In the absence of flowers, tliis interesting plant was very nafnrally 

 placed in Luisia (from its terete leaves and long capsule) by Blume. 

 Mr. Clarke's flowering specimen enabled me to refer it to its proper 

 genus wbere it consorts with two other terete-leaved species, viz, 

 ■^. vandaruyn, Reicbb. f., of the Eastern Himalaya and the Khasia 

 Hills, and ^. cylindricum, Lindl., of the Malabar Gliats. The side 

 lobes of the lip, divided into two long subulate decurved segments, 

 and the long spur at once distinguish ^. longicornu from the others 

 The fact of the peduncle being two-flowered obliges me to discard 

 Lindley's specitic name. — J. D. H.
