Bletiinae
Bletiinae is a small-sized subtribe of orchids in the Arethuseae tribe of the subfamily Epidendroideae.
The tribe was initially categorized by John Lindley in 1840. Bletiinae has been recognized as a sub-tribe to Arethuseae. However, most of its genera were removed in 2005, and the subtribe moved to Epidendreae.
