Name derivation:
Centrolepis from the Greek 'kentron' meaning a spur and 'lepis' meaning scale; referring to the points on the bracts of Centrolepis fascicularis, the type specimen for the genus. Aristata from the Latin 'arista' meaning bristle or awn; alluding to the two long primary bracts.
Distribution:
Found from the southern Flinders Ranges, southern Eyre Peninsula to the lower South-east of South Australia, growing in moist microhabitats within woodland, open forest, heath and mallee mainly on sandy soils, often growing with other Centrolepis species. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Uncommon in New South Wales. Common in the other states.
Plant description:
Erect annual herb to 10 cm high, bright-green or becoming reddish after flowering. Leaves grass-like to 6 cm long and 1.6 mm wide, glabrous, shiny. Flower head flattened, oblong-ovoid, to 3 mm wide with two long opposite primary bracts,  somewhat gaping, with cartilaginous brown bases and leaf-like laminae, glabrous, the outer bract to 35 mm long, the inner one to 30 mm. Flowering between September and December.
Fruit type:
Brown ovoid head.
Embryo type:
Broad.
Seed collecting:
Collect whole plant that are starting to dry off and turning pale straw colour by picking then off with your fingers.
Seed cleaning:
Place the plants in a tray for 1-2 week to dry. Then rub the heads with your hands or a rubber bung to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds (soft) and frass (hard) usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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.
