MUSCI AND НЕРАТІСЖ RECORDED FROM JAPAN. 167 
nitida, chartacea, marginibus siccitate undulatis, limbo tenui concolore indistineto pul- 
cherrime ciliato. 
This fine Moss differs from all known species of the genus in its stiff, thin, shining 
foliage, which does not curl up in drying and has thus no near resemblance to 
M. undulatum. 
The nerve, with its numerous lateral branches vanishing in the substance of the leaf, 
is a singularly remarkable character, but the arrangement of the cells in curved lines 
ascending from the nerve obliquely to the margin is to be seen also in M. cinclidioides. 
Barren stems are present among the fertile and appear to grow erect, the apices with 
leaves decreasing in size. 
76. MNIUM ACULEATUM, sp. n. (Plate LI. figs. 10-13.) Dioicum. Caulis fertilis gracilis 
simplex, inferne radicellis nigrescentibus obtectus. Folia inferiora et in caulibus 
sterilibus ovalia late obovataque, in acumen breve angustata, marginibus breviter 
paucidentatis, comalia patentia majora obovato-oblonga longius acuminata, nervo 
sub apice desinente, marginibus inferioribus recurvatis, inde ad apicem acutum usque 
serraturis acutis aculeiformibus simplicibus, limbo e seriebus tribus cellularum соп- 
dito cartilagineo, apice in mucronem pungentem confluente, cellulis parvis 5-6-gonis 
marginem versus minoribus areolata. Тһеса ovalis nutans, evacuata sub ore con- 
stricta, basi collo brevi, flexura angusta іп pedunculum transiens. 
Chiusenji, Aug., Bisset. 
Caulis fertilis uncià brevior. Folia inferiora 2 mm., comalia 4 mm. longa, ubi 
latiora 1 mm. vix excedentes, sicca parum crispata, dentibus marginalibus e tribus cellulis 
compositis, spatiis intermediis subsinuatis. Peduneulus 4 ст. longus.  Peristomium 
dentibus ceraceis, internum fuscum. 
77. M. UNDULATUM, Hedw. 
Recorded by Dozy and Molkenboer (Muse. Frond. Archip. Ind. p. 28), by Van der 
Sande-Lacoste, and by Lindberg, in a sterile state only, from Sennano, ins. Nippon. 
78. M. МАхтмоутолтт, Lindb. in Act. Soc. Sci. Fenn. x. (1872) р. 224. 
A smaller species with linguiform oblong leaves, emarginate at the apex, with from 
one to six setæ arising from the same perichzetium ; it is fully described and ana 
to М. undulatum. It was gathered at Yokohama ; also 
79. M. sapontcum, Lindb. /. с. 226. 
With rhombo-obovate long acuminate leaves, having the margins recurved from the 
base to the middle and thence to the apex fimbriato-ciliate ; it is compared to M. medium, 
and came from Fudzi, ins. Nippon, gathered by Maximowicz. The description agrees 
with the leaves of M. aculeatum, which appears to be very much smaller.
