PREFACE 



general type as that of the Malay Peninsula, Java, Sumatra, 

 Celebes and the Philippines. The species that are known to have 

 an extra-limital range are for the most part Malayan. Spiranthes 

 sinensis (Pers.) Ames is one of the few exceptions to this rule. 

 Below, under Dendrochilum, I have discussed the relationship 

 between the species of Mount Kinabalu and Luzon. What is true 

 of Dendrochilum in the regions mentioned seems to be equally 

 true of all the large genera common to Borneo and neighboring 

 regions. 



In addition to the orchids found by Chaplain Clemens in 1915 

 I have added in the following enumeration a small collection 

 made on Kinabalu in 1916 by George Haslam and a complete 

 list of all the species reported to be natives of the mountain. 



With regard to several of the orchids described in the text 

 perplexities have arisen, but the more troublesome of these were 

 promptly removed through the kindness of Sir David Prain, 

 Director of the Royal Gardens, Kew, who sent sketches of types 

 preserved in the Kew Herbarium. I am also indebted to Mr. 

 Burkhill, Director of Gardens, Straits Settlements, who secured 

 for me a photograph of the type of Dendrochilum conopseum 

 Ridl. which is preserved in the Sarawak Museum. 



It is a pleasure to acknowledge the valued cooperation of my 

 assistant, Mr. Charles Schweinfurth, in the examination and de- 

 scription of the material which has passed through my hands 

 in the preparation of this work. The species that represent joint 

 authorship are designated by the letters A. & S. 



The following enumeration includes fifty-two genera and two 

 hundred and twenty -two species. It is highly probable that inten- 

 sive explorations throughout the year will bring to light many 

 additions and confirm my belief that Mount Kinabalu will prove
