contortum has hitherto been recorded from British Columbia, 
California, and Alaska, and in Asia from Dui, Saghalien. 
POLYTRICHUM SPINULOSUM, Afitt—China: Tientai Mt., 3000 
ft., Prov. Chekiang (Dr. E. Faber, 1889, no. 20). New to China ; 
originally recorded from Japan (Nagasaki), and there are other 
Japanese specimens in the Kew Herbarium from Miyanoshita 
(C. Ford, 1890, no. 297), also from Yokoska, Nippon (Savatier, 
1878, in Schimper’s Herbarium under the MSS. name of 
Pogonatum acaule, Schimp.). 
The leaves of this interesting species are entirely without 
lamellae. Mitten (7) considers the plant nearest to P. Gardneri, 
Jaeg. of South Ameriea, and in habit, shape and areolation 
of the leaves the two species certainly show affinity ; it may be 
observed, also, that in some leaves of P. Gardneri the lamellæ 
become very low or even obsolete. Even closer, however, to 
P. spinulosum is P. abbreviatum, Mitt., another S. American 
species, as in this moss some leaves are quite destitute of lamelle. 
Although P. spinulosum is thus evidently too closely allied to 
other species to be placed in even a separate section of the genus, 
on the other hand it tends, by the total absence of lamelle, to 
approach the genus Rhacelopus, which seems, however, distinct 
in the different type of areolation and in the rough seta. 
The plant described as a new species, under the name of Pogo- 
natum pellucens, by Bescheielle (18. p. 351), is the present species. 
Bescherelle remarks: “ D’après la diagnose qu'en donne l'auteur, 
notre mousse aurait de grandes affinités avec le P. spinulosum 
Mitt. de Nagasaki; les feuilles rigides non incurvées, entiéres de 
la base à la partie cuspidée et non dense spinuloso-dentata, Yen 
éloignent suffisamment." Mitten’s description of the leaves as 
“‘spinuloso-dentata” applies more especially to the minute lower- 
most leaves, the margin of which is irregularly cut to below the 
middle; the upper leaves are entire from the base to near the 
euspidate apex, where the margin as wellas the excurrent nerve 
become spinulosely dentate.

Fau Shan, c. fr. (C. Ford, Aug. 1883, no. 82). 
In some examples of this species from Java, in Schimper’s 
Herbarium, the leaves have a serrate base, and the capsule is 
papillose (see Dozy & Molkenb. Bryol. Jav. p. 44, tab. 34. figs. 14,
