202 Dr. Go ode xoug it and Mr, Woodward'j Obfervatlons on 



extraordinary exertion, and of courfe there is not flrength to repeat 

 it often. We apprehend that this is the cafe with our prefent 

 plant : having received an injury, it is capable of making a feeble 

 effort to reftore itfelf, and after that fubmits to its fate. 



We have thus defcribed faithfully what we have feen. If any- 

 one fhould doubt our folution of the phenomenon of the rings, 

 perhaps if he refides for any length of time on the fea-fide, and will 

 take the trouble of marking any particular plant, and will cut, or 

 rather break off, the extremities of the branches, poflibly he may 

 fee the reparation made in the manner which we have mentioned. 



It differs from lumbricalis by the wide, opening of the ramifications 

 of the branches approaching almoft to a right angle ; and from, 

 that and radlatus by the fhortnefs and bluntnefs of the branches. 

 Lumbricalis has thefe rings occafionally, but,being of a firmer texture, 

 is more feldom broken off, and of courfe bears fewer marks of re- 

 paration. 



Specimen's whereon the rings are to be feen, remain in Uvedalis 

 Herbarium,/. 9. n. 4. and in the Collection by Buddie and Vernon*
