Flowers large, " dull orange, and slightly veined with dull-red." 

 Petals linear spathulate, very narrow. Labellum represented as al- 

 most 4-lobed, or 3-lobed, with the central lobe emarginate. 



The quotation from the Hb. Amb. in the Flora Indica is 

 wrong. Roxburgh probably meant Herba supplex, t. 51.

The species appears to have been passed over entirely.

 foliis scalpelliformibus subacutis, floribus racemosis, labello

Hab. — Amboyna, Roxburgh.; Assam, Major Jenkins. 



Habit much like that of A. Roxburghii. The flowers are however 

 very much smaller, and yellow. Petals narrow lanceolate. 



The Assam specimens vary a good deal, generally the stems 

 are simple, the flowers whitish, and the labellum almost bilo- 

 bed. Sometimes however the stem is branched : the leaves 

 brOader, and so compressed as to be almost flat, and the lip 

 faintly spotted with red. In one instance the flower was 

 solitary and terminal.
