Taxonomy
The common snout orchid was first formally described in 1791 by Johann Gerhard König who gave it the name Epidendrum ophrydis and published the description in Observationes botanicae :sex fasciculis comprehensae. In 1997 Gunnar Seidenfaden changed the name to Dienia ophrydis. The specific epithet (ophrydis) is derived from the Ancient Greek word ophyrs meaning "brow" or "eyebrow".

Dienia ophrydis grows in wet forests, often near streams and swampy areas. It is the most widespread species in the genus and is found in China, Cambodia, Bhutan, India, Japan, Laos, Malaysia, Myanmar, Nepal, the Philippines, Sri Lanka, Singapore, Thailand, Vietnam, New Guinea and northern Queensland.
