8 ORCHIDACEM 



Luzon, Philippine Islands, by Mr. Thomas E. Borden (no. 799), 

 and subsequently near the same locality on August 8, 1904, by 

 Mr. Elmer D. Merrill (no. 3856), and again the following day 

 by Mr. T. E. Borden (no. 1597). It is an interesting addition to 

 Ridley's section Distichce of Liparis, recently transferred to Ces- 

 tichis. Thou., by Dr. E. Pfitzer. It is a much more robust plant 

 than Cestichis disticha, Pfitz., from which species it is easily dis- 

 tinguished by its juxtaposed pseudobulbs. From Cestichis com- 

 pressa (Lindl.), C. Cumingii (Ridley), and C. divergens (J. J. 

 ' Smith), aU closely allied species, it is at once separated by its lan- 

 ceolate lip.
