226 Dr. GooDENOUGii ond Mr. Woodward'^ Ohfcrvatiom on 



proccfs, as may be eafily ieen in the gelatinous variety, which is 

 ufiially of a pale colour, and has a confidcrable degree of tranfpa- 

 rcncy. 



The fubftance of the plant, though cartilagineous, is tender, 

 and in fome fpecimcns very much approaching to gelatinous. The 

 principal ftem is continued throughout, and is generally naked for 

 a fmall fpace at the bafe, after which it is thickly clothed with 

 branches, of which thofe below the middle -are longeft, and the 

 upper very fliort, giving a lanceolate outline to the whole frond. 

 The primary branches are fometimes oppofite and fometimes alter- 

 nate, but much more frequently grow without order — thefc are 

 again once or twice branched, and the terminal ones are not unfre- 

 quently crowded. The colour is fometimes wholly purple, but more 

 frequently a mixture of dirty white, green, and purple ; and the 

 more the plant approaches to being gelatinous, the lefs purple is 

 to be obferved in it. 



That this is the fpecies defcribed in R. Syn. p. 50. «. 51. under 

 the name of ' Fucus teres albus tenuijjime dlvifus,^ no one who reads 

 the defcription there given can doubt, (' crebris fccpe nodulis donatur, 

 ' qua non ad latus harent^fed ab ipfts caiiUcuUs tranfad'tguntur''') though 

 Mr. Hudfon has unaccountably referred this fynonym to his albi- 

 dus, the frudlification of which he defcribes as lateral. Gmelin, 

 following the firft edition of Flora ylnglica, has given this fynonym 

 of Ray to his albus, in which he has fallen into a double error ; for 

 not only the fynonym really belonged to h\s purpureus, the pwpureus 

 of Hudfon's firft edition, and purpurafcens of the fecond, but alfo the 

 albus of Fl. Ang. ed. i. the albidus of the fecond edition, ought not 

 to have been referred by Gmelirf to his albus, but to his verrucojus, as 

 Mr. Hudfon has rightly done in his fecond edition. There can be 

 no doubt but ihe purpureus of Gmehn belongs to this fpecies, though
