Interim Recovery Plan No. 150
Department of Conservation and Land Management, WA, 2003
This Interim Recovery Plan will operate from August 2003 to July 2008 but will remain in force until withdrawn or replaced. If the taxon is still ranked Critically Endangered after five years, the need to rewrite this IRP or to replace it with a full RP will be determined.
The following people have provided assistance and advice in the preparation of this Interim Recovery Plan:
Manager, DCLM's Threatened Flora Seed Centre
Horticulturalist, Botanic Garden and Parks Authority
Chief Executive Officer, Botanic Gardens and Parks Authority
Coordinator, Threatened Flora, DCLM's WA Threatened Species and Communities Unit
Thanks also to the W.A. Herbarium for providing access to Herbarium databases and specimen information.

Conostylis setigera - Tufts to 20 cm diam., stems short. Leaves flat, 8-36 cm long, 1-4 mm wide, striate, green with white hairs 0.7-4.5 mm long in several ranks on each margin, otherwise glabrous or rarely hairy. Inflorescence capitate, of 5-10 flowers; scape 4-20 cm long, usually shorter than leaves; scapose bracts 1 or 2, 0.9-4.5 cm long and leaf-like; bracts subtending inflorescence short. Perianth 10-15 mm long, yellow, suffused red with age, woolly-tomentose with branched hairs outside, shortly woolly inside; lobes 5-9 mm long. Stamens biseriate; filaments 0.2-1.5 mm long; anthers 2-3.5 mm long. Style 6-11.5 mm long, ± equal to stamens.
Conostylis setigera subsp. dasys - Leaves 15-30cm long, 1-2mm wide; lamina with shaggy hairs that are white on new growth, aging to black. A rare taxon with distinctive leaves.
Distribution and habitat. Confined to the Kojonup area of the southern wheatbelt of WA. Grows in gravelly loam and sand in Eucalyptus marginata and E. wandoo low open woodland and low heath.
Flowering period. October-November.
Etymology. From the Greek dasys (shaggy), in reference to the leaf hairs.
Conostylis setigera subsp. setigera - Leaves 5-36 cm long 1-4 mm wide; lamina glabrous or with sparse fine hairs; marginal hairs usually white.
Distribution and habitat. Widespread from Gillingarra south to Augusta and east to Cape Arid in southern WA. Grows in various soils and plant communities, from rich gravelly loam in forest to deep sand in woodland and heath. A variable taxon.
Flowering period. August-October.
Boscabel Conostylis (Conostylis setigera subsp. dasys) Interim Recovery Plan 2003-2008
In adopting this plan under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Minister for the Environment and Heritage has approved the following modifications.
The plan identifies a broad area as critical habitat, including buffer zones of a set distance around known populations. The Threatened Species Scientific Committee does not necessarily believe that such an area qualifies as habitat critical to the survival of the species, as defined in the EPBC Act.
For the purposes of reviewing this recovery plan under the EPBC Act, the Recovery Criteria are amended to read as follows:
Criteria for success: The number of individuals within populations and/or the number of populations have increased by 10% or more over the period of the plan's adoption under the EPBC Act.
Criteria for failure: The number of individuals within populations and/or the number of populations have decreased by 10% or more over the period of the plan's adoption under the EPBC Act.
