Taxonomy and naming
Caladenia graminifolia was first formally described by Alex George in 1971 and the description was published in Nuytsia from a specimen at Culham Inlet.[4] The specific epithet (graminifolia) is derived from the Latin gramen, graminis meaning "grass" and -folius meaning "-leaved", referring to the grass-like leaf of this orchid.[5]
Distribution and habitat
The grass-leafed spider orchid occurs between Mount Manypeaks and Israelite Bay in the Esperance Plains and Mallee biogeographic regions. It grows in woodland under tall shrubs and sometimes on granite outcrops.[2][3][6]
Conservation
Caladenia graminifolia is classified as "Not Threatened" by the Western Australian Government Department of Parks and Wildlife.[6]
