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

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

 difpofition 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 purplifh co- 

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

 be confounded. 



It varies considerably in length and thicknefs. When unim- 

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

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

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

 Y&RaysSynopfiSy twice at leaft; his n. 53. /.51. being certainly this 

 fpecies in its lengthened, and ?u$o. p. 50. the fame in its fhorter 

 ft ate of growth. 



From comparing our fpecimens with thofe in the Linnsean Her- 

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

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

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

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

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