 Fronde ex tereti compressa, stipite inferne nudiusculo, superne ex 

 subraargine frondis ramulos subdistichos, superiores simplices lan-

 ceen (1901) pag. 215. — Fronde inferne et superne teretiuscula, 

 media parte complanato-dilatata, subplana et adparenter costata, 

 ainbitu obovato-lancoidea, parte superiore teretiuscula, ramis fili- 

 formibus a submargine exeuntibus corymbum terminalem fertilem 

 formantibus, infra apicem ramulorum cystocarpia singula, obovato- 

 globosa, subpedicellata, gerentibus.

 Frons usque ad decimetrum longa, parte dilatata folium aemulante 

 latitudine 2,2 millim. parum superante, omnino farcta, cellula cen- 

 trali conspicua ambitu magis rotundata, ex qua series cellularum 

 tenuiorum margines versus continuantur. his utrinque singula serie 

 cellularum majorum cinctis; extra has stratum adest corticale cel- 

 lulis minoribus fere duplicem seriem efficientibus contextum. Pars 

 superior ac teres frondis transversaliter secta monstrat intra lim- 

 bum gelatinosum cellulas G-7 (an potius, ut credit Falkenberg, tan- 

 tum 5 ?) in orbem circa centralem dispositas cellulasque corticales 

 multo minores quasi intra marginem hyalinum receptas.
