Commonly known as the Dwarf Spider Orchid, Caladenia bryceana subsp. bryceana is endemic to the south-west of Western Australia. It is a small orchid that has a single spreading, hairy leaf and a single green to apricot coloured flower. It is found in the far south-west corner of the state, unlike the subspecies cracens which grows near Kalbarri.
Caladenia bryceana susp. bryceana is a rare subspecies that is classified as T (Threatened flora). The orchid pictured here was photographed in the Great Southern Region of Western Australia.
Caladenia bryceana was first formally described by Richard Rogers in 1914 but in 2001 Stephen Hopper and Andrew Brown described two subspecies, including subspecies bryceana and the description of the two subspecies was published in Nuytsia. The specific epithet (bryceana) honours Bryce MacIntyre, who first collected the species in 1914.
