Verticordia staminosa subsp. cylindracea var. cylindracea
Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth)
(EPBC Act). The species is eligible for listing as Endangered as, prior to the commencement of
the EPBC Act, it was listed as endangered under Schedule 1 of the Endangered Species
The main factors that are the cause of the species being eligible for listing in the Endangered
category are: there being less than 10,000 mature plants; a continuing decline in the number of
mature individuals; and, no subpopulation containing more than 1000 mature individuals.
The granite featherflower is also listed as Vulnerable (declared rare flora – extant) under the
Wildlife Conservation Act 1950 (Western Australia).
Granite featherflower is a small, much branched shrub with very narrow, more or less stalkless
leaves to 1.5 cm long. Its solitary yellow flowers have protruding stamens 6-7 mm long that are
bright red with yellow tips. Below these are yellow, very feathery sepals 5-6 mm long and two
bright red persistent bracts (Brown et al., 1998; Durell and Buehrig 2001).
Granite featherflower is endemic to south-west Western Australia, where it is known from eight
localities between Pingaring and east of Newdegate. It grows in seasonally wet shallow soil
pockets in crevices and on edges of exposed granite outcrops (Patten et al., 2004). A
generalised distribution map for granite featherflower is attached.
Fourteen populations have been described on water reserves, private land, roadside reserves,
and a small number of nature reserves. While 54% are within water reserves, these are not
managed for conservation. Just over one third (37%) of the total population is within nature
reserves managed for conservation (Department of Environment and Conservation 2014).
Three of the fourteen known populations (3, 6 and 7) increased between 2002 and 2011; while
four populations (1, 4, 5 and 9) declined. The remaining populations are stable. Overall the
population of granite featherflower has decreased by approximately one-third from
approximately 1500 in the late 1980s to 934 in 2010/11 (Department of Environment and
The following threats are identified in Patten et al., 2004 for granite featherflower:
Rabbits (Oryctolagus cuniculus) and kangaroos (Macropus spp) are present at populations
native plant seedlings, presumably including those of the granite featherflower thus affecting
recruitment. In areas where rabbits are present there appears to be little recruitment
suggesting that rabbits may be grazing on young seedlings.

Weeds are evident in many of the soil pockets occupied by granite featherflower and may be
threat from fire by providing fuel.
Recreation at Pingaring rock (Population 2) may be impacting on the population. Many
use (probably due to the proximity to the golf club). Trampling and soil disturbance may have
a negative effect on seedling recruitment and survival.
Water pipeline maintenance may impact on Population 9 which is located very close to a
Insecure tenure of private property populations may result in a change of land ownership
Fire is presumed to kill mature granite featherflower plants but is only a potential threat as
if there were a rise in quantity of grassy weeds the threat would become more significant.
The objective of recovery actions is to abate identified threats and maintain or enhance in situ
populations to ensure the long-term preservation of the taxon in the wild.
Ensure that owners and managers of land containing populations of granite featherflower
Declared Rare Flora status and EPBC threatened species listing of the taxon and the
associated legal responsibilities.
Work with owners and managers of land containing populations of granite featherflower to
Promote awareness of granite featherflower among land owners and managers and other
Collect and maintain ex situ storage of viable seed and cutting material collected from all
plants for possible future translocations.
Conduct further surveys to:
monitor the trend in population size and area of occupancy,
map critical habitat,
search for additional populations in areas of suitable habitat,

Monitor and report on the effectiveness of management actions – in particular long-term
Monitor the risk of fire becoming a threat to granite featherflower.
Conduct genetic research to investigate relationships between populations and
relationships/differences between granite featherflower and var. erecta to inform ex situ
management and potential translocations.
