Taxonomy and naming
Caladenia lodgeana was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Margaret River and the description was published in Nuytsia.[4] The specific epithet (lodgeana) honours the Western Australian orchid enthusiast Harry Lodge.[2]
Distribution and habitat
Lodge's spider orchid is only known from the area between Margaret River and Augusta in the Warren biogeographic region where it grows in seasonal swamps.[1][2][3][5]
Conservation
Only about 137 mature plants from two populations of C. lodgeana were known in 2008. The species is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife[5] and is listed as "Critically Endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999. The main threats to the species are inappropriate fire regimes, weed invasion, four-wheel driving, grazing, trampling, picking and continued drying of wetlands due to water extraction and land clearance.[6]
