Distribution. 



West Sumatra, Eastcoast (Deli) Sibajak in primeval forest 1500- 1700 

 ML, frequent. LöRZINO No. 5984, 28/8-4 8. „Herb. Rhizome supraterraneous, 

 much branched. Inflorescences radical, numerous. Bracts straw-coloured 

 yellow, brownish and pale green. Branches of panicle bright red. Flower- 

 buds green, .bright red near the top. Petals pale yellow, labellum citrine, 

 lobes with bright red patches. Flowers suaveolent. Capsules bright red". 



This species though rather well agreeing with BAKER's diagnose of 

 Qeostachys clecurvata, type of the genus, cannot however be indentified 

 with that species because of the shape of the lip and the much smaller 

 dimensions of all parts. Indeed by the very broad ovate lip it obviously 

 differs from all malaccan species described by Ridley except G. penungensis. 

 Here however the leaves are very shortly petioled, the floral bracts are 

 puberulous, the calyx is 23 mm. long (fide K. SCHUMANN), the lip pu- 

 berulous, the connective not prolonged, the stylodes lanceolate. The two 

 species, however, if not synonyms are very nearly related.
