Taxonomy and naming
This orchid was first formally described by William Nicholls in 1948 from a specimen he collected near Kojonup. Nicholls gave it the name Caladenia dilatata var. falcata and published the description in The Victorian Naturalist.[4] In 1989, Mark Clements and Andrew Brown raised it to species status.[5][6] The specific epithet (falcata) is a Latin word meaning "sickle-shaped" or "hooked"[7] referring to the upswept lateral sepals.[2]
Distribution and habitat
Fringed mantis orchid is found between Wongan Hills and Jerramungup in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee biogeographic regions where it grows in woodland, shrubland or near granite outcrops.[1][2][8]
Conservation
Caladenia falcata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[8]
