ORCHIDACEtE 



here specimens that are cultivated in Manila under the name 

 Vanda luzonica. The material I have examined appears to be 

 a variety of V. tricolor, but as it is quite probable that there are 

 differences between V. tricolor and V. luzonica that are conspic- 

 uous in living plants, the name V. luzonica may represent a dis- 

 tinct species. The flowers are said to be nearly odorless, white, 

 with the labellum white at base and light purple above. 



My specimens are from Mount Balacbac, Bulacan Province, Luzon, 



Loher 6006. 



88. ANGILECUM Bonj 



A single species is known to be a native of the Philippines, 



1. Angraecum philippinensis Ames in Phil. Journ. Sci. 2 : 336 ; 

 4 : 597. 



Luzon, Mindoro. 



89. SACCOLABIUM Bl 



As at present understood, Saccolabium is a small genus partly 

 distinguished from Sarcochilus by the absence of a foot on the 

 column. It is represented in Java, Celebes, New Guinea, etc. 

 Under Saccolabium numerous species have been reported from 

 the Philippines. Saccolabium bijidum Lindl. = Sarcanthus bifidus 

 Ames. S. Blumei Lindl. = Rhynchostylis retusa Bl. S. chionan- 

 thum Lindl. = Schwnorchis micrantha Bl. S. compressum Lindl. = 

 Robiquetia compressa Schltr. S. miniatum Lindl. = Ascocentrum 

 miniatum Schltr. 



The synonymy of Rhynchostylis retusa in Orchidace^e, vol- 

 ume 2, should be studied in this connection. Several species have 

 been referred to the Philippines under Saccolabium which are 

 unknown to me, or are not represented in the Bureau of Science 

 collection. These I have purposely omitted from my list, as they 

 are doubtful.
