China: “ West Szechuen and Tibetan Frontier, chiefly near 
Tachienlu, at 9000-13,500 ft." (A. E. Pratt, no. 758). 
Hitherto known only from Sikkim. 
POLYTRICHUM COMMUNE, Linn.—China: Hupeh, S. Patung, 
c. fr., form with the margin of the lamina more or less ineurved (Dr. 
E. Faber, no. 7408); Tientai Mt., 3560 ft., Prov. Chekiang, c. fr. 
(idem, 1889, nos. 11, 17) ; on ground in wood, Hupeh, Chienshih, 
c. fr. (Dr. A. Henry, 1888, no. 5817). 
ÖLIGOTRICHUM LESCURIT, Mitt. 
This species, recorded by Mitten (8) from Japan (Nantaizan, 
Bisset), was origiually found by Kellogg in Alaska, and deseribed 
by James (Bull. Torrey Bot. Club, vi. 1875, p. 83) as Atrichum 
Lescurit. Hitherto Alaska and Japan have been the only locali- 
ties known for the plant; I find, however, from specimens in the 
Kew Herbarium, that the barren moss from Kamtchatka, which 
in Hooker and Arnott's Bot. of Beechey's Voyage, p. 119 (1841), 
is referred doubtfully to Polytrichum contortum, really belongs 
to O. Lescurii. This occurrence of the species in the inter- 
mediate station of Kamtchatka is very interesting, as helping 
to explain the present geograph‘cal distribution of the species.
