Description

Binghi Homoranthus is a bushy shrub 3 m tall and often 2 m wide, with thick, pale lime-green to dull blue-green leaves. The leaves are paired on the stem, with successive pairs at right angles to each other, and are 8 - 26 mm long, 1.5 - 2.5 mm thick and 0.5 - 1 mm wide with a curved tip. Pale yellow to green flowers, which later turn red, grow between stem and leaf. The flowers are relatively large for a Homoranthus, measuring about 12 mm long. Binghi Homoranthus can be distinguished from other Homoranthus species in the area by its larger size, thicker leaves and larger flowers.

Distribution

Restricted to the Torrington area south-west of Tenterfield.

Habitat and ecology

  • Flowers from November to January.
  • Associated with isolated granitic outcrops in the far north-eastern tablelands region of NSW. It grows within sandy soil pockets in open and exposed situations on and around the margins of the outcrops. The species appears to prefer heath and shrubland patches in shallow soils at altitudes of 700 to 950 m.
  • Associated species include Eucalyptus prava, Eucalyptus dealbata and Callitris endlicheri in the overstorey and Calytrix tetragona, Babingtonia odontocalyx, Leptospermum trinervium, Kunzea bracteolata, Leptospermum melaleucoides and Leucopogon novae-angliae in the shrub layer.
  • Homoranthus binghiensis is an obligate seeder and fruit is released in summer.
  • Only small numbers of seedlings have been observed in post-fire recruitment, and a very small soil-stored seed-bank detected. Studies of a related genus to Homoranthus, suggest that the seed-bank is relatively short-lived.
  • Homoranthus binghiensis is known from only a few populations, with an estimated total population size of a few hundred individuals. The species usually has a sparse distribution within smaller populations.
