Planta parvula. Folia ensiformia vel subfalcata, obtusa vel 
acuta. Pedunculus elongatus. Bracteae setiformes. Sepala lat- 
eralia ovato-lanceolata. Sepahim superius lanceolatum, acumi- 
natum- Petala serrulata. Labelhim 3-lobatum; lobi laterales 
majores valde dentati; lobus medius subquadratus, integer. 
Roots fibr9us. Plants caulescent, 6 cm tall to tip of uppermost 
leaf. Leaves equitant, ensiform or somewhat falcate, obtuse or 
acute, 2 to 4.5 cm long, 5 to 7 mm wide. Peduncle 12 cm 
long, thickly beset below the raceme with setiform bracts nearly 
1 cm long. Raceme densely many-flowered, about 7 mm in

The flowers of Oberonia setigera are similar to those of O. Griffithiana

bracts constitute an unmistakable differentiating character.
