156 МВ. W. MITTEN ON THE SPECIES OF 
foliage is sometimes straight and erect, simply patent, or, as 50 commonly in the allied 
species, faleate and secund; in all the specimens it is yellow or fulvous. 
7. DICRANUM SCOPARIUM, Hedw. 
Chiusenji, with perfect fruit in September; and the variety (D. Venturi) with older 
fruit in May, Fujisan, Yumoto, Bisset. 
8. D. сжатом, Sp. n. Caules laxe czespitosi erecti simplices furcative, interrupte foliati, 
radicellis brevibus sparsis vestiti. Folia patula ssepius arcuato-incurva, interdum 
faleata, apicalia in penieillum erectum арргезза, apicibus liberis, omnia inferne 
anguste elliptica fere a basi sensim angustata canaliculata, nervo crasso concolori 
dorso ubique minute aspero fere ad apicem angustissimum a pagina distincto, mar- 
gine crenulato-serrulata, cellulis superioribus parvis ovalibus, basin versus longiori- 
bus, dorso minutissime scabris, alaribus paucis pallide fuscis. 
Nikko, Bisset. 
Caulis 4-uncialis. Folia longiora 1 cm. longa, superiora pallide glauco-viridia nitoris 
destituta, ob nervi crassitudinem satis rigida, sicca, varie flexa, nonnulla circinata. 
In its glaucous foliage unlike any of the other Japanese species, and comparable only 
to the N. American D. Drummondii, with which it agrees in the substance of its leaves 
and scabrous nerve; but in D. cesium the leaves are much narrower, and the nerve in 
proportion wider and thicker. 
9. D. сохвевтт/м, Brid. 
Shiranesan, Yumoto, Bisset. 
Sect. Orthocarpa. 
10. D. FLAGELLARE, Hedw. 
Nantaizan, with fruit not quite mature in September, and Fujisan, Bisset. 
11. D. HAMULOSUM, sp. п. Dioicum. Caulis simplex furcatusve, inferne tomento sub- 
albido inter folia obtectus. Folia secunda falcata, a basi supra cellulas alares fusci- 
dulas sensim angustata carinata, nervo inferne + folii latitudinis occupante ubique а 
pagina usque ad apicem distincto, dorso minute denticulato-scabro, marginibus supra 
medium ad apicem serrulatis, cellulis basalibus elongatis, superioribus parvis rotun- 
datis areolata; pericheetialia dimidio inferiore vaginantia, subito angustata. Pedun- 
culus gracilis. Тһеса oblongo-ovalis erecta æqualis striata, operculo subulato æqui- 
longo. Peristomium dentibus breviusculis, annulo simplici. 
Barren stems, ‘Challenger’ Exp., Maries; and with fruit, Nantaizan, Bisset. 
Caules 2—4 ст., albi, fusco-rubri. Folia 5-8 mm. longa, sicca, parum mutata, viridia 
fuscescentia vix nitentia. Pedunculus pallidus, 1 сш. longus. Theca cum partie 
4 mm. longa. 
Size and appearance that of D. Sauteri; but different in the narrower, more indurated 
nerve, and in areolation, as well as in the striate capsule ; more robust thái D. montanum.
