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. Fascicularis from Latin meaning clustered or grouped together in bundles.
Distribution:
Found on the lower Eyre Peninsula, Kangaroo Island, southern Mount Lofty Ranges and the lower South-east, growing on margins of swamps and in moist microhabitats. Also found in Western Australia, Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Uncommon in South Australia. Rare in Queensland. Uncommon in Western Australia. Common in the other states.
Plant description:
Bright green perennial herb forming dense cushions to 12 cm diameter. Leaves numerous, linear-filiform, acute, to 4.5 cm long and 0.8 mm wide, straight, spreading, soft, sparsely pilose in the basal half, innermost leaf reduced to a hyaline sheath. Flowering head broadly ovoid, to 3 mm long on a long erect stalk. Flowering between November and February. 
Fruit type:
Small brown ovoid head at end of long stalk.
Seed type:
Small orange-brown ellipsoid seed to 0.7 mm and 0.3 mm wide.
Embryo type:
Broad.
Seed collecting:
Collect fruit heads that are starting to dry off and turning pale straw colour by picking then off with your fingers.
Seed cleaning:
Place the heads 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.
Seed viability:
From one collection, the seed viability was high, at 100%.
