated and grey in colour. Branchlets can be hairy to hairless and varying in colour from orange to red or brown. The leaves are whorled, elliptic to oval shaped, 3.5-12 cm long by 0.7-4 cm wide, with coarse short hairs on the upper surface and hairy to smooth on the lower surface. The flower clusters are cylindrical, 7-19 cm long and 5-6 cm wide at flowering. Individual flowers are yellowish-green to pinkish-brown in bud and golden when open, the styles are pale yellow and the old flowers may persist for several years. The seeds are egg-shaped 14-17 mm long; the seed body is crescent shaped, 8-9 mm long, 2-3.5 mm wide and smooth.

Distribution

In NSW, Banksia conferta subsp. conferta has a highly restricted geographic distribution. It is currently known only from a number of populations occupying about 23 ha in a small area of Coorabakh National Park, north west of Lansdowne on the Mid North Coast. Banksia conferta subsp. conferta is also known from the Lamington Plateau and the Glass House Mountains in Queensland, more than 400 km to the north.

Habitat and ecology

  • Detailed survey of the Coorabakh National Park population in 2009 estimated a total population of about 5,000 to 10,000 individuals with about 65% being mature plants,30% immature and 5% seedlings.
  • Adult plants are single-stemmed and likely to be killed by fire. Seeds are held within woody cones, and are mostly released after fire. Regeneration mainly occurs from canopy-stored seed released after fire although evidence based on population structure and fire history suggests that some seed leakage and regeneration can occur without fire.
  • Extreme fluctuations in population size may occur depending on the time between fires and establishment success of seedlings. Because of this populations are susceptible to declines or extinctions when fires recur at very short or very long intervals.
  • Banksia conferta subsp. conferta is found on exposed rocky slopes in well-drained skeletal soil derived from high-quartz conglomerate or occasionally trachyte. It occurs in comparatively low open forest with a dry sclerophyll understorey.
