 inferiore radiculis fuscis lævibus instructus. 



Caulis 0.25 mm. crassus, fuscus, sectione pentagonus, alatus, 

 rete centrale tenue, laxum, leniter collenchymaticum, haud poro- 

 sum, subito in seriebus tribus externis valde incrassatum, parce 

 porosum, hic illic infra folia strato cellularum tenuium tectum. 



Folia caulina densa, sicca adpressa, humida primum decur- 

 vato-squarrosa, dein patentia, inferiora ca. 1 mm. longa et 0.38 

 mm. lata, superiora 3 mm. longa et 0.65 mm. lata, ovato-lanceolata, 

 sensim angustata, acutiuscula — obtusula, margine late recurva 

 — revoluta, in parte media sulco mediano instructa, apice magis 

 explanata, basi fusco-lutea; cellulæ mediocriter incrassatæ, basales 

 inanes, mediæ rectangulæ ad 0.04 mm. longæ et 0.014 mm. latæ, 

 parietibus interdum sinuosis, angulares et suprabasilares subqua- 

 dratæ, ca. 0.012 mm. latæ; illæ folii superioris chlorophyllosæ, 

 rotundatæ, ca. 0.011 mm. magnæ, papillis congestis altis pro more 

 bipartitis obsitæ; costa basi 0.08 mm. lata, fusco-virens, in apice 

 sensim dissoluta, sectione plano-convexa, inferne dorso angulata, 

 stratis cellularum mediocriter incrassatarum basi 4 apice 3 compo- 

 sita; cellulis ventralibus 2. 



Inflorescentia autoica. 



Flos masculus origine terminalis, demum lateralis vel in bifur- 

 catura caulis situs, minutus ; folia perigonialia 2, concava, late

 enervia; antheridia 6—8, in stipite duplice cellularum serie formato, 

 0.38 mm. longa, 0.08 mm. crassa ; paraphyses fere totidem, paullo 

 longiores, filiformes, vix luteolæ. 



Folia perichætialia erecta, basi caulinis latiora et in tractu longi- 

 ore hyalina ; pistillidia ca. 6, 0.28 mm. longa, paraphysibus nullis. 



Vaginula ovato-conica, 0.56 mm. longa, 0.36 mm. crassa,
