132 Dr. GooDENOUGH and Mr, Woodward'j Ohjervatiom on 



tigua fubimbricata, per extremos ramulos confica, bafi foliorutn vix 

 majora — ^w^^xZ/rtcartilaginca— Co/or recentis olivaceus, ficcata; niger. 



F. granulatus, ericoides, and JeLiginoides, approach fo near to each 

 other, that it requires the utmoft attention to keep them feparate. 

 — Ericoides is of low flaturc, ere£l hke a httle fhruh, and very bufhy ; 

 and the tubercles are cluftered at the ends of the ramuli lik^ grapes. 

 — Granulaiin and Jelaginoides are of tall and more infirm growth. 

 Of thele, Jelaginoides has its tubercles folitary, and fomewhat diftant, 

 at the bafe of the leaves of the extreme branches ; but granulatm 

 has them contiguous, and fet clofe all along the extreme branches, 

 and even part of the greater branches. The leaves in all are 

 fubulate and acute, but vary in proportion to the fize of the tu- 

 bercle. — \\\ Jelaginoides they are four times larger, in ericoides twice as 

 large, and in granulatus not much larger. We have never feen it in 

 a growing ftate, but have found it along with ericoides and felagi- 

 noides wafhed on the {hore at North Yarmouth. 



The leaves in all thefe fpecies are very liable to fall off; in this 

 ftate the frudtification affords clear marks of diftin£tion. ¥. bar- 

 batus alfo comes very near to ericoides when thus mutilated ; but 

 the branches are ufually dichotomous and always entire, whereas 

 in ericoides they are very ramofe, and bent in fomewhat an angular 

 or zigzag dire6lion.
