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. Glabra from Latin meaning smooth, without hairs.

Found on the lower Eyre Peninsula, Yorke Peninsula, Kangaroo Island, southern Mount Lofty Ranges and the lower South-east, growing mud around temporary freshwater pools and stream margins. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Rare in Tasmania. Common in the other states.
Plant description:
Annual or ephemeral herb to 8 cm high, forming small scattered tufts, dull-green or becoming reddish. Leaves few, linear to filiform, acute, to 8 cm long and 1 mm wide, lax, flattened, glabrous, innermost leaf reduced to an obtuse hyaline sheath. Flower head cylindrical, to 3 mm long and 0.7 mm wide on a long erect stalk. Flowering between October and November.
Fruit type:
Small red-brown cylindrical  head at end of long stalk.
Seed type:
Small orange-brown ovoid seed to 0.4 mm and 0.2 mm wide.
Embryo type:
Broad.
Seed collecting:
Collect whole plant that are starting to dry off and turning pale straw colour.
Seed cleaning:
Place the plant material in a tray for 1-2 week to dry. Then rub the pods 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%.
