Taxonomy and naming
Caladenia armata was first formally described in 2006 by David L. Jones who gave it the name Arachnorchis armata and published the description in Australian Orchid Research from a specimen collected on the Majura Field Firing Range.[2] In 2010, Gary Backhouse changed the name to Caladenia armata.[3] The specific epithet (armata) is a Latin word meaning "furnish[ed] with weapons",[4] referring to the type location.[1]
Distribution and habitat
This spider orchid is only known from ten individual plants growing in the Majura Field Firing Range in open forest of red stringbark (Eucalyptus macrorhyncha) and white gum (Eucalyptus rossii.[1]
