 superante), segmentis sequentibus triplostiehe corticatis, ultimo 

 brevissimo ecorticato inucroniformi; foliola omnium geniculorum 

 verticillata, sterilium brevissima, fertilium interiora magis elon- 

 gata, sporangium subsequantia, geniculi infimi sterilis conformia; 

 slipulae in coronam duplicem seriatge, seriei superioris longiores, 

 foliorum articulum infîmum occultantes; sporangia ab antheridiis 

 sejuncta (diversis geniculis ejusdem folii imposita), oblonga,

« InNova GranataadChipaque prope Santa Fé de Bogota, altitudine'cir- 

 citer 1500 hexapodum in consortio Potamogelonis cujusdam angustifolii 

 legit D r H. Karsten. » Eodem locoin stagno etiam lecta fuit a cl. Triana 

 (sed altitudine indicata 2000 metr.). 



Obs. — Cel. Al. Braun eam speciem tenuiorem gracilioremque dicit 

 quam omnes formas Charœ polyphyllœ, prseterea eandem vix ne minime 

 quidem incrustatam observari, inde minus esse fragilem, coloris dilute vi- 

 rentis vel sordide flavo-virentis et nitoris obsoleti. Obiter visa accedit ver- 

 sus formas tenuifolias europseae Charœ fragilis. In stirpe Gymnopodarum 

 maxime eminet antheridiis sporangiisque sejunctis, quaa licet in eadem 

 planta et iisdem foliis nascentia tamen non in eodem geniculo occurrunt. — 

 Notare hic simul liceat ex opère Brauniano citato Characeas, quaa in ceteris
