54 MR. MITTEN ON SOME NEW SPECIES OF MUSCI 



uoso rubro Isevi apice (sicco) rugiiloso ovali cernua ; operculo subulato cequilongo ; 



peristomio satis magno, dentibus medio linea pallidiore notatis valde trabeculatis 



crassis, interno processibus paulo longioribus solidis in membrana ad tertiam partem 



dentium longitudinis producta; calyptra superne scabra. 

 Hub. River Niger {Vogel) ; Nupe {Barter). 



Leaves narrower than in any of the described species ; seta smooth below, appearing slightly rough in 

 the upper part when dry.

FissiDENS, Hedw. 



F. VoGELiANUS, Mitten. Monoicus, caule brevi ; foliis patentibus elongate lanceolatis sic- 

 citate vix mutatis ubique tenuiter marginatis, lamina vera ultra medium producta, 

 nervo obscuro percurrente, cellulis distinctis iis laminae apicalis diametro cireiter 

 aoVo uncise mensura ; tlieca in pedunculo gracillimo quadrilineari suberecta ovali, 

 operculo subulato sequilongo, peristomio generis, flore masculo gemmiformi ad pedem 

 rami foeminei. 



Hab. River Niger (Fo^e^). 



A small species agreeing in size and habit with the Javan F. ZoUingeri, but with leaves of a firmer 



substance, of an obscure olive-brown colour. 



Tab. V. fig. 10. 1. Plant (natural size) ; 2. the same, and 3. a leaf (magnified). 



E. oPACiFOLius, Mitten. Monoicus, caule brevi ; foliis patentibus late lanceolatis acutis 



siccitate non mvitatis, lamina vera ad medium producta subinsequali crassiuscule 

 hyalino-marginata, lamina apicali latiuscula dorsalique tenuiter crenata, cellulis opacis 

 obscuris, nervo pellucido luteo percurrente ; theca in pedunculo bilineari ovali erecta, 

 operculo subulato, peristomio generis, calyptra basi Integra papillosa, floribus masculis 

 gemmiformibus in foliorum caulinorum axUlis reconditis. 

 Hab. River Niger {Vogel); Natal {Guenzius). 



The opaque rather broad leaves, pellucid nerve, and strongly margined border of the true leaf distin- 

 guish this species from its allies. The calyptra resembles that of F. serratus from the Nilgiri Mountains.

F. EAMTJLOSUS, Mitten. Dioicus ? caule fertili brevi, ramis gracilioribus e basi egredientibus 



ramoso ; foliis patentibus siccitate crispatis lanceolatis immarginatis, lamina vera ad 

 medium producta apice subincequali, nervo subpellucido percurrente, marginibus 

 ubique tenuiter crenatis, cellulis minutis obscuris diametro 4xnro ^^ncife metientibus ; 

 tbeca in pedunculo trilineari gracillimo ovali erecta, operculo subulato, peristomio 

 generis, calyptra basi Integra Isevi. 



Hab. River Niger {Vogel). 



Allied to F. elegans, Schw., but with a different habit. From F. opacifolius it differs in the absence of 



margin to the true leaves, as well as in their form and in the inflorescence, and also in the smooth calyptra.
