 — Frons ancipiti-plana, margine irregulariter denticulata, vage 

 furcatim divisa, evolutione ramorum furcse iiucquali, raro margine 

 passim prolifera. Stratum medullare e filis longis constans, axi cen- 

 trali tenui verticillatim ramoso; cortex angiistus, introrsum grosse et 

 laxe, extrorsum minute denseciue cellulosus. Cellula apicalis trans- 

 verse divisa. Cystocarpia solitaria, per frondis totam superficiem 

 sparsa, inter stratum meduUare corticemque nidulantia et corticem 

 tumefacientia. Nucleus ut in Pikea, sed multo major, cortice supra 

 nucleum poro pertuso. Sporatigia (ut videtur) ol)liquo cruciatim 

 divisa, in nematheciis parvis, planis, per frondis superficiem sparsis 

 nidulantia.
