Taxonomy and naming. "Caladenia granitora" was first described  in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Mount Manypeaks and the description was published in "Nuytsia". The specific epithet ("granitora") is derived from the Latin words "graniticus" meaning "of granite" and "ora" meaning "the coast", referring to the habitat preference of this species. Distribution and habitat. The granite spider orchid occurs between Mount Manypeaks and Cheyne Beach in the Waychinicup National Park where it grows in heath on coastal granite ourcrops. Conservation. Surveys of "Caladenia granitora" recorded a total of 63 individuals in four populations. In 2014, the species was classified as "Threatened  Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife. The main threats to the species are recreational activities, road maintenance, altered fire regimes and small population size.
