Taxonomy and naming
Caladenia heberleana was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected in the Hassell National Park, and the description was published in Nuytsia.[4] The specific epithet (heberleana) honours Ron Heberle, an orchid enthusiast.[2]
Distribution and habitat
Heberle's spider orchid occurs between Augusta and Cape Arid in the Esperance Plains, Jarrah Forest and Mallee biogeographic regions, where it usually grows in deep sandy soil in woodland. Its flowering is stimulated by summer fires but flowering plants are also found around areas that are swampy in winter, even in the absence of earlier fires.[1][2][3][5][6]
Conservation
Caladenia heberleana is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[5]
