THIUSK BOTANICAL EXCHANGE CLUB. 
(curator's report for 1864.) 
By J. G. Baker, Esq., and William Eogoitt, Esq. 
As in previous years, we propose to give a brief notice of the more 
interesting plants that have come before us the past year, restricting 
such notice, as wiU be seen, almost totally to species of which specimens 
have passed through our hands, notable either on the score of cri- 
tical interest, or as having been found in tracts whence they are not 
registered in the ' Cybele Britannica' and its Supplement. 
Thalidnmflexuosum, Bertih-. Mr. A. G. More sends, from the banks 
of Lough Conn, county Mayo, specimens which agree well with this 
plant as found in the north of England. 
Ranunculus paeudo'faUans, Newbould. In the new edition of ' En- 
glish Botany,' Mr. Syme (who places it under R. peltatus along with 
R. Jloribundm, Bab.) savs of this :— " It is a very remarkable plant, 
and may be a distinct subspecies, as the Eev. \V. W. Newbould in- 
clines to think. Professor Babington unites it with R. heteropJiyllus, 
with which it agrees in the weak collapsing leaves ; but in other respects 
it approaches R. peltatus, or rather RJorihundus, and is very possibly 
only a state of that plant, induced by growing in running water. In 
habit it closely resembles R.Jlaitans, but has the segments of the 
leaves shorter, much less rigid, and less parallel, the stamens longer 
than the head of pistils, and the receptacle hispid." Mr. A. G. More 
sends us a supply of specimens from the neighbourhood of Dublin, and 
writes :— " Tlie plant seems as well marked by distinctive characters 
as any other of the British Batrachian Ratiunculi, except fuitans, cir- 
cinatus, tripartilas, Jiederaceus, and cancsus. To the general habit 
and appearance of R.Jluitans, it joins the floating leaves of R. peltatus.
