SECTION Eublepharon J J Verm., Schuit. & de Vogel 2014

TYPE = !Bulbophyllum eublepharon Lindley 1861


This sections orchids are epiphytes with creeping rhizomes giving rise to distinct, longitudinally wrinkled with age pseudodulbs carrying a single, persistent leaf that blooms on an elongate to subumbellate, racemose, 2 to many flowered inflorescence carrying resupinate flowers with the basal node of the pedicel level to slightly above the attachment of the floral bract. The usually 3 nerved dorsal sepal is free, and has entire to denticulate margins, the laterals are 1 to 2 times longer than the dorsal, are usually free and are 3 to 5 veined. The petals are 1 to 3 veined and have erose to fimbriate margins. The undivided lip is on a thin ligament. The column has the stigma proximally not protruding and the column foot has teeth near the apex. The stelida are 1 to 2 times the length of the column or shorter, with or without teeth on the upper or lower margins. The anther surface is not concave and the anterior margin is drawn out or not. There are 4 pollina.

Several species of section Eublepharon have ciliate petals, a character shared with SECTION Hirtula Ridley 1908. The two differ by the pseudobulbs that wrinkle with age along longitudinal lines in section Eublepharon rather than in random patterns as in section Hirtula. Additionally, section Eublepharon never has auricles at the base of the lip, flanking the ligament. Species of section Eublepharon with a congested or subumbellate raceme resemble SECTION Ephippium Schlechter 1913 and SECTION Cirrhopetalum [Lindl.] Rchb.f 1861, but differ by having the lateral sepals not curved inwards proximally

There are about 10 species occuring in montane forests at elevations up to 3300 meters in Sri Lanka, India, Nepal, Bhutan, China, Taiwan, Japan, Laos and Vietnam
