l'6o D^. GooDENouGH and Mr. WcodwardV Obfcrvations on 



This fpecies, which does not appear to have been noticed by any 

 author before Hudfon, approaches neareft to young fpecimens of 

 our laccrattis /2. It apppears however to differ in its much more 

 humble growth, and the more tender and dcUcate fubftance of the 

 frond, whicli is perfeiStly entire at the margins, never having that 

 jagged appearance obfervable on the margins of the other. 



The divifions are never palmated, but conftantly dichotomous, 

 often divaricated, and having the dichotomy fometimcs three and 

 even four times repeated, Avheii the frond rifes to two inches 

 or more in height ; although in the Fl. ylng. they are faid to be 

 once or twice only. 



The frudlification, which feems to have been unknown to Mr. 

 Hudfon, is very particular; confifting of fmall tubercles partly im- 

 merfed in the very margin of the frond, whence they projetS fome- 

 what more than half their diameter, always folitary, and confiderably 

 diflant; fo that there are feldom more than three or four on any 

 one frond. The plant is of a pale purplifh red, extremely thin 

 and delicate ; the tubercles dark purple, and when ripe turning 

 almoft black. 



It adheres by fmall fibres to the large maffes and rough flones 

 which form the ftiore at Cromer on the coafl of Norfolk ; and is not 

 unfrequently wafhed up by the tide on the fandy beach at Yar- 

 mouth, and other places to the fouthward. We have met with it 

 alfo at Ilfracombe.
