^{page 254 note *} Since this Memoir was originally presented to the Royal Society, I have had two communications from Professor Dickie on the subject of the name of this plant. In his first (dated 25th March 1859), he says, “Twelve months ago I sent a Borrera, supposed by me to be a variety of Atlantica. I have now good reason to believe that it is new. Should you, therefore, publish anything on British species including it, I should wish it to stand as B. Hibernica, Dickie MSS.” In his second letter (dated 3d June 1859), he remarks, “The supposed P.villora, Dub., has been submitted to Nylander, who pronounces it a monstrosity of P. chrysophthalma. I have compared the fruit in both, and find them identical, so we must bow to the high authority of Nylander.” In giving these criticisms, however, which I do in justice to Professors Dickie and Nylander, I see no reason for in any way modifying or altering my opinion regarding the place in classification or name of the plant in question—as above given.
