60. FUCUS SUBFUSCUS. 



F. fronde filiformi ramofiflima, ramis fparfis, ramulls fubulatis 



fub-alternis ; tubercuUs racemofis fub-odtofpermis. 

 JISl. Soc. Linn. I. p. 131. t. 12. Withering^ vol. T,.p. 236. 

 Habitat in rupibus et faxis fub-marinis in littore Icenorum. 

 Radix fibrofa — Frons fihformis, teres, ramofiflima, fubfufca, femi- 

 pellucida, femipedaUs, craflitie fiU emporetici — Rami fimiles plurimi 

 fparfi ; ahis paulo tenuioribus et apicem verfus confertis, iterum ra- 

 mofi — Ramuli fubulati, fub-alterni, tenuiffimi ; in quorum aUs et 

 ad latera, racemi breviflimi, tuberculis minutiflimis lanceolatis pal- 

 fidis— In tubercuUs fmgulis, femina fex vel oSto fphasroidea fub- 

 fufca, bino ordine difpofita. 



This fpecies is fufficiently difl:inguifhed from all its affinities by 

 its fingular frudlification ; and as an ample hiftory of it has been 

 given in a former volume of thefe Tranfadions, little need be added 

 here. 



It may neverthelefs be proper to obferve, that later and more 

 particular ohfervations have induced us to conclude that the pe- 

 duncle more conftantly approaches the form of a raceme than that 

 of a panicle, and that the extreme ramifications cannot with pro- 

 priety be confidered as leaves, fince they do not differ in fubftance 

 or in fhape from the reft of the plant. Thefe circumftances have 

 occafioned it to be neceffary, to make fome alteration in the fpecific 

 charafter as formerly given, and to place it in the divifion fronde 

 tereti, inftead of foliis utiitis, as before propofed.
