MUSCI AND НЕРАТІСЖ RECORDED FROM JAPAN. 191 
FISSIDENS, Hedw. 
196. Е. AprANTOIDES, Hedw.—. decipiens, De Not., et F. cristatus, Wils. ex Mitt. in 
Journ. Linn. Soc., Bot. iii. Suppl. 137. 
Small barren stems, * Challenger’ Етр.; fertile specimens, Oyama, Bisset. 
197. Е. saponrtcus, Dozy et Molk. 
* Challenger’ Exp.; and at Nagasaki by Oldham, all barren. Fertile by Матітотгісг. 
Like F. nobilis, Griff., and F. acutifolius, Mitt., this species has its leaves with a limb 
more or less distinct and finely serrate. 
Three other species (F. laxus, Р. incrassatus, and Р. pungens) are described by Sullivant 
and Lesquereux, p. 276, with characters insufficient for their recognition. 
ATRICHUM, Beauv. 
198. А. UNDULATUM, Beauv. 
In a state scarcely different from common European specimens, one fertile stem and а 
few without fruit, * Challenger' Етр.; in а state with narrower leaves, and with the 
inflorescence variable—Jokyo, Chiusenji, Jigoku-gawa, Hakodate, Fujisan, Nikko, and 
Ikao, Bisset. 
It is possible that this narrower-leaved state may prove distinct, although differences 
in other particulars have not yet been observed. А state in which the leaves on the 
lower portions of the stems are like those of 4. undulatum, but with the сота! leaves 
much narrower and more like those of 4. angustatum, was collected in the United States 
by Torrey and Drummond. 
199. A. ANGUSTATUM, Schimp., Polytrichum angustatum, Hook., is enumerated from Japan 
by Sande- Lacoste in Мід. Ann. Mus. Bot. Lugd. Bat. i.295. It may be the narrow- 
leaved state of 4. undulatum. 
OLIGOTRICHUM, DC. 
200. О. Lescuret, Mitt.—Atrichum Lescurei, James in Bull. Torrey Club, vi. 33; Les- 
quereux et James, Manual, 257. 
Nantaizan, Sept., Bisset. 
A very distinct species with sharply-toothed leaves, which have, towards the base on 
each side, a few of the teeth produced into hairs. The capsule is, when empty, turbinate ; 
the calyptra is small, smooth, and shining. It has no resemblanee to any species of 
Atrichum. 
POGONATUM, Brid. 
Sect. Anasmogonium. 
201. P. spryutosum, Mitt. in Journ. Linn. Soc., Bot. viii. 156. 
Nikko, Bisset. 
202. P. ALOIDES, Brid. 
With old fruit, ‘ Challenger’ Exp.; Joshin, Tokio, Hakone, &е., Bisset; and a state
