Were not this plant extremely common, and not liable to be 

 confounded with any other, we fhould think it our duty to draw 

 up an elaborate defcription of it in all its various forms. Scarcely 

 a plant in nature varies more : as the extremity of the branches 

 ufually terminates in fomething of a palmated form, the effential 

 character is taken from that circumftance. But it muft be obferved, 

 that it often is very backward in appearing without difguife : often- 

 times the branches are lengthened out without any divihon ; fome- 

 times they are merely dichotomous. Sometimes the frond is proli- 

 ferous, fo as to lay claim to a place in our firft divifion, foliis dif- 

 ihitlis. 



The defcription in the Fl. Scotica perfectly coincides with our 



own obfervations. At Weymouth and elfewhere we have found it 



of a perfectly coriaceous fubftance, as well as the thinned mem- 



3 brane.
