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.

Description

Caladenia bryceana is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf Шаблон:Cvt long and Шаблон:Cvt wide. Usually, there is only a single pale green to apricot-coloured flower. The dorsal sepal is erect to slightly curved forwards Шаблон:Cvt long and Шаблон:Cvt wide, the lateral sepals broadly crescent-moon shaped, Шаблон:Cvt long and Шаблон:Cvt wide, and the petals linear, Шаблон:Cvt long and Шаблон:Cvt 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.[1]

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).[2][3] The specific epithet (bryceana) honours Frances Bryce MacIntyre.[4]

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.[7]
