NEW OR RARE MALAYAN PLANTS. 41 



foliage and perianth it is absolutely identical with 

 Reihenbach's figure except that it has a short distinct 

 conical spur to the lip, pendant, about half the length 

 of the petal. The column however differs. From the 

 side of the anther projects a triangular flap, about half 

 its length at the base, behind this is a papillose stigma. 

 The rostellar lobes are broad inflexed fleshy truncate as 

 long as the anther processes. The pollinia are more 

 pyriform with long narrow pedicels widest at the apex 

 and narrowing to a terete-portion ending in a small 

 rounded disc. The flowers are white. The plant was 

 obtained from Tonkin. 



The species seems to be a good and distinct one, and 

 I see nothing to suggest it is a monstrosity. The spur 

 varies very much in length in the various flowers, and in 

 some I cannot see any. In others very short not a 

 quarter of the length of the petal. The minute ciliation 

 of the lip and petals by Reichenbach is really a very 

 minute denticulation. 



H. geniculata, Don. this fine white Habenaria was 

 also brought by Mr. Micholitz from the same locality. 



Habenaria borneensis, n. sp.
