Arethuseae
Arethuseae is a mid-sized tribe of orchids in the subfamily Epidendroideae. This tribe was initially categorized by John Lindley in 1840. Its largest subtribes are Arethusinae and Coelogyninae.
Bletiinae was once considered a sub-tribe of Arethuseae, but it was moved to Epidendreae in 2005.
