Dicotyledons, as before, are considered under the subclasses 

 Choripetalae and Sympetalae, the sequence of the former being 

 marked by an achlamydeous or monochlamydeous floral series and 

 a heterochlamydeous floral series, while the existence of two 

 strongly marked groups in the second is indicated by their sub- 

 division into Pentacyclicae and Tetracyclicse. Dr. Warming is 

 here working on similar lines to those developed in his former 

 book, but in the nomenclature and arrangement of the orders 

 some changes are noticeable. Thus the series now begins with 

 the Verticillatae {Casuminece), followed by the Salicales and the 

 other amentiferous orders ; Proteales follows Polygonales, in which 

 PiperacecB are included; while the Hysterophyta, which in the 

 earlier work came at the end of the Choripetalous subclass, now 

 appear, as Santalales and Aristolochiales, at the end of the 

 achlamydeous and monochlamydeous series. It will be seen, 

 therefore, that there is a nearer approach to the sequence adopted 

 by Dr. Engler. To some extent the same remark applies to the 

 heterochlamydeous series, though a larger number of orders is 

 recognized than by Dr. Engler, and the Cactales are still placed 

 early in the series, next, in fact, to Centrospermae, the starting- 

 point. Engler's large order Parietales is also placed earlier in the 

 series, immediately after Sarraceniales, and is represented by two 

 orders, Parietales and Guttiferales. In the subclass Sympetalae, 

 while the treatment of the Pentacyclicae is unaltered, the families 

 of the Tetracyclicse have undergone some rearrangement. The 

 older Nuculiferae is now broken into two orders — Boraginales and 

 Verbenales {Lahiatce and VerbenacecB) , and Personatae are placed 

 between them. Oleacecs and SalvadoracecB are also separated as 

 a new order — Oleales — from the Contortae ; while, on the other 

 hand, Dij^sacecB are included in Rubiales, and Campanulinae in 

 the Synandreae, which, as before, concludes the series. The de- 

 scriptions of the orders and families follow the plan adopted 

 in the Handbook from which the excellent figures, with some 

 additions, are also taken. A B R

It is more than fifty years since the publication of Miquel's 

 Flora India Batavce, but this still remains the only account of the 

 phanerogamic flora, as a whole, of the Dutch East Indies. In 

 spite of the fact that several of the groups of flowering plants 

 have been in recent years critically worked out, there is no modern 

 general account of the flora of the island of Java. Dr. Koorders 

 seeks to supply this deficiency by the present work, which takes
