PREFACE 



whose honor Linnaeus named the genus Camellia, was a mission- 

 ary who passed a number of years in the Philippines, where he 

 devoted part of his leisure to the collection and study of botan- 

 ical specimens. In 1704, in an appendix to the third volume of 

 Ray's Historia Plantarum, descriptions of Camelli's plants were 

 published. This appendix is of importance, as it constitutes one 

 of the earliest records of Philippine botany. Camelli prepared 

 drawings to illustrate his specimens, but no attempt was made 

 to reproduce them until Jacob Petiver published a plate of the 

 orchids in his Gazophylacium. Petiver's plate represents modi- 

 fications of the originals, much reduced, that make possible ap- 

 proximate identifications. The original drawings are still extant, 

 and are preserved in the Sloane collections at the British Mu- 

 seum.* 



In the citations of collectors' numbers the abbreviations Bur. 

 Sci. and For. Bur. refer to the Bureau of Science and the For- 

 estry Bureau at Manila. C. A. Wenzel's field numbers, cited in 

 the references to distribution, are preceded by a cipher, to dis- 

 tinguish his orchids collected especially for me from the speci- 

 mens of his general collections distributed to the subscribers to 

 his sets of plants from Leyte. As Wenzel unfortunately num- 

 bered both his orchids and general collections alike, confu- 

 sion would be inevitable were not some means of distinction 

 adopted. 



A complete bibliography has not been included in this work, 

 as most of the species have been amply treated in the preced- 

 ing volumes of Orchidace^e or in my contributions published 

 in the Philippine Journal of Science. Furthermore, with very few 



* Photographic copies of the orchid drawings, for which I am indebted to Dr. A. B. Rendle, 

 are in my herbarium.
