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. Mundula from the Latin 'mundus' meaning elegant; alluding to its attractive appearance.
Distribution:
Found in the southern part of South Australia, from the Eyre Peninsula to the lower South-east except on Kangaroo Island, growing on sandy to clay loams and limestone in grassland, heathland, shrubland and mallee. Also found in Western Australia and Victoria.
Status:
Native. Common in South Australia. Rare in Western Australia and Victoria.
Plant description:
Tufted perennial grass to 65 cm high with slender unbranched culm and pubescent nodes. Leaves smooth, sheath often purplish, with blade rigidly erect sturdy, tightly involute, to 20 cm long and less than 1 mm diameter. Inflorescence a sparse panicle to 18 cm long with purplish glumes 1to 17 mm long, the lower 1–4 mm longer than upper. Flowering between October and November.

Key to this species: awn twice bent with coma, panicle sparse contracted with short open branches, glumes narrow straight, callus long straight to 3 mm, culm slender to 1 mm, lower glume (12-17 mm), sometime associated with limestone

Fruit type:
Reddish-brown linear-elliptic lemma to 8 mm long, with a granular surface texture covered covered with white to golden hairs, coma obscure with hairs to 1.5 mm, callus long, straight to 3 mm long, awn twice bent to 80 mm long shortly pubescent, palea about 0.5 mm shorter than lemma with silky-hairy along the centre line.
Seed type:
Yellow-brown narrow ellipsoid grain 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 golden color. 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.
