Monoicum laxe caespitosum; folia rnadida 11011 reflectentia 
erecto-patula subsecunda, siccitate laxe appressa, oblongo- 
lanceolata acuminata carinata, margine basin versus revo- 
luto, basi dense longiuscule reticulata, superne e cellulis 
irregulariter rotundatis tenuiter papillosis areolata, evanidi- 
uervia; folia pericliaetialia conformia submajom; tlieca exserta 
oblonga estriata laevissima ochracea; calyptra fusca thecam 
obtegente parce pilosa; dentes peristomii externi 8 bigemi- 
nati, apice appendiculati trabeculati; cilia 8 subaequantia 
irregulariter articulata punctulata. 
Caespites lati inordinati fusco virides. Caulis 1—2 centim. 
longus rigidulus, irregulariter dichotome ramosus ad basin 
rufo-radiculosus densifolius. Folia, quae madida subito non 
reflectuntur moxque deinde eriguntur, fusco viridia breviter 
decurrentia e basi erecta erecto-patentia, sicca subappressa 
oblongo-lanceolata acuminata, margine basin versus revoluto, 
carinata, nervo crasso infra apicem dissoluto, cellulis basi- 
laribus hyalinis laevissimis densis rectangularibus, mediis 
cylindricis incrassatis et supremis subrotundis papillulosis; 
perichaetii folia paulo majora, longius nervosa, subplicata. 
Vaginula oblongo-cylindrica archaegonia et paraphyses pau- 
cissima gerens. Seta 2,5—3 millim. longa, fusca. Capsula 
exserta ochracea oblonga estriata, laevissima. Peristomium 
majusculum albido-luteolum, duplex, dentibus 8 bigeminatis, 
siccis reflexis trabiculatis, apice appendiculatis, ciliis 8 sub- 
aequilongis irregulariter articulatis punctulatis. Calyptra 
magna totam capsulam fere obtegens fusco-straminea, apice 
fusca parce pilosa. Flores masculi in vicinitate faeminei 
plures, fuscescentes, foliis ovatis concavis breviter et obtuse 
acuminatis; antheridia pauca.
