Hyalosperma demissum, commonly known as moss sunray,[2] is a flowering plant in the family Asteraceae. It is a small, annual herb with whitish yellow flowers and is endemic to Australia.
Hyalosperma demissum is a rounded, small annual to 5–20 mm (0.20–0.79 in) high and sparsely covered with long, soft, straight hairs or smooth. The leaves are linear and more or less triangular in cross-section, about 5 mm (0.20 in) long, about 0.2 mm (0.0079 in) wide and gradually tapering to a point. The whitish-yellow flowers are in dense clusters amongst the foliage, the bracts are arranged in 3-4 rows, broadly oblong to oval shaped, outer bracts 2–2.5 mm (0.079–0.098 in) long, almost translucent, light green, silvery or light yellowish brown. The florets are in groupings of 15-25 and the corolla has 3 or 4 lobes. Flowering occurs from September to December and the fruit is a dry, one-seeded, compressed, egg-shaped, warty and about 0.7 mm (0.028 in) long.[2][3]
