Taxonomy and naming
The wispy grub orchid was first formally described in 1889 by Frederick Manson Bailey who gave it the name Oberonia pusilla and published the description in Report of the government scientific expedition to Bellenden-Ker Range: upon the flora and fauna of that part of the Colony. In 1992 Mark Clements and David Jones changed the name to Octarrhena pusilla. The specific epithet (pusilla) is a Latin word meaning "very small", "little" or "petty".
