BOTANICAL KETKOSPECT. 105 



(Siebold), Biota (Kndl.) and ChanMecyparis (Spach.) are merged into 

 Tliuia (Thuya), but the last-named is now reunited to Cupressus. A 

 few other changes made by Bentham, such as the merging of Pseudo- 

 larix (Gord.) into Larix, and the grouping of Cephalotaxus with the 

 Sequoias of California and the other Taxodineae are not in harmony 

 with ascertained facts or with more recently acquired information. 

 Mr. IJentham was succeeded by Professor Eichler of Berlin, whose 

 elaboration of the Coniferae was published two years after his death in 

 Engler and Prantl's Naturliclien Pflanzenfamilien, 1887. In this classifi- 

 cation the genera are arranged in two primary divisions, Pinoideae and 

 Taxoidese, the former including the Conifers proper and the latter the 

 Taxads, thus emphasising the distinction made by Parlatore, but still 

 retaining them in one Natural Oder. The Pinoidese are divided into 

 Abietineae and Cupressineee with several tertiary divisions, and the 

 Taxoideae into Podocarpeae and Taxeae ; the genera are much the same 

 as in Bentham and Hooker's Genera Plantaruni, but Chamaecyparis, 

 Thujopsis and Pseudolarix are retained and Pseudotsuga is merged into 

 Tsuga. 



In 1892 a "Conifer Conference" was held by the Royal Horti- 

 cultural Society in their garden at Chiswick, on which occasion was 

 brought together from all parts of Great Britain the most remarkable 

 collection of specimens cut from Taxaceous and Coniferous trees and 

 shrubs ever witnessed. The information gained therefrom, and especially 

 from the papers read and which form the fourteenth volume of the 

 Journal of the Society, prepared the way for a further systematic 

 revision of the Order, which was undertaken by Dr. Maxwell T. 

 Masters, and the result published in 1893 in the thirtieth volume 

 of the Journal of the Linnean Society. The systematic arrangement 

 there elaborated is, with few deviations, adopted in the following 'pages.
