very near, but differs in more distant, longer and narrower leaves, 

 more acute and without any border. 



F. firmus Mitt, is still nearer, but is a taller plant, with more acute 

 leaves, very stout nerve, and very strong border on the vaginant 

 lamina. No fruit is present on Mitten's type. It is possible that the 

 present plant may ultimately have to be united with it. It appears 

 to have been gathered in a more or less aquatic situation. 



Fissidens karwarensis. Dixon sp. nov. (fig. 4). 



E minoribus generis caulis 3-4 mm. altus, plurijugus, frondem 

 angustam, atro-viridem sistens. Folia inferiora parva, superiora multo 

 majora, laxiuscule disposita, deplanata, sicca fortiter falcato-incurva, 

 fragilia, oblongo-lanceolata, acuta ; lamina vaginans ad dimidiam 

 partem folii producta vel paullo ultra ; ea foliorum inferiorum 

 plerumque immarginata, foliorum superior um atque praecipue Roralium 

 fortiter limbata, limbo aliquando perlato ; lamina apicalis et dorsalis 

 elimbata, minutissimecrenulata, lamina dorsalis ad folii basin producta 

 ibique plerumque rotundata ; costa angusta, pellucida, subpercurrens, 

 vel in apiculum egrecliens. Areolatio perdensa, e cellulis minutissimis 

 papulosis instructa. Seta brevis, 2-4 mm., tenella ; theca minuta, 

 anguste elliptica, collo defluente, erecta vel leniter inclinata, sub ore 

 constricta operculo conico-rostrato, acuto. 



Dioicus videtur ; flores. haud visi. 



Hab. Stones, Karwar (6368), Bole of coconut palm in irrigated 

 spice garden, Shiggaon (3485). 



Near to F. ceylonensis Mitt, but that has -still more opaque and 

 obscure cells, narrower leaves, and dorsal lamina narrowed to base. 

 F. Treubii Fleisch, also is very similar, but the leaves there are 

 much longer, narrower and closer together. 



The border is rather remarkable, being entirely absent from 

 most of the leaves, but in the uppermost leaves of the fertile stems 

 well marked and even unusually broad. Even there however it is 

 highly variable and may be wanting.

Caules aggregati, vix caespitosi, rufescentes, simplices vel parce 

 ramosi, vix 1 cm. alti, multijugi, fusco-rubri. Folia, flavo-virides, laxe 

 disposita, complanata, patentia, sicca hand mutata vel minime depla-

 medium folium attingens, apice plerumque obtuso ; lamina dorsalis ad 

 folii basin producta, ibique crenulata, rotundata ; costa valida, pellu-
