Taxonomy and naming
Caladenia interjacens was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected in the Walpole-Nornalup National Park and the description was published in Nuytsia.[4] The specific epithet (interjacens) is a Latin word meaning "intervening" or "coming between"[5] referring to the characteristics of the flowers of this species being intermediate between those of Caladenia longicauda and C. huegelii.[2]
Distribution and habitat
The Walpole spider orchid occurs between Walpole and West Cliff Point in the Jarrah Forest and Warren biogeographic regions where it grows in woodland and in low coastal heath.[1][2][3][6]
Conservation
Caladenia interjacens is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[6] meaning that is rare or near threatened.[7]
