Oberonia setigera sp. nov. 
Planta parvula. Folia ensiformia vel subfalcata, obtusa vel 
acuta. Pedunculus elongatus. Bracteae setiformes. Sepala lat- 
eralia ovato-lanceolata. Sepalum superius lanceolatum, acumi- 
natum. Petala serrulata. Labellum 3-lobatum; lobi laterales 
majores valde dentati; lobus medius subquadratus, integer. 
Roots fibrous. Plants caulescent, 6 cm tall to tip of uppermost 
leaf. Leaves equitant, ensiform or somewhat falcate, obtuse or 
acute, 2 to 4.5 em 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 
diameter when in fruit. Floral bracts very long, setiform, 
longer than the flowers, clustered at intervals. Flowers laven- 
der, minute, clustered at intervals, but the clusters approximate. 
Lateral sepals ovate-lanceolate, about 1 mm long, 0.5 mm wide. 
Upper sepal lanceolate, acuminate, slightly exceeding 1 mm in 
width. Petals fimbriate, oblanceolate, obtuse, 1mm long. Lab- 
ellum about 1 mm long, 3-lobed, lateral lobes much larger than

The flowers of Oberonia setigera are similar to those of O. Griffithiana 
Lindl., but the middle lobe of the labellum is quite distinct and the setiform 
bracts constitute an unmistakable differentiating character.
