234 Dr. GooDENouGH and Mr. \VoodwardV Obfervations on 



been fupplied by feveral of our friends and correfpondents, particu- 

 larly by our worthy and accurate friend the Rev. Hugh Davics, 

 F. L. S. of Aber near Bangor, by whofe aflTiftance we have been 

 enabled to determine it to be our kaiiformis. 



Mr. Hudlon was our chief guide in enumerating the fpecies. 

 But we could not follow him altogether- His having added no 

 defcriptions to his equivocal plants, leaves us extremely in the dark 

 concerning his real determination. Thefe doubts, in confequence 

 of the lofs of his herbarium, cannot now be cleared up. Some 

 fpecies we know are not exifting. His F. fiUformh muft be fuf- 

 pefted to be our comprcfTed variety of crifpus, only of a larger and 

 more robuft foim. His fimbriatus is our fringed variety of membrani- 

 fbl'ius ; \\\^ felaceus is mtvely Jib r of us in a young ftate, in which the 

 leaves are perfe6lly fetaceous ;■ his volubilis is a twifted variety of 

 vejfculofus ; the volubilis of Linnxus is not of Britifh growth : his 

 ■pinnat'ifidus and miiltifidus are one and the fame plant, named only 

 after the thfFerent forms it affumes from the different accidents of 

 its growth and ftation ; his corneus, pltinatus, and flicinus, are alfo 

 varieties only of one individual ; his carlilagineus appears, from his 

 quoting Buddie, evidently to be our corompifolius,. not the tartilagi- 

 ?ieus of Linnasus ; his furce/laius the himbricalis of Gmelin, not the 

 real Linnean plant ; his mufcoides a variety oi aculeatus, with the 

 branches fomewhat round ; and his lanofus is the Conferva polymor- 

 pha. Thefe two laft we have accordingly ftruck out of our lift- 

 entirely. 



With all due deference to Major Velley and Dr. Withering, we 

 have omitted their F. elminthoides and defraSius, the fruflification 

 appearing to us,^from the few fpecimens which we have feen, to 

 be that of the genus Ulva. It is with much diffidence that we 

 diffent from them; we flatter ourfelves that' we are all actuated 



by,
