 vel ovato-lanceolata, mucronata, 1.4 — 1.55 mm. longa et 0.55 mm. lata, 

 margine plus minusve late reflexo seriebus 2 — 3 cellularum elongatarum 

 limbata, cellulis marginalibus fuscis bistratis, ceiluiis basilaribus fuscis 

 elongato-rectangulis, illis folii medii rectangulo-rhombeis, 0.03—0.06 mm. 

 longis et 0.02 mm. latis, apicalibus hexagonis, omnibus valde incrassa-

 laris, semiovata, ovo longitudinaliter dimidiate similis, latere versus setam 

 spectante applanato, et sicca et humida immutata. GoUum duas qvintas 

 sporangii longum, in illud sensim transgressum, contia setam abrupte 

 definitum. Cellulse epidermicse sporangii irregulares, valde incrassat*, 

 elongato-rectangulee et qvadratee cum ovalibus mixtse, marginales in serie- 

 bus tribus minores transverse rectangulee, parietibus maxime incrassatis.
