SA Census:
Census of South Australian plants (external link)     [genus Austrostipa]
Name derivation:
Austrostipa from the Latin 'auster' meaning south and the genus Stipa; referring to the genus being allied to Stipa but restricted to Australia. Puberula from the Latin 'puber' meaning downy and the diminutive '–ula' meaning slightly; referring to the plant which is wholly or partly covered with short hairs.  ​
Distribution:
Found in the southern part of South Australia, from the Nullarbor to the upper South-east, growing in a variety of habitats and soil types. Also found in Western Australia, New South Wales and Victoria.
Status:
Native. Common in South Australia. Rare in New South Wales and Victoria. Common in Western Australia.
Plant description:
Tufted perennia grass to 80 cm high, with erect unbranched culms and  pubescent nodes. Leaves pubescent, blade inrolled to 40 cm long and 2 mm wide. Inflorescence dense palnicle at first becoming lax and sparse to 30 cm long with green to slightly purplish glumes to 14 mm long, the lower 1–3 mm longer than upper. Flowering between September and December.

Key to this species: awn twice bent with coma, panicle contracted with short open branches, glumes narrow straight, callus long fine straight, lower glume 8-14 mm, lemma with apricot hairs and short hairs at apex appearing shorn, column scabrous, leaves pubescents

Fruit type:
Brown linear-elliptical lemma 6.5 mm long with a smooth surface covered in apricot colour hairs and a hair hair patch at the apex appearing shorn, coma to 0.7 mm, callus appear short hooked to 1.5 mm long, awn twice bent to 65 mm long with column scabrous.
Seed type:
Yellow-brown narrow ovoid grain to 4 mm long within the lemma.
Embryo type:
Lateral.
Seed collecting:
Use your hands to gently strip the seeds (lemma) off the mature fruiting spike, those that are turning apricot colour. Mature seeds will come off easily compare to the immature seeds that remain on the spike. Alternatively, you can break off the whole fruit spike to allow some of the seeds to mature further.
Seed cleaning:
Place the seeds/spike in a tray and leave to dry for two weeks. No further cleaning is required if only seed collected. If seed spikes collected, use hand to strip off the mature seeds. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
Viability of grass seeds could be very viable, depending on time of seed collections and seasonal conditions. From one collection, the seed viability was low, at 15%
