 Tab. 2. 



Plants permagnac, aquatictc, molles, partibus junioribus emer- 

 sisque glauco-viridibus, immersis pallide fuscescentibus. 



Caulis pcdalis et longior, simplex vel bipartitus, crassiusculus, 

 firmus, brunnescens, corticc spongioso triplici vel quadmplici e 

 cellulis hyalinis spirali-fibrillosis vix porigeris formate- obtectus : 

 ramulis 4-5 in fasciculo, 2-3 julaceo-foliosis basi attenuatis 

 clavaeformibus erecto- vel arcuato-patentibus, cseteris gracilioribus 

 longioribus laxioribus deflexo-dependentibus ; cellulis strati cor- 

 ticalis simplicis geniculatis spiraliter fibrillosis parce porosis. 



Folia basi appendiculata quasi stipulata; caulina subquadrato- 

 ovata, erecta vel deflexa; cellulis hyalinis vix vel parcissime 

 fibrilligeris sine ullis poris : ramulorum patulorum folia dorso 

 ad apicem valde cucullatam squamoso-scabra, basilaria parvula 

 semicircularia, caetera ampla basi brevissime angustata, media 

 orbiculato-ovata, superiora late oblonga angustissime marginata, 

 omnia (terminalibus exceptis) arete imbricantia, toto ambitu 

 (sicut caulina) eleganter fimbriata, fimbriis varie flexis e cellu- 

 larum dissolutarum lineis commisuralibus (membrana plus mi- 

 nus destructa) compositis; cellulis hyalinis inferioribus elongato- 

 rhomboidalibus ad latera intus papillis numerosis (fibrillis abor- 

 tivis ?) instructis, superioribus rhombeis, omnibus fibrillosis et 

 porosis ; cellulis chlorophyllosis ad folii faciem concavam positis, 

 transversimque sectis triangularibus. 



Flores et fructus desiderantur.
