Plant description

Tiny herb forming dense, compact rounded tufts to 25 mm diameter. Leaves to 9 mm long, strongly recurved, innermost one reduced to an obtuse hyaline sheath. Inflorescence subsessile or borne on an axis up to 3 mm long, hence flowers not extended beyond leaves. Lower bract with a broad, pale, papery basal sheath to 3 mm long, abruptly narrowed into a terete recurved lamina. Upper bract to 3 mm long, sheathing at base, broad, pale and papery. Inflorescence units 3 (or rarely 2) per head-like cluster. This subspecies is distinguish from the other species C. cephaloformis ssp. murrayi which have only 1 (very rarely 2) inflorescence units per head-like cluster. Flowering between September and November. Fruit tiny brown head. Seed embryo type is broad.

Seed collection and propagation

Collect seeds between November and December. Collect whole plant that are starting to dry off and turning pale straw colour by picking then off with your fingers. 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.
