Caladenia bryceana is a species of flowering plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It is a dwarf spider orchid with a single spreading, hairy leaf and a single green to apricot-coloured flower. There are two subspecies differing in the features of the labellum.
Caladenia bryceana is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf 40–80 mm (1.6–3.1 in) long and 5–12 mm (0.20–0.47 in) wide. Usually, there is only a single pale green to apricot-coloured flower. The dorsal sepal is erect to slightly curved forwards 8–22 mm (0.31–0.87 in) long and 1.5–2.0 mm (0.059–0.079 in) wide, the lateral sepals broadly crescent-moon shaped, 7–10 mm (0.28–0.39 in) long and 2–3 mm (0.079–0.118 in) wide, and the petals linear, 9–11 mm (0.35–0.43 in) long and 1.0–1.5 mm (0.039–0.059 in) long. The labellum is two-tone green and ends in a dark maroon tip, with a dense band of tall calli along the centre of the labellum but ending short of the maroon tip. Flowering occurs from August to October.[2]
