Habitat in rupibus et faxis fub-marinis apiid Cromer in 

 Norfolciii — Haflings SuflTexia, et in Infula Portlanciia?.. 

 Radix fibrofa— F/'ow cartilaginea, filiformis, teres, variat pro fitu 

 dodrantalis, etiam bipedalis ; nunc fili emporetici minoris, nunc 

 fctas equinae crafllticm asquans — Statim a radice fit ramola, ra- 

 mis fetaceis, vel fimplicibus vel ramulis paucis fub-diftichis in- 

 ftrudis — Fru£tificatio, tubercula femi-globofa crebra, magnitudine 

 feminis finapis ad latera ramorum ramulorumque fpajfa — Color re- 

 centis plantas purpurafcens, ficcataj nigrefcens.. 



This fpecies differs from albidus by being longer, by its branches 

 being much fewer, and not attenuated towards the bafe — by the 

 diipofition of its ramuli being diftichous, and not on one fide only 

 of the branches — by having much more numerous and fmaller 

 tubercles, and thefe always femi-globofe — and by its purplifli co- 

 lour. With the other fpecies in this divifion it cannot poflibly 

 be confounded. 



It varies confiderably in length and thicknefs. When unim- 

 peded in its growth, it is flender, long, and. very little branched. 

 Where it is more confined, it is thicker, fliorter, and throws out 

 more branches ; which has occafioned it to be defcribed by Dillenius,, 

 in Rays Synopjis, twice at leaft; his n. 53. p. 51. being certainly this 

 fpecies in its lengthened, and /7.50. /. 50. the fame in its fhorter 

 ftate of growth. 



From comparing our fpecimens vi^ith thofe in the Linnsean Her- 

 barium, it appears that both this plant, and our next, the albidus 

 of Hudfon, were confidered by Linnseus as one and the fame plant, 

 for they are both ftyled by him F. confervoides. It is not therefore: 

 to be wondered at, that Linnseus refers to verrucofus Gmel.for a., 

 figure of his confervoides^ which figure of Gmelin, from his defcrip-.
