NOTE ON THE KILKEE FUCUS. 
Though the differences pointed out in our account of this Fucus, 
seemed to be greater than could pertain to a variety of F. distichus, L., 
yet we dared not venture to set aside the opinion of Harvey and Greville, 
who both had referred the Kilkee plant to this species. We have since 
examined the type specimens of F. distichus in the Linnean Herbarium, 
which agree admirably with Dawson Turner’s accurate figure. _ Dr. Har- 
vey has also received specimens from Agardh. He had, as he writes in 
October last (vide Report of Edin. Bot.Soc.), **no authentic specimens of 
the Arctic plant, nor have I seen one, but the specimens exactly agree 
with the descriptions of authors." The authentic specimens from the 
younger Agardh have shown him that, his plant is a distinct and hitherto 
undescribed species, to which he proposes, in a letter to myself, to give 
the name Fucus anceps, Harv, and Ward. Having purposely described 
only the Irish specimens and not mixed up the characters of F. disti- 
clus, L., with those of the Kilkee plant, the diagnosis given in the De- 
cember number of this Journal (p. 353) is only applicable to F. anceps, 
Harv.and Ward. The synonyms, and notice of the geographical distribu- 
tion, must be deleted... We add, from the report already quoted, Professor 
Harvey’s account of the habit of the plant: “It grows in patches on 
little ledges of the perpendicular side of the rock, along with Gigartina 
mammillosa, ete. .. Tt. has quite a. peculiar aspect; when: grow ing. The 
stipes or base of the stem is thick and rigid, and stands erect; while 
the fronds are just sufficiently limber to. bend over but. not to lie flat, 
so that the Mi looks like a miniature grove of 6 P die Willows." ....
