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. Fruits are pale brown with three unequal awns much longer than the base. Seeds are long pale grain to 12mm long and lees than 1mm wide. Seed embryo type is lateral.

Seed collection and propagation

Collect seeds between October and December. 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. 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. From one collection, the seed viability was low, at 40%.
