Taxonomy and naming
Caladenia attingens was first formally described in 2001, Stephen Hopper and Andrew Phillip Brown. In the same paper, Hopper and Brown described two subspecies including Caladenia attingens subsp. gracillima and the description was published in Nuytsia.[6] The subspecies name ("gracillima") is the comparative form of the Latin word gracilis meaning "thin" or "slender",[7]Шаблон:Rp hence "more slender",[7]Шаблон:Rp referring to the thinner sepals of this subspecies.[2]
Distribution and habitat
The small mantis spider orchid is found between Jerramungup and Israelite Bay in the Coolgardie, Esperance Plains and Mallee biogeographic regions where it grows near creeks, granite outcrops and salt lakes.[1][2][3][8]
Conservation
Caladenia attingens subsp. gracillima is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[8]
