BOTANICAL SOCIETY OF EDINBURGH. 



This Society held their seventh meeting for the season on the 12th 

 instant, at the Botanic Garden, Professor Christison in the Chair. 

 The following communications were read : — 



1. On Fumaria parviflora, as a native of England. By Mr. C. C. 

 Babington, M.A., F.L.S., &c, Cambridge. — Mr. Babington, in re- 

 ference to an opinion formerly expressed by him, that this species 

 was a very doubtful native of England, not having then seen any 

 specimens agreeing with the true characters of it, now states that 

 he has obtained satisfactory proofs of its being a native, but that 

 most botanists have been in the habit of calling F. Vaillantii by that 

 name. He says, however, that the flowers of English specimens of 

 F. Vaillantii are decidedly smaller than those of some which he pos- 

 sesses from Montpelier, and that in some white-flowered English 

 specimens of the same plant he perceives traces of an apiculus ; also, 

 that in French specimens of F. parviflora the flowers are of the same 

 size as those of F. Vaillantii ; but the fruit has an apiculus. Mr. 

 Babington then proceeds to give a minute description of the princi- 

 pal characters which distinguish this and other allied species of the 

 genus, among which there has hitherto been much confusion. 



2. On the occurrence of Gelidium rostratum, Harv., at Aberdeen. 

 By Mr. George Dickie, Lecturer on Botany, Aberdeen. — This re- 

 markable plant, which Mr. Turner was disposed to consider, though 

 with some hesitation, as merely a variety of Delesseria alata, but 

 which Dr. Arnott and Mrs. Griffiths refer to Gelidium, Mr. Dickie 

 states to be abundant at Aberdeen, though it has not hitherto been
