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.[4] 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.[2][5]
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 outcrops.[1][2][3][6][7]
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.[6] The main threats to the species are recreational activities, road maintenance, altered fire regimes and small population size.[7]
