ORCHIDACEM 17 



STUDIES IN THE ORCHID FLORA OF THE 



PHILIPPINES 



The greater part of the species listed in the following paper 

 were collected for the Bureau of Science of Manila. The mate- 

 rial from which the descriptions were drawn has been in most 

 cases carefully worked over in the herbaria of the Royal Gar- 

 dens at Kew and of the British Museum of Natural History, or 

 compared with the types of Blume's Javan orchids preserved at 

 Leiden. 



The specimens distributed by H. Cuming, with which I have 

 made comparisons, are indicated by the numbers published in 

 Vidal's Phanerogamse Cumingianse Philippinarum. My know- 

 ledge of Cuming's plants is derived from the specimens deposited 

 in the herbaria of Kew and of the British Museum. I have also 

 made note of the orchids deposited in the Gray Herbarium at 

 Cambridge, collected in the Philippine Islands by the Wilkes 

 Expedition, which Reichenbach described and published in Otia 

 botanica Hamburgensis. Through the kindness of Dr. N. L. Brit- 

 ton, it has been possible to include the orchids preserved at the 

 New York Botanical Garden which R. S. Williams collected during 

 his botanical explorations of the Philippines. In addition to the 

 above-mentioned sources I have drawn on my own herbarium for 

 species which might lend value to the paper. 



The figures of flowers and analytical drawings were, without 

 exception, constructed with the aid of the camera-lucida. These 

 have been prepared from dried material, and therefore, while accu- 

 rate in outline, they do not always exhibit the attitudes of the parts 

 characteristic of the living flower. Each species described as new 

 is figured, in order that with greater surety it may be referred to 

 its proper place in synonymy should errors have been committed 

 through inadequacy of material or oversight. No attempt is made
