F. fronde fimphci enfiformi bail rotundata ; flipite alato qua- 

 drangulari. 

 Fucus fimbriatus. Gmelln,p. 200. t. 29. f. i. 

 Radix fibrofa — Stipes inferne teres nudus, mox tetragonus mem- 

 brana lata membranacea, bafi rotundata ornatus — Anteaquam mem- 

 brana incipit, foliola f. frondium novarum quafi rudimenta diftiche 

 proveniunt — Hxc foUola circiter 12 aut plura, conferta, fubcartila- 

 ginea funt et enervia, pro magnitudine plants minora, longiora, 

 2 — 6 uncialia et ultra.

Omnia quae priori et huic accidunt, praeterquam quod in hoc

 branam ne minime quidem tetragonus, at teres et compreffiufculus. 

 Porro foliola ad bafin membranae, membranacea funt nee cartilagi- 

 nea. From in utroque maxima, longiflima, rncdo pedalis, fsepe 

 ijltra humanam altitudinem — At tehagonus longe major evadit. 



We are in doubt to which of thefe fpecies we ftiould apply the
