This, the latest of the divisional floras of Australia, besides 

 listing the plants collected during recent explorations, notably 

 the Barclay expedition, in the Northern Territory — viz., that 

 portion of Australia north of the 26th parallel of south latitude 

 and between the boundaries of Western Australia on the west 

 and Queensland on the east, records all the plants previously 

 noted in the National Herbarium (Melbourne) Census and other 

 publications as occurring in " Northern Australia " — " Northern 

 Australia " probably including, as well as the Northern Territory, 

 portions of northern Western Australia and northern Queens- 

 land. The flora is arranged in orders in the sequence of 

 Engler's System, and extends to 281 pages [y\ x 4I inches 

 printed). Most of the recent collections, which include some 

 new species and genera, were made by Mr. G. F. Hill, who was 

 the botanist and entomologist of the Barclay expedition. A 

 rather novel feature is a " Key to the Australian Natural Orders," 

 in which the characters of each order are set out in tabular 

 form ; this extends to 14 pages {i^l x 7^ ), and can hv made use 

 of by workers in any State. Two pages of popular names are 

 given and a large number of plants are grouped under different 

 headings, indicating their economic or other qualities. In tlie 

 appendices by Mr. J. H. Maiden on the eucalypts and acacias 

 will be found a great deal of valua]:)le information applicable 

 to other portions of Australia. A new eucalypt is named after 

 Professor Baldwin Spencer, K.C.M.G., and a variety of Acacia 

 sericata is named Ditnnii after Mr. E. J. Dunn, I-'.G.S., late 

 (iovernment (ieologist of Victoria. The volume is well indexed, 

 and includes twenty-seven plates, drawn by the Misses E. 

 M'Lennan, B.Sc, I. Cookson, B.Sc, E. Archer, B.Sc, and M. 

 Flockton (Sydney) : als(j a map of the Northern Territory, by 

 Capt. A. L. Rossiter, showing the route of the Barclay Expedi- 

 tion and the characteristic vegetation at the various camping 

 places.
