MOSSES FROM CHINA AND JAPAN. 455 
TRICHOSTOMUM ORIENTALE, O. Müll. (Tortula indica, Hook.). 
— China : Hongkong, c. fr. (C. Ford, Aug. & Nov. 1889, nos. 
207, 209).—These Chinese specimens frequently bear. stalked 
multicellular gemma, borne in dense clusters on the stem in 
the axils of the leaves, and I have found the same to occur 
in Ceylon examples of the species (Herb. Ind. Or. Hook. fil. & 
Thomson, no. 162). The moss described by Bescherelle (19. 
p. 81) as a new species, under the name of Barbula scleromitra, 
from Tonkin, appears from the deseription to be very close 
to the present species. Bescherelle says of his species: * Cette 
mousse diffère du Tortula indica, Hook. .... par l'inflorescence 
et la verrucosité des coiffes et des feuilles... . . La coiffe est 
scabre dés la base, un peu plus fortement tuberculeuse vers 
le sommet." The calyptra of Trichostomum orientale was de- 
scribed and figured as smooth by Sehwaegriehen (Hedw. Sp. 
Muse. Frond., Supp. i. sect. 1, p. 143, tab. xxxvi.); subsequent 
authors, as far as I can find, have not mentioned the point, 
although both Hooker (Muse. Exot. ii. tab. 135. fig. 5) and 
Dozy and Molkenboer (Bryol. Jav. tab. 81. fig. 19) figure the 
calyptra as smooth. In all the specimens of T. orientale (with 
young fruit) in the Kew Herbarium, however, the calyptra is 
rough in the manner described above for * B. scleromitra.” 
The upper leaf-cells are minutely papillose on both sides, and 
the nerve is very rough at back. There is a moss in the Kew 
Herbarium from Tai-wan, Formosa (G. W. Playfair, Jan. 1889), 
determined by Brotherus as 7. orientale. This is barren and 
young, but agrees well with the species. T. orientale has not 
hitherto been recorded from China or Japan. 
GRIMMIACEX. 
RHACOMITRIUM FASCICULARE, Brid—Japan: Kobe (C. Ford, 
Nov. 1890, no. 290).—These specimens differ from the usual 
form of the species in the stems having fewer branches, 
and in the leaves being longer and narrower above, and fre- 
quently denticulate at the apex; but, as Mitten (8) has already 
remarked, the differences are too slight to justify the separation 
in any way of the Japanese plant. 
PrycHOMITRIUM MICROCARPUM, Par.—Manchuria: M. Teien 
Mts., c. fr. (Dr. E. Faber, May 1891, no. 1507). Only known 
hitherto from the Prov. Schen-Si, China. To Müller's (11 & 13)
