Tab. 2.
Plantæ permagnæ, aquatictc, molles, partibus junioribus emersisque glauco-viridibus, immersis pallide fuscescentibus.
Caulis pedalis 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 clavæformibus erecto-vel arcuato-patentibus, cæteris gracilioribus longioribus laxioribus deflexo-dependentibus; cellulis strati corticalis 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, cætera 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 cellularum dissolutarum lineis commisuralibus (membrana plus minus destructa) compositis; cellulis hyalinis inferioribus elongatorhomboidalibus ad latera intus papillis numerosis (fibrillis abortivis?) instructis, superioribus rhombeis, omnibus fibrillosis et porosis; cellulis chlorophyllosis ad folii faciem concavam positis, transversimque sectis triangularibus.
Flores et fructus desiderantur.
