Name derivation:
Aristida from the Latin 'arista' meaning awned, alluding to the awned lemma. Behriana named after Hermann H. Behr (1818-1904), a German-American doctor, entomologist and botanist, who collected in South Australia.
Distribution:
Found in dry areas of the Flinders and Mt Lofty Ranges. Also found in Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Uncommon in Queensland. Common in other states.
Plant description:
Short tufted perennial grass to 40cm tall, with leaf blades convolute up to 25cm long and 2mm wide. Inflorescence dense and contracted to 15cm long and almost as wide. Glumes unequal, the lower about two-thirds the length of the upper; 1-nerved, keels scabrid, the lower 7-12 mm long, aristulate, the upper 14-20 mm long, with an awn 1-2.5 mm long. Lemma 7-12 mm long (including the callus of 0.9-1 mm); convolute, smooth to sometimes scabrid apically. Awns 18-56 mm long, subequal, the laterals shorter by 1-5 mm, filiform.
Fruit type:
Pale brown with three unequal awns much longer than the base.
Seed type:
Long pale grain to 12mm long and lees than 1mm wide.
Embryo type:
Lateral.
Seed collecting:
Use hands to gently strip seeds off the mature seed spike that are turning straw colour. Mature seeds will come off easily. Alternatively, you can break off the whole seed spike.
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:
From one collection, the seed viability was low, at 40%.
