Description

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]

Taxonomy and naming

Caladenia bryceana was first formally described by Richard Rogers in 1914 from a specimen collected near Gnowangerup. The description was published in Transactions and Proceedings of the Royal Society of South Australia) . [3] [4] The specific epithet (bryceana) honours Frances Bryce MacIntyre. [5]

In 2001, Noel Hoffman and Andrew Brown described two subspecies of C. bryceana in the journal Nuytsia , and the names are accepted by the Australian Plant Census:

Distribution and habitat

This spider orchid grows along watercourses and in winter-west place in two widely disjunct populations in the Esperance Plains, Geraldton Sandplains, Jarrah Forest and Mallee bioregions of south-western Western Australia. [8]
