Scientific Name: Conostylis seorsiflora subsp. trichophylla
Common Name: Hairy Mat Conostylis
The subspecies is conventionally accepted as Conostylis seorsiflora subsp. trichophylla (Hopper et al. 1987).
The Hairy Mat Conostylis is a rhizomatous (Paczkowska & Chapman 2000) prostrate, tufted, 34 cm in diameter mat-forming, or cushion-forming, perennial herb, very low-growing to only 8 cm high, with solitary, tubular, yellow flowers (1215 mm long) and flat, silvery-grey, densely hairy leaves up to 8 cm long. The plant branches and spreads by connected underground and aerial stems in a network up to 40 cm across (Brown et al. 1998; Durell & Buehrig 2001; WA DEC 2009i).
The Hairy Mat Conostylis has a restricted geographic range of approximately 68 km². It is known from three populations (one consisting of two subpopulations) in the Shires of Wickepin and Dumbleyung in the southern Wheatbelt of Western Australia (WA DEC 2009i). The two subpopulations are both located south-east of Tincurrin, one population is south-east of Lake Grace and the third is situated north-west of Kukerin (WA DEC 2009i). The subspecies is entirely located within the Avon Natural Resource Management Region of Western Australia (Western Australia Herbarium 2005).

The Hairy Mat Conostylis is in cultivation at Kings Park and Botanic Gardens, Perth, Western Australia (CHAH 2009).
The subspecies was surveyed between 1982 and 1999 (Durrel & Buehrig 2001; Graham & Mitchell 2000; WA DEC 2009i).

*= total for both subpopulations (WA DEC 2009i).
The total population of the Hairy Mat Conostylis is not known, but the three populations are thought to total approximately 1016 mature plants (WA DEC 2009i).
One population of the subspecies is located on a Water and Rivers Commission Reserve, south-west of Lake Grace (WA DEC 2009i).
The subspecies is found in seasonally wet, sandy loams in open mallee woodland, in areas of open scrub and also in more open areas amongst other herbaceous species. Associated species include White Gum (Eucalyptus wandoo), York Gum (E. loxophleba), Schauer Roadside Teatree (Leptospermum erubescens), Eremaea pauciflora, Red Tooth Brushes (Grevillea hookeriana), Manna Wattle (Acacia microbotrya), Melaleuca pentagona, M. urceolaris and Rock Sheoak (Allocasuarina huegeliana (WA DEH 2009i).
The age of sexual reproduction for the Hairy Mat Conostylis is unknown, however, other species of Conostylis, such as Prickly Conostylis (C. aculeata), C. serrulata, Bristly Cottonhead (C. setigera) and White Cottonhead (C. setosa), have ages of maturity (for plants in cultivation) of 34 years (Fairall 1970).
The Hairy Mat Conostylis flowers between OctoberNovember (Hopper et al. 1987; Paczkowska & Chapman 2000) and immature fruit has been recorded in November (WA DEC 2009i). The genus Conostylis, contains a mixture of insect and bird pollinated species (Holland et al. 1997b) however, the method of pollination of the Hairy Mat Conostylis is unknown.
The application of diluted and full strength smoke water has been found to substantially improve the germination of seed of four species of Conostylis (Tieu & Dixon 1990). It is likely that seed of the Hairy Mat Conostylis germinates following fire. Conostylis seeds germinate easily in cultivation if mature seed is used. The Botanic Gardens and Parks Authority have also grown the Hairy Mat Conostylis successfully from cutting material, but strike rates were variable between 1060% (WA DEC 2009i).
The proliferous (producing new individuals by budding) habit and solitary flowers distinguish the species (Conostylis seorsiflora), while the subspecies is distinguished by its hairy leaves, giving the Hairy Mat Conostylis a silvery-grey appearance (Durrell & Beuhrig 2001).
The main threats to the Hairy Mat Conostylis are (WA DEC 2009i):
- Firebreak maintenance is a threat to population number 2 as plants are located within 2 m of the maintenance track.
- Weed invasion is a threat to all Hairy Mat Conostylis populations.
- Grazing by the European Rabbit (Oryctolagus cuniculus), and/or kangaroos, threaten populations 1 and 2.
- Inappropriate fire regimes may adversely affect populations. Although its response to fire has not been documented, the subspecies is likely to require fire to stimulate the germination of soil stored seed. The current lack of recruitment is possibly due to the absence of fire.
- Senescence of mature plants potentially threatens all populations as seed longevity and recruitment success is unknown.
- Fragmentation of natural habitat has occurred due to clearing for agriculture. The subspecies is confined to relatively small areas of remnant natural vegetation subject to edge effects that include herbicide overspray, fertilisers and weed encroachment.
- Siltation is a minor threat to population 2 because it is located near a drain that periodically floods.
The Hairy Mat Conostylis (Conostylis seorsiflora subsp. trichophylla) Recovery Plan (WA DEC 2009i) recommends the following recovery actions for the subspecies:
- Coordinate the implementation of recovery actions.
- Liaise with relevant land managers.
- Monitor populations.
- Collect seed and other material to preserve genetic diversity.
- Extend and maintain fencing.
- Undertake weed control and follow-up with additional control if required.
- Obtain biological and ecological information.
- Seek security of tenure for subpopulation 1b.
- Develop and implement fire and disturbance trials.
- Develop and implement a fire management strategy.
- Promote awareness.
- Develop and implement a European Rabbit control strategy.
- Conduct further surveys.
- Map habitat critical to the survival of the subspecies.
- Develop and implement a translocation proposal.
- Review the need for further recovery actions.
The Declared Rare Flora in the Katanning District. Western Australian Wildlife Management Program No. 25 (Graham & Mitchell 2000) suggests the following management and research actions for the Katanning District population of the Hairy Mat Conostylis:
- Liaison with landowners and managers to ensure continuted survival of the Hairy Mat Conostylis as a priority subspecies.
- All populations within the District should be inspected annually to observe fluctuation in population numbers and to record any changes which may threaten survival.
- A network of permanent monitoring quadrants is to be established.
- Germplasm and seed collection, for ex situ storage, of Hairy Mat Conostylis.
- Intensive field survey of suitable habitas in the wild.
- Fire access track, or firebreaks, should be thoroughly searched for the subspecies, prior to construction.
- Investigate the taxonomy, genetic systems, population biology and ecology to determine the best means of protecting and managing populations of the Hairy Mat Conostylis.
- Investigate the subspecies' response to fire regimes.
- Investigate the subspecies' susceptibility to Phytophthora sp. and other introduced pathogens.
- Investigate the subspecies' reaction to increasing soil salinity.
The Declared Rare and Poorly Known Flora in The Narrogin District. Western Australian Wildlife Management Program No. 30 (Durrell & Buehrig 2001) suggests the following management and research requirements for the Tincurrin population of the Hairy Mat Conostylis:
- Survey the Tincurrin population during the flowering period annually to monitor the population.
- Regularly check the condition of the fence surrounding the population.
- Relocate the existing fence on the northern side to protect additional plants presently outside the fenced area.
- Monitor European Rabbit numbers and control as necessary.
- Control Veldt Grass (Ehrharta longiflora) incursion using herbicide.
