in lobos binos divaricatos subovatos divisum. Totum labellum 

 circiter 2.5 cm. longum, lobi ± 7 mm. longi, circiter 6 mm. lati, 

 leviter crenulati. Dentes labelli circiter 1 mm. longi. Saccus 

 sepalis lateralibus occultus. Gynostemium 8 mm. longum, sub 

 stigmate lamellis binis in saccum labelli dependentibus. 



Cystopus philippinensis is closely related to C. occultus Bl. 



Luzon, Province of Tayabas, Infanta, C. B. Robinson Bur. Sci. 9446, 

 August 28, 1909. Altitude 1000 meters above sea level. 



26. ANCECTOCHILUS Bl 



Wenzel 0286 from Leyte is the only material referable to this 

 genus that I have seen among the Philippine orchids I have ex- 

 amined. It is a low plant with three capsules and the withered 

 remains of the flowers. From dried specimens the leaves appear 

 to have been reddish beneath, very dark green above veined with 

 red. From the withered remains of the flowers the generic char- 

 acteristics of Ancectochilus are discoverable. The closest affinities 

 appear to be A. sctaceus Bl. and A. Roxburghii Lindl. 



27. MACODES Lindl 



A genus of about eight species with one representative in the 

 Philippine Islands. 



1. Macodes Petola Lindl Gen. & Sp. Orch. 497; Reichb. f. 

 Xenia Orch. 1 : 227, t. 96, figs. 1-5 ; Blume Fl. Jav. Orch. 100, t. 31, 

 fig. 2, t. 36 (D). 



Several species of Macodes have been reported from the Phil- 

 ippines, but 31. Petola is the only one that I have seen. M. Pe- 

 tola is an addition to my previously published lists. 



Luzon, Province of Tayabas, Mount Binnang, C. B. Robinson Bur. Sci. 

 94-64-, August 29, 1909. Altitude 300 meters. Flower brown-purple, yellow- 

 tipped; Laguna Province, Mount Maquiling, M. Ramos Bur. Sci. 13705, 

 September 13, 1911.
