Acacia ramiflora was removed from the Environment Protection and Biodiversity Conservation Act 1999 list of threatened species on 23 May 2013.

Scientific name: Acacia ramiflora

This species is conventionally accepted as Acacia ramiflora (CHAH 2010).

Acacia ramiflora is a slender shrub to 3 m high with pendulous (drooping), smooth branchlets. Phyllodes (flattened stalk that acts as a leaf) are curved inwards, 8—12 cm long and 3—8 mm wide. Phyllodes narrow towards the base and gradually or abruptly narrow to a sharp end point to 2 mm long. Phyllodes are hairless, with three indistinct to slightly raised main nerves.

Inflorescences (flowerheads) are in groups 20—30 flowers with globular heads 4.5—5 mm in diameter on stalks 3—5 mm long. Seed pods are smooth, linear, and raised over seeds and slightly constricted between, and are approximately 9 cm long and 8 mm wide (Cowan & Maslin 2001; Pedley 1978, 1987; World Wide Wattle 2009). Seed pods may be covered in a thin white powdery coating (World Wide Wattle 2009).

Acacia ramiflora is known from north Queensland, with records of the species from (BRI Collection Records undated; Pedley 1978):

  • Torrens Creek - Pentland region in the Great Dividing Range
  • Robertson River area near the headwaters of the Gilbert River
  • Princess Hills area of the upper Herbert River
  • Newcastle Range near Paluma south of Ingham
  • Montgomery Range south of Gray Creek
  • Gregory Range, 80 km north-east of Hughenden on the road to Clyde Park
  • Warrigal Creek between Pentland and Longton
  • Gregory Development Road south of Belyando River.

There is no quantitative data on total population abundance, but herbarium records describe the species as 'common' at Warrigal Creek and 18 km south of the Belyando River in 2001; common 34 km east of Forsayth in 2005; 'scattered' on the Gorge Creek Track in Blackbraes National Park (NP) in 2002; and 'uncommon' at Greenvale south of Gray Creek in 2000. In 2005, three plants were seen at Mount Zero-Taravale Nature Refuge and two plants at a site south of the Paluma-Running River Road (BRI Collection Records undated).

This species occurs in White Mountains NP (Briggs & Leigh 1996), Blackbraes NP (QLD DERM 2012), Girringun (formerly Lumholtz) NP and Mount Zero-Taravale Nature Refuge (BRI Collection Records undated).

Acacia ramiflora grows in woodland on sandstone hills (Cowan & Maslin 2001; Pedley 1978, 1987), with one record from pebbly red earth in low open woodland of White's Ironbark (Eucalyptus whitei), and Triodia sp. (Pedley 1981). It is also known from Rustyjacket (Corymbia leichardtii) woodland with Spinifex (Triodia pungens) groundcover (Williams et al. 2004).

Plants have also been recorded within woodlands and open woodlands on sandstone and granite surfaces, with sandy or shallow rocky soils (including plateaus) (Williams et al. 2004). Williams and colleagues (2004) indicate that Acacia ramiflora is capable of sprouting after fire and that seedling recruitment can be triggered by fire, with a high proportion of seedling survival (BAAM 2011).

Flowering specimens have been collected in February and specimens with young fruit have been collected between July and August (Cowan & Maslin 2001; Pedley 1978, 1987). Seeding of the species is known to be triggered by fire, with adult plants also able to resprout post fire, in a similar manner to many other Acacias (Williams et al. 2004). Timing of fire is important, as climatic conditions, such as rainfall, effect seedling survival and need to occur after germination in order to achieve high reproductive success (Williams et al. 2004).

The species may be confused with Sim's Wattle (Acacia simsii) which has longer peduncles (stalks), narrower pods and arillate funicles (thickened covering at one end near the stalk of the seed) (World Wide Wattles 2009).
