deseription of the species may be added: “ leaves bistratose in 
the upper half, cells not incrassate, smooth.” 
PrycnourrRtU M Favrtet, Besch.—Japan: Arima(J. H. Maiden, 
Oct. 1885, no. 71). M. Bescherelle kindly determined the plant. 
It may be observed that in the key to the Japanese species of 
Ptychomitrium which M. Bescherelle (21) gives, P. Fauriei is 
separated from P. sinense, Jaeg., by possessing leaves “ dentieulées, 
à dents courtes," P. sinense having leaves " trés entières” In 
the Arima specimens, however, as well as in other examples of 
P. Fauriei (now in the Kew Herb.) kindly sent to me by M. Bes- 
cherelle, the leaves are frequently quite entire. A safer distinction 
between these two species (whieh are often identical iu habit) is 
found in the shape and areolation of the leaf. In P. sinense the 
leaves are much broader, always triangular in outline, with 2 
broad upper part, which is not or scarcely cucullate, and the 
cells are distinctly larger, averaging 10 p; in P. Fauriei the 
leaves are long and narrow in the upper part and strongly 
cueullate, with the cella averaging 7 p. 
P. POLYPHYLLOIDES, Par.—China : glen near Ichang, c. fr. 
(Dr. A. Henry, Feb. 1888, no. 7913); Hupeh: Changyang 
(idem, Mar. 1889, no. 7482). 
C. Müller (11), in comparing the present species with P. poly- 
phyllum (Dicks.), Bry. Eur., deseribes the leaves as “ minutius 
areolata” ; but the cells are in reality slightly larger (and less 
inerassate). The basal cells of the present species differ in 
not being inerassate, and the limb of the leaf is wider and 
irregularly bistratose. In the original diagnosis the capsules are 
described as * brevissime pedicellata ”, but in some specimens 
determined by Müller in the Kew Herbarium (Bryoth. E. Levier, 
no. 1525 b) the seta is often 5-7 mill. long, and in Dr. Henry’s 
speeimens it reaches to over 10 mill. 
HzpwIGIA CILIATA, Ehrh., var. VIRIDIS, Bry. Eur.—China: 
on rocks at Pih-quan, c. fr. (Dr. W. T. Alexander, Feb. 1846, 
no. 3); rocks in the mountains, Chusan (idem, Jan. 1816, no. 4); 
city-wall, Ningpo (Oldham, 1861) Japan: c. fr. (Textor) 
(Diekins, no. 77) (Moseley, * Challenger ' Expedition, 1875) ; 
rocks, Nagasaki (Oldham, no. 513). 
This variety appears to be not uneommon in China and Japan, 
although it does not seem to have been hitherto recorded from 
Asia.
