Plant and Inflorescence Photos by Kurt Keller

Deep shade Warm Cool Summer

Common Name The Thai Eria

Flower Size .2" [4mm]

Found in Myanmar?, Thailand and Vietnam at elevations of 500 to 2000 meters as small sized, warm to cool growing epiphyte with cylindrical, to fusiform stems carrying 2, apical, elliptic, acute leaves that blooms in the summer a 6" [15 cm] long, white wooly, many flowered inflorescence with triangular, acuminate-acute floral bracts

Said to be a synonym of E stricta but this one seems quite different. The petals are half as broad as E stricta, the midlobe is as long as broad at the base or slightly longer and is very recurved. The inflorescence of E siamensis is white wooly while E stricta is sparsely hairy and the floral bracts are larger, triangular and acute-acuminate.
