 DICRANUM PHASCOIDES. 



Cryptogamia Musci. Nat. Ord. Musci. 



Gen. Char. Seta terminalis (Fissidentibus quibusdara exceptis). Pe- 

 ristomium simplex, e dentibus sedecim, bifidis, aequidistantibus. 

 Calyptra dimidiata. 



Dicranum phascoides ; caulibus laxe ca&spitosis simplicibus erectis, 

 foliis erectis subulatis integerrimis, nervo mediocri, capsula ob- 

 longa perichaetialibus immersa, operculo conico-acuuiinato, ore 

 annulate. (Tab. XXI.) 



Hab. Apud Sylhet Indiae Orientalis. D. Wallich. 



Caules subunciam longi, laxe caespitosi, erecti, flexuosi, simplices, ru- 

 bicundi. Folia undique inserta, erecta, subulata, omnino inte- 

 gerrima, laxe et obscure reticulata, tenuissime membranacea, 

 flavo-viridia, nervo mediocri ad apicem attingente instructa, floris 

 masciili vix nervosa, basi insigniter vaginantia, dilatata. Flores 

 utriusque sexus terminates. Capsula oblonga, basi sublatiore, 

 seta brevissima terminans, foliis perichsetialibus immersa, lavis, 

 fusca. Calyptra mihi ignota. Operculum brevi-conicum, ros- 

 tratum. Peristomium e dentibus 16, rubris, bifidis, erecto-pa- 

 tentibus, striatis, annulo pellucido e serie simplici cellulorum 

 constructo, cito deciduo, cinctis. 



I REGRET that I have not seen the calyptra of this very in- 

 teresting moss, which has so little the appearance of a Di- 

 cranum in its external habit, that, were it not for the very 

 perfect state of the peristome in the specimens sent, I should 

 scarcely have ventured to place it in that genus. Amongst 

 the Dicrana^ however, if such they still may be called, it . 

 comes nearest to that division which includes our D. Jlcx- 

 uosum ; but in them the calyptra is ciliated at the base, the 

 nerve of the leaf is broad, and the seta is of considerable 

 length.
