Gen. Char. Seta terminalis. Peristomium simplex; mem- 

 hrana horizontalis ex integumento interno orta, in ciliolis 

 subtilibus subramosis fissa- Calyptra dimidiata? 



Schizymenium bryoides. 



Habitus Bryi^ praecipue B. elongati. Caules uncialesj ramosi, 

 dense caespitosi, inferne copiose radiculosi; rami erecti, 

 foliosij superne dilatati. Folia erecta; laxiuscule imbricata, 

 lato-lanceolata, acuminata, membranacea, subscariosa, nitida, 

 flavo-viridia, laxe reticulata areolis oblongisj margine superne 

 serrata. Seta terminalis, S-e-lineasIonga, erecta, apice curvata, 

 laevis. Capsula inclinata, subhorizontalis, oblongo-subpyri- 

 formis, pallide flavo-fusca, laevis, ad orara non contracta. 

 Operculum fere exacte conicum seu conico-convexum, acutum. 

 Annulus magnus maxime cellulosus, operculo delapso cito 

 deciduus. Peristomium simplex, e membrana interna ortum, 

 horizontale, reticulata, in ciliolis 1 6 gracilibus articulatis parum 



ramosis fissa. 



Whether the structure and direction of the fringe of this new 

 Moss, are sufficient to constitute a Genus, distinct from some of 

 the other single-peristomed BryoidecB, may admit of a question. 

 Indeed, notwithstanding all that has been done of late years in 

 the beautiful Order of Muscij only serves to show us how much 

 yet remains to be done before the limits of the Genera can be 

 so defined as to afford a satisfactory and natural arrangement.
