 denique fuscescentes; caulis latiuscule complanatus in ramulos similes 

 breves aggregates obtusiusculos pinnatim divisus; folia caulina dense 

 imbricata valde undulato-rugosa madore perfecte disticha, e basi 

 angustiore in laminam majusculam oblongam ligulato - acuminatam 

 exeuntia, ad acumen breve acutum tenuiter serrulata, nervis binis 

 angustis pallidis longis exarata concava, margine erecta, e cellulis 

 brevibus ellipticis basin versus parum longioribus angustis reticulata;

 calyptra pallida glabra. Caetera nulla. 



Habitatio. Brasilia, Rio de Janeiro, Mte. Corcovado, ad ligna 

 putrida, Julio 1873, c. fr. supramaturis: Hj. Mosen in Hb. Brotheri, 



qui misit 1889. 



Ex habitu Hookeriae latifrondeae, sed foliis ligulato-acumi- 

 natis atque reticulatione densiuscula jam longe diversa, Hookeriae 

 Caldensi Angstr. proxima, sed haecce species surculo angustiore 

 purpurascente, foliis grossius serratis purpureo-nervatis jam primo 

 visu recedens, 



Var. major, fronde latiore in surculo distinctius remote pinnato. 

 Peristomium externum rubiginosum. 



Habitatio. In eodem loco ad ligna putrefacta: Ibj. Mosen 1873.
