144 SUPPLEMENT TO THE FLORA HONGKONGENSIS. 
Mettenius consider it to form, with Zsoétes, the type of a distinct 
naturalorder; whilst Milde regards each of the three genera as 
constituting a distinct suborder of Lycopodiacez. 
The Moss-flora of Hongkong does not appear to be at all rich. 
Mr. J. C. Bowring is, I believe, almost the only person who has 
paid any attention to the collection of these plants. The follow- 
ing brief and, no doubt, very imperfect list is compiled from a 
notice of Chinese Mosses published by Mr. Wilson in the seventh 
volume of Hooker’s * London Journal of Botany? (1848), and 
from Mr. Mitten’s various important contributions to Bryology 
inserted in the ‘ Proceedings of the Linnean Society.’ Messrs. 
Sullivant and Lesquereux’s enumeration of the Mosses collected 
during the United States’ North Pacifie Exploring Expedition, 
published in the ‘ Proceedings of the American Academy,’ pro- 
bably includes a number of Hongkong species; but I have un- 
fortunately been unable to get access to this. A list of Ja- 
panese Mosses, by M. Van der Sande-Lacoste, will be found in 
the second volume of the late Professor Miquel's * Annales Musei 
Botanici Lugduno-Batavi ;' and a proportion of these will doubt- 
less occur in Hongkong.
