Description
Centrolepis pedderensis is a summer-growing perennial herb (or a facultative annual in less favourable sites), forming loose tufts up to 7 cm in diameter. Individual tufts are composed of densely packed very narrow leaves to 3 cm long, and are overtopped by solitary flower heads. Leaves are numerous, distichous, suberect in a fan-shaped cluster and glabrous. The leaf sheath is 3 to 10 mm long, passing abruptly into a subterete keeled lamina 3 to 20 mm long. The scapes are slightly longer than the leaves and are often crimson and are glabrous. The reproductive parts are enclosed within two overlapping bracts that are erect and lanceolate to 4.5 to 5 mm long, their outer surfaces light brown, and often flushed crimson. They consist of 2 to 6 parts comprised of reduced flowers (pseudanthia). 1 to 2 of the pseudanthia are bisexual and the others lack the stamen. The stamen’s filament and anther are crimson. The stigma carries stout 3-lobed receptive hairs (Curtis 1984, Cooke 1992, Curtis & Morris 1994).
