474 DE. MAXWELL T. MASTERS ON 



types brought home by the late Mr. John Gould Veitch), as well 

 as living specimens in their nurseries and in various other horti- 

 cultural establishments. The library at Kew has also been of 

 great service to me in referring to the numerous publications 

 relating to the subject in hand. 



In drawing up the list, I have followed the arrangement of 

 the genera adopted by Mr. Bentham in Benth. et Hook. ' Genera 

 Plantarum,' vol. iii. p. 420 (1S80). As to the species, I have 

 followed the publications of Murray, Parlatore, Eugelmann, and 

 other authors ; but I have personally examined all those native to 

 Japan, except in the case of some genera (as Juniperus and Podo- 

 carpus), wherein, from lack of material, I have been constrained to 

 depend chiefly on the labours of others. 



The tabular list at pp. 483-485 comprises, in the first column, an 

 enumeration of all the species known to inhabit the Japanese islands, 

 inclusive of Yesso. The succeeding columns are intended to show 

 the distribution of the Japanese Conifers in adjacent countries, as 

 well as to indicate the existence and geographical distribution of 

 nearly allied or " representative species." The columns relating 

 to the mainland of North-east Asia and to the islands of Sachalin 

 and Yesso contain, it is believed, a complete enumeration of the 

 species so far as they are known. In the remaining columns 

 only such species are entered as may be considered representa- 

 tive, very nearly related, or analogous to the Japanese species, or 

 which have some special interest to warrant their introduction. 

 Separate hsts are given for the Kurile Islands and for those 

 of Sachalin and Yesso, for the purpose of showing the relation of 

 the Coniierous flora of Japan proper to that of North-east Asia 

 and that of North-west America, between which countries and 

 Japan these islands are situated. These lists must, of course, be 

 looked on as approximately correct only; for, doubtless, much 

 yet remains to be learnt of the floras of these regions 



The authorities specially referred to for indications as to the geo- 

 graphical distribution of particular species have been :-Parlatore 

 m DeCandolle's 'Prodromus,' xvi. sect. 2, 1868; DeCandolle's 

 Geogranhie Botanique ;' Tchihatchef's French translation of 

 Gr.sebach s ' Vegetation der Erde,' enriched as it is by notes of 

 the translator and of M. Fournier ; Beinling's memoir ' Ueber die 

 Geographische Verbreitung der Coniferen;' Hildebrand's paper 

 entitled » Die \erbreitung der Coniferen in der Jetztzeit und in 

 den fruhercn geologischen Perioden," and other general works.
