It differs from faftigiatus /3 interceplus, in its higher growth and larger 

 fize — in being ufuaily deftitute of geniculations — in its constantly 

 regular dichotomous terminations — in having the extreme branches 

 in the fructifying ft ate, in which, only it could be miftaken, much 

 longer and thicker — and in colour, this being dark reddifh and fome- 

 what pellucid whilfl: frefh, though turning black when dry; in 

 which ftate alfo the fhort oval terminations of .the fajligiat us of the 

 En glim authors contract and become fubulate and acute. The differ- 

 ences between this, plant and trie fqftigiatus of Linnaeus are pointed 

 out under that fpecies. 



It adheres to the rocks and Hones by ftrong fibres, throwing out 

 fhort creepers, which produce other plants, all together frequently 

 forming large maffes, and is found on : /.almoft every part of the 

 Britiih coaft.
