MUSCI AND НЕРАТІСЖ RECORDED FROM JAPAN. 163 
sensim angustata, usque ad basin thece ovalis lzevis producta. — Peristomium e den- 
tibus teneris brevibus. Calyptra ramentis densissime vestita. 
Kintoki, Bisset. 
Ceespites laxi. Каті appressifoliati 3-5 ст. longi, ramulis sspe brevissimis, statu 
humido stellatim foliatis. Folia longiora 2 mm. longa longiorave. Тһеса 2 mm. longa, 
in pedunculo zequilongo, cinnamomea, ore carnosula intensiore colorata. 
Тһе habit of this species is quite different from that of the preceding ; instead of the 
stems being creeping with aggregated erect branches, they seem merely procumbent and 
thus form a loose tuft.

Kintoki, Hakone, Bisset. 
In this species the short branches are aggregated into extensive patches. The calyptra, 
although that of the genus, is split more on one side, and, with some other species in 
which the calyptra is found in the same condition, has been enumerated by Lindberg, 2. с. 
р. 229, as belonging to Dasymitrium, М. rupestre and М. incurvum being also included. 
52. M. incurvuM.—Dasymitrium incurvum, Lindb. in Seem. Journ. of Bot. 1864, p. 385 
(M. japonicum, C. Muell. Syn. i. 740). | 
C. Mueller received specimens of this mixed with M. japonicum, and thus described the 
wrong species (Miquel, in Ann. Mus. Bot. Lugd. Bat. ii. 294; Prolusio, 182). 
53. М. соматтм, sp. п. Humilis, laxe ezespitosus. Caulis fertilis ramosus, foliis paten- 
tibus diversimodo curvatis, a basi parum latiore lineali-elongatis, apice latis, obtuse 
acutis, ѕере incurvis, margine papillis prominulis minute erosis, nervo flavo carinatis, 
cellulis superioribus obscuris, inferioribus pellucidioribus, infimis paucis ad nervum 
oblongis areolatis ; perichzetialibus brevioribus lanceolatis erectis. Theca in pedunculo 
brevi, basi ramentis elongatis exsertis, oblonga, operculo conico brevirostro. Calyptra 
magna, thecam totam obtegens, ramentis, fulvis erectis elongatis copiosis vestita. . 
Umagayeshi to Chiusenji, in-loose tufts with Lasia fruticella and Anomodon tristis ; 
fruit immature in September, Bisset. 
Rami fertiles 1-2 ст. alti, cum foliis humidis 3 mm. lati. Folia 3 mm. longa, inferiora 
fusca fulvave, superiora viridia, sicca laxe crispata. Pedunculus 2-3 mm.longus,angulatus, 
flavidus. Тһеса cum operculo 2 mm. longa, plicata (?), immatura. Calyptra a basi ad 
apices ramentorum 4 mm. longa. 
In its short seta and very ramentose calyptra this resembles JM. prolongatum ; hu its 
stems are shorter and not so diffused, its leaves are not so narrowed towards their 
more obtuse points, and they are more obscured with papille ; the perichzetial leaves are 
very different, much shorter than those of the stem, so as to be inconspicuous, whereas 
in M. prolongatum the perichzetial leaves reach to the neck of the capsule and are as long 
as those of the stems. f 
The fruit is too immature to show the carnose mouth so characteristic of this section, 
but in all other respects it corresponds.
