Plantae pusillae, lineas 2 circiter altitudine metientes, subsimplices, 

 gregarie caespitosae, caespitibus laete viridibus planiusculis , radiculis 

 plurimis laxe cohaerentes. 



Folia erecto-patentia, apice paullo incurva, inferiora minora, supe- 

 riora sensim majora inque comam paucifoliam congesta , exsiccando 

 varie torta, spathulato-lanceolata, marginibus superne incurvis inferne 

 involutis, concava, integerrima, costata, costa validiore flavida cum vel 

 paullo sub apiculo desinente; areolatione densissima subopaca e cellulis 

 minimis, hexagono-subquadratis, chlorophyllo obrutis, versus foliorum 

 basin sensim majoribus et laxioribus, basilaribus maximis elongate qua- 

 dratis chlorophyllo destitutis limpidis. 



Florescentia rnonoica. Flos masculus in ramulo proprio basilari, in- 

 ferne nudiusculo, superne comose folioso. Folia perigonii valde concava, 

 basi convoluta, lanceolato-acuminata, erecta, integerrima, costata, costa 

 valida ante apicem evanida. Antheridia plurima, cylindrica, paraphysi- 

 bus filiformibus longitudine subaequalia. Flos femineus terminalis, soli- 

 tarius : folia perichaetii exteriora comalibus similia, erecta ; intima duo 

 duplo breviora, cylindraceo-convoluta, laxius reticulata, praeter apicem 

 obtusiuscule rotundatum hyalina, costata, costa evanida vel obsoleta. 



Fructus terminalis, ratione exilitatis plantae alte pedicellatus. Pedi- 

 cellus e vaginula cylindrica capillaris, laevis, exsiccando tortilis, 0,008 

 0,01 altus. Capsula erecta, in pedicellum attenuata, cylindrica, recta 

 vel parumper curvata, versus orificium paullo angustata, fusca, laevis,
