148 MR. W. MITTEN ON MUSCI AND HEPATIC 
both contain many perfect seeds; but the solitary or abnormal 
form seems to be commonly rather larger. 
The Hookerian Herbarium contains specimens of the plant 
from various parts of tropical Africa, and all present the double 
type of flowering, which is not so obvious in those of India and 
Australia. 
On some Species of Musci and Hepatice, additional to the 
Florag: of Japan and the coast of China. By WILLIAM 
Mirren, A.L.S. 
[Read April 21, 1864. ] 
Tue first list of the species of Musci from Japan and the adjacent 
islands was published in 1859, in the ‘ Proceedings of the Ame- 
rican Academy,’ by Messrs. Sullivant and Lesquereux, from 
the collections made during the American Exploring Expedi- 
tion under the command of Captain Rodgers; seventy-eight 
species in all were enumerated, of which twenty-four were con- 
sidered new, and the remainder referred to known European 
and North American forms. In the collection made in 1861 by 
Mr. Oldham, and now in the Herbarium of Sir W. J. Hooker, 
the proportion of European forms is much less, and is represented 
rather by cosmopolitan species than by any referable to particular 
areas, and it would appear that the Musci of Japan consist of a 
mixture of the forms of northern temperate regions with others 
principally tropical, and these corresponding very nearly with 
those of the Indian Archipelago, whence it is probable that & 
very large number of species will be found to inhabit the islands 
included in Japan.
