Taxonomy and naming
This orchid was first described in 1930 by Edith Coleman who gave it the name Caladenia dilatata var. rhomboidiformis and published the description in The Victorian Naturalist.[4][5] In 1971, Alex George recognised it as Caladenia longiclavata var. rhomboidiformis[6] and in 1989 Mark Clements and Stephen Hopper raised it to species status.[7] The specific epithet (rhomboidiformis) is derived from the Ancient Greek word ῥόμβος rhombos meaning "rhombus",[8]Шаблон:Rp the suffix oid meaning "likeness"[8]Шаблон:Rp and the Latin word forma meaning "shape" or "figure"[8]Шаблон:Rp referring to the diamond-shaped labellum of this orchid.[2]
Distribution and habitat
The diamond spider orchid is found between Busselton and Augusta in the Jarrah Forest and Warren biogeographic regions where it grows in a variety of habitats but often in jarrah forest, or Banksia or sheoak woodland.[1][2][3][9]
Conservation
Caladenia rhomboidiformis is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[9]
