 dense conferta minutissime papillosa carinata crispula madefacta patentia- 

 erecta lanceolata apiculata evanidinervia, margine plana v. parnm recurva, e 

 cellulis parvis incrassatis areolata. Theca ovalis in pedunculo 5rm erecta 

 sulcato-striataj operciilo conico suboblique-rostrato. 



Crowded, erect, very slender, branched. Leaves crowded, minutely 

 papillose, keeled, crisped (when moistened patentia-erect), lanceolate, apicu- 

 late^ nerve vanishing, margin flat or slightly recurved. Areolae small. 

 Capsule oval, erect, striate, on a short fruit-stalk. Operculum conical with an 

 oblique awl-shaped beak. 



5. Gymnostomum areolatum, n. s. 



Gregarium brevissimum, folia concava laxiuscula crispula madefacta 

 erecto-patentia elongato-ohlonga v. suhspatulata apiculata v. acuminata, ubique 

 e cellulis amplis pellucidis tenuissime papillosis superne rotundato-angulatis v. 

 quadratis areolata, nervo ad apicem fere extimum perdurante. Theca ovata in 

 pedunculo brevi erecta, operculo conico suboblique rostrato. 



Plants crowded, stem very short. Leaves concave, lax, crisp, when mois- 

 tened erecto-patent, elongato- oblong or subspatulate, apiculate or acuminate j 

 areolae throughout large, pellucid, papillose, towards the point rotundato- 

 angular, nerve extending to the apex. Theca ovate, erect, on a short fruit- 

 stalk, operculum conical with an oblique beak. 



6. Gymnostomum angustatum, n. s. 



Plantse humiles. Folia madefacta patentia curva papillosa linealia ohtusa, 

 margine erecta, nervo dorso prominente infra apice evanido. Theca erecta 

 ovalis ; operculum e basi conica in rostrum subulatum continuatum. 



Plants small. Leaves (when moistened, spreading, curved), papillose, 

 linear, obtuse, margin erect, nerve prominent at the back, vanishing below
