Scientific name: Grevillea floripendula
Common name: Drooping Grevillea
Other names: Ben Major Grevillea
Conventionally accepted as Grevillea floripendula (CHAH 2012). However, two forms of the species have been identified (Olde & Marriott 1995):
- Ben Major form, which has a sprawling mostly prostrate habit, growing up to 3 metres across, leaves that are shallowly divided, and flowers with a red tinge. This form is restricted to Ben Major State Forest.
- Musical Gully form, found north-west of Beaufort, grows to 1 metre tall and is shrubbier, with leaves more deeply divided and flowers that are variable in colour from dull purplish or pink-red to yellowish.
The Drooping Grevillea is a prostrate to spreading shrub growing up to 1 metre. Leaves are ovate (egg-shaped), 20—65 mm long and 15—40 mm wide, usually heavily divided (pinnatisect to pinnatifid), with 5—9 angular-obovate lobes, each ending in a spine. The upper surface is bright to dull green, smooth or slightly hairy, with short, recurved margins. The lower surface is light green with a sparse covering of curly to wavy hairs. Leaves often have a pungent odour (Carter & Walsh 2006j; Vic. DSE 2009g; Walsh & Entwisle 1996). Flower clusters are terminal (at the end of stems), usually pendulous (drooping) and 30—55 mm long. Flowers in each cluster are often turned to one side (secund), along the main stalk of the flower cluster (rachis) which is covered with short hairs. Individual flower stems are slender, wiry, and smooth to slightly hairy. Flowers are green to mauve and covered loosely with silky to woolly hairs externally, and mauve, maroon to blackish in colour internally. The pistil (female organ of a flower encompassing style, ovary and stigma) is 13.5—16 mm long, pale yellow, green-yellow, or pink to red. The ovary is borne on a stalk and densely covered in soft hairs. The style is hairy at the base, and the pollen presenter at the tip of the pistil is uneven in length. The fruits have longitudinal brown bands and are covered in small silky hairs (ABRS undated; Carter & Walsh 2006j; Vic. DSE 2009g; Walsh & Entwisle 1996).
The Drooping Grevillea is restricted to a small area north of Beaufort (approximately 160 km west of Melbourne); from Waterloo to Ben Major Forest (Carter & Walsh 2006j; Vic. DSE 2009g; Walsh & Entwisle 1996).
A 1997 census of records of the Drooping Grevillea identified 21 populations, with an estimated 4000 individuals. Abundance estimates at important populations in 1997 were (Vic DSE 2009g):
Ben Major Flora Reserve
- Big Hill Road 1 (375 plants, including many seedlings)
- Big Hill Road 2 (750 plants, including many seedlings)
- Amphitheatre Road (175 plants, including many seedlings)
- Grevillea Track (175 plants)
Roadsides (Shire of Pyrenees)
- Wildlife Road (750 plants recorded, including many seedlings)
- Sheisa Lane (750 plants, some seedlings observed with small proportion of the site burnt 2-3 years earlier)
Many other smaller populations also occur on roadsides. Four known roadside populations contain approximately 175 plants in each and eleven populations contain less than 50 plants each. Some of these sites may be important for the continued survival of the Drooping Grevillea due to their geographic range and genetic attributes (Carter & Walsh 2006j).
The Ben Major Flora Reserve in Ben Major State Forest contains four known populations.
Populations of the Drooping Grevillea occur in dry, open forest on shallow quartzitic soils (Walsh & Entwisle 1996). Associated overstorey species may include Long-leaved Box (Eucalyptus goniocalyx), Creswick Apple Box (E. aromaphloia) and Red Stringybark (E. macrorhyncha). Understorey species may include Narrow-leaved Bitter-pea (Daviesia leptophylla), Blue Flax-lily (Dianella revoluta), Common Heath (Epacris impressa), Silvertop Wallaby Grass (Joycea pallida), Small Mat-rush (Lomandra sororia) and/or Grey Tussock-grass (Poa sieberiana var. sieberiana) (Vic. DSE 2009g).
The Drooping Grevillea flowers October to December (ABRS undated). Little is known of the biology of the species. Many other related Grevillea species germinate or resprout from basal stems after fire, and anecdotal evidence suggests that this species is also an obligate seed regenerator (new individuals appearing after fire). Recruitment between fire events has been observed; suggesting some other disturbance event, such as digging by native fauna in populations of the Drooping Grevillea may cue germination. The species is likely to be bird-pollinated by Honeyeaters, such as the Eastern Spinebill (Acanthorhynchus tenuirostris) (Vic. DSE 2009g).
The Drooping Grevillea may be mistaken for a number of other Grevillea species. The Brisbane Range Grevillea (Grevillea steiglitziana) has a longer pistil at 15—20 mm than the Drooping Grevillea and a lower leaf surface covered in fine, silky hairs, that help distinguish the two species (ABRS undated; Walsh & Entwisle 1996). The Drooping Grevillea is distinguished from the Goldfields Grevillea (Grevillea dryophylla), as the latter has slender, wiry and glabrous (smooth) peduncles (ABRS undated; Walsh & Entwisle 1996). The species can also be distinguished from the Holly Grevillea (G. aquifolium) by the latter's denser covering of fine hairs on the lower leaf surface and a longer pistil (20 mm long) (ABRS undated). The Mount Cassel Grevillea (G. microstegia) has a stouter, usually shorter, and hairier peduncle and narrower, more acute leaf lobes than the Drooping Grevillea, whilst the Mount Cole Grevillea (G. montis-cole subsp. montis-cole) usually has a thicker, hairy peduncle and erect fruits (as opposed to the incurved fruits in the Drooping Grevillea) and pistils that are 26—27.5 mm long (ABRS undated).
The National Recovery Plan for the Ben Major Grevillea Grevillea floripendula (Vic. DSE 2009g) outlines specific objectives to assist in protection of the species. These are:
- Acquire accurate information for conservation status assessments.
- Identify habitat that is critical, common or potential.
- Ensure that all populations and their habitat are protected and managed appropriately.
- Manage threats to populations.
- Identify key biological functions.
- Determine the growth rates and viability of populations.
- Establish populations in cultivation.
- Build community support for conservation.
Management documents for the Drooping Grevillea are at the start of the profile.
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
