Taxonomy and naming
Caladenia fuscolutescens was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Wellstead and the description was published in Nuytsia.[4] The specific epithet (fuscolutescens) is derived from the Latin words fuscus meaning "dark", "swarthy" or "dusky"[5]Шаблон:Rp and lutescens meaning "becoming yellow",[5]Шаблон:Rp referring to the distinctive colour of the flowers.[2]
Distribution and habitat
Ochre spider orchid occurs between Albany and Wellstead in the Esperance Plains and Jarrah Forest biogeographic regions where it grows in scrub and woodland, usually in sandy soil.[1][2][3][6]
