PREFACE. 



The papers contained in this volume originally appeared in the 

 Journal of the Asiatic Society of Bengal. For the convenience of 

 botanists interested in the Flora of the region of which they treat, I 

 had some spare copies of each printed off as it appeared, and these are 

 now issued as a volume. The volume containing my description of the 

 Thalamifloral orders was issued some years ago. The present volume 

 covers the Disciflorce (in the sense of the Genera Plantarum of Messrs. 

 Bentham and Hooker) ; and, in the course of a year or so, I hope to issue 

 a similar account of the Calyciflorce. It will be observed that each page 

 bears two numbers. The one at the top of the page is that of the volume 

 of \h& Journal in which the paper originally appeared, but it is not referred 

 to in the index ; it may be used, however, by anyone quoting these papers. 

 The numbers at the bottom of the pages, which run continuously, are 

 those used in the index. The dates of the original publication of the 

 three papers contained in the present volume are as follows : — 



No. 6. Orders XX. to XXVI., . . . August, 1893. 

 „ 7. „ XXVII. to XXX., . . April, 1895. 



„ 8. „ XXXI. to XXXVI., . . July, 1896. 



It may be useful here to mention that in the following pages the 

 length given for a leaf is that of the blade only, the measurement of the 

 petiole (if any) being given separately; and that the breadth given for 

 a leaf is that of its broadest part.
