Read 2nd May, 1889. 
THE Collections which have furnished materials for the following catalogue are :— 
(1) That made during the visit of the * Challenger? Expedition in April and May 1875, 
the whole of whieh has one common label as being gathered at Kobe-Kioto and on the 
Tokiado; (2) Two considerable collections made by James Bisset, Esq., F.L.S., the first 
in 1879, the second in 1887-1888, in both which the specimens have definite localities ; 
(3) А number of specimens without labels collected by Dr. Maingay ; (4) Many other 
specimens from Mr. Maries and Mr. Dickens, all of which are labelled “ Japan." 
Thunberg in his ‘ Flora Japonica,’ 1784, gives localities. for five Mosses and four 
Hepaticee. The collections made by Siebold, which have added so largely to the Flora, 
are in part described by Dozy and Molkenboer in their * Musci Frondosi inediti Archi- 
pelagi Indici, sive Descriptio её Adumbratio Muscorum Frondosorum in insulis Java, 
Borneo, Sumatra, Celebes, Amboyna, nec non in Japonia nuper detectorum minusve 
cognitorum,' 1845-1847, in which were embodied the species described in the * Annales des 
Sciences Naturelles,’ Paris, 1844 (published separately under the title * Muscorum Fron- 
dosorum Nov: Species ex Archipelago Indico et Japonia, 1844), and more completely 
recorded by Van der Sande-Lacoste in the enumeration, including the Hepatieze, which he 
contributed to Miquel’s “ Prolusio Flore Japonice,” 1867, in * Annales Musei Botanici 
Lugduni Batavorum,' vols. i. & ii. In this are contained those species collected by 
Oldham and described in the * Journal of the Linnean Society, viii. (1864), but those 
collected by the American Exploring Expedition and described by Sullivant and Les- 
quereux in the * Proceedings of the American Academy of Arts and Sciences,’ iv. p. 275, 
1857-1860, are not mentioned. Lindberg, in his * Contributio ad Floram Cryptogamam 
Авіге Boreali-Orientalis, 1872 (Acta Soc. Sci. Fenn. x. pp. 221-280), described with his 
accustomed care five Hepaticee, of which one was new, and twenty-eight Mosses, of 
whieh seven were new and additional to the Flora of Japan, from the collections of 
Maximowicz. In the ‘Mémoires de la Société de Physique et d'Histoire Naturelle de 
Genève, tom. xxvi., in his ** Choix de Mousses Exotiques nouvelles ou mal connues," 
Duby described and figured а few Japanese Mosses which he considered to be previously 
unknown, besides which a few are mentioned by Jaeger and Sauerbeck in ‘Genera et 
Species Muscorum systematice disposita, seu Adumbratio Flore Muscorum (1870-1879), 
by name only, no deseriptions of which are known. 
Amongst a number of species which are found throughout the temperate regions of 
the northern hemisphere, the Flora of J apan presents some species which are elsewhere 
round, in N. India; and a few which belong rather to the eastern side of N. America, 
without a marked affinity to the species of the Pacific coasts of that continent. "The
