160. Hypnum Punuw, Linn., is reported sterile from Siebold. 
161. Н. PRÆLONGUM, Linn. 
А few stems amongst other Mosses, * Challenger’ Exp. With deoperculate capsules 
in February, Maries. 
Н. prelongum is a species of very wide distribution, and is found in N.W. America 
with its capsules abruptly bent down and more or less evidently ventricose, as is usual 
in European specimens; but in the few plants seen from Japan the capsules have a 
different appearance, being only a little inclined and not ventricose, and the leaves of the 
main stems are not divergent ; in other particulars they correspond with the usual states. 
H. hians, Hedw., gathered in fruit by Thunberg, and sterile by Teztor, is mentioned 
by Sande-Lacoste. 
162. Н. rornysTICTUM, sp. n. Dioicum. Caulis procumbens, pinnatim ramosus. Folia 
laxe patentia patulave, caulina cordato-ovata, sensim in acumen angustum subu- 
latum producta, ramea compressa ovata vix acuminata, apice latiuseula acuta plani- 
uscula, nervo infra apicem in denticulo dorso exstante producto, margine ubique 
serrulata, cellulis angustissimis apicibus in punctis dorso elevatis productis. Peri- 
chætium magnum, foliis internis in subulam angustam elongatam recurvam minus 
serrulatam eductis. Pedunculus elongatus, ubique asperrimus, apice arcuatus. 
Theca horizontalis cernuave oblonga, operculo subulato-rostrato. Peristomium 
normale. 
Received amongst packing material with Diospyros Kaki. 
Caules triunciales longioresve, ramis semiuncialibus strictis curvatisve. Folia fusco- 
viridia subnitentia, siccitate parum mutata. Pedunculus sesquiuncialis, fusco-ruber, 
crassiusculus. Тһеса basi inzequalis fusca. 
Near to the Hypnum oreganum, Sulliv., from N.W. America; but less densely pinnate, 
with narrower leaves, and the capsule not ovate and pendulous. It is also nearly allied 
to Н. Swartzii, Turn., in size; but different in its interruptedly Рания arcuate stems 
and the form of its nios leaves. | 
168. Н. LONGIFOLIUM, вр. п. Habitus staturaque H. longirostri, foliis autem caulinis a 
basi subovata plicata sensim late subulatis, apice angustissimis, nervo ante subulam 
planiusculam evanescente, margine serrulata, rameis ovato-lanceolatis argutius 
serrulatis, omnibus e cellulis angustis areolatis. 
One stem only, Bisset; fragments from Tsus Sima, Wilford. 
Closely resembles И. longirostrum; but its leaves are 3 mm. long, with almost 
capillary points.
