As Linnasus has taken no notice of this plant (F. corymh'fcrus of 

 GmeJin is his crijlatus), we necefTarily recur to the name by which 

 Gmelin originally fet it forth. 



29. FUCUS DENTATUS. 



F. fronde membranacea tenerrima ramosa alternatim pinnati- 

 fida; ramulis linearibus apice incifis, lacinulis acutis. Herb. 

 Linn. Morifon, Hi//. Oxon. iii. f. 15. /. 8. f. 5. bona. 

 Linn. Syjl. FL Ang. p. 582. Fl. Scot. p. 952. Withering, vol. 3, 

 p. 248. 

 Radix callus — Sub ipfo ortu frons ramofa fit — Rami alternatim 

 pinnatifidi, finubuc ramulorum obtufiufculis — Ramuli breves linea- 

 res, nonnunquam etiam pinnatifidi, apicibus femper f. in lacinulas 

 plerumque acutas divifis — Subjlantia membranacea tenera admodum 

 et avenia — Color ruber — Altitudo 2 — 4 uncialis — Fruclificationem non- 

 dum vidimus. 



Obf. Oculo bene armato, ramuli, praefertim ad iinus ramulorum, 

 ciliis breviffimis obfiti videntur. 



We have not admitted the fynonym of Gmelin's corymbiferus, al- 

 though adduced by the authority of Mr. Hudfon and Mr. Light- 

 foot. We have little doubt but that is the F. ciifiatus of Linnseus. 

 It certainly is not dentatus. — That is a large plant, growing a foot 

 high or more : dentatus rarely exceeds five or fix inches. 



We lament extremely our utter inability to fay one word about 

 the fructification. 



Morifon's figure is excellent. There is no danger of confound- 

 ing it with any of its affinities. Teh only one which at all ap- 

 proaches it is the laceratas var. papyraceus ; but the ends of the 

 ^branches in that variety are entire and obtufe — in this divided,
