Astrotricha linearis A.Cunn. ex Benth. APNI*
Description: Shrub to 1.5 m high; branchlets with a close non-floccose indumentum.
Leaves linear, 2–6.5 cm long, 1.0–1.5 mm wide; apex obtuse, sometimes with a very short blunt mucro; margins recurved to revolute; upper surface variably rough, the projections subconical and c. 0.2 mm long (sometimes these only), and/or granulate and < 0.1 mm high; lower surface with a dense woolly indumentum; subsessile or petiole to 5 mm long.
Inflorescences 3–12 cm long, several- to many-branched. Petals erect to spreading, whitish to pale cream-green.
Fruit not winged.
Distribution and occurrence: Grows in heath or dry sclerophyll woodland on sandstone, rhyolite, and limestone; south from Mudgee-Wellington district.
NSW subdivisions: NC, SC, CT, CWS
Other Australian states: Vic.
This is a variable taxon. It is likely that populations from the south of the State and Victoria irepresents a separate species, distinguishable by having large leaf projections only (no granules) which are situated on leaf surface wrinkles. More northerly populations (Beecroft Peninsula, Bungonia, and CWS) has smaller, more evenly distributed granules; this variant intergrades with A. species B near Currarong.
