species ; the majority of the specimens described were 

 collected by myself daring the expedition, but a few of them 

 are allied species, previously represented in the Kew 

 Herbarium, and in these cases the collector's name is given. 

 Descriptions of two new American Bignoniacea; are appended. 

 The enumeration of species collected, with their geographical 

 distribution, etc., and a discussion of the general results 

 attained, is reserved for a subsequent paper. 



I desire to record here my indebtedness to the Eoyal 

 Society for a grant of £50 towards my expenses on the 

 expedition, and to Professor Chodat for the description of 

 Securiclaca cvmazonica: my thanks are also due to Mr. Hemsley 

 and all my colleagues, and more especially to Dr. Stapf, for 

 much kindly assistance and advice on critical points.
