Hab. Johore: Batu Pahat! 
Also Buitenzorg, in Java, Dr. Treub. 
Blume’s description is very short; but as far as it goes, it 
agrees with this species. The flowers are remarkably small. 
A. cordata, Hook. f., is near this, if not identical.

Hab. Selangor: limestone caves, Kwala Lumpur! 
Perak: Maxwell’s Hill! 
Flowers pale yellow, with a crimson anther. I do not 
understand how Reichenbach’s A. rhodiola, Xenia Orch., ii. 
p- 118, differs from this species. I have received plants from 
Dr. Treub, from Java, and also collected it in the above- 
mentioned localities; and in all the bracts of the inflorescence 
were of a creamy white, and not pink.

Hab. Pahang: Rocks in the stream, Tahan River ! 
This grows in clefts in the rocks in the Tahan River. It has 
a thick though short rhizome, emitting copious roots. The 
stems are very slender, and covered with grassy leaves. The 
flowers are very small. The lip is free from the column to the 
base, quite entire, with the edges at the apex thickened.
