Thalictru 7 n collinum, Wallr., fide A. Bennett. Rocks near Black- 
head, Co. Clare, 12th July, 1894. Leg. P. B. O’Kelly. In the report 
of the Watson Exchange Club for 1893-94, Mr. Bennett pronounces 
this plant (of which I had sent specimens for distribution under the 
name of T. inajus or T. flexuosum ) to be T. collinum^ Wallr. = 
Jacqutniamwi, Koch, and not T. 7 najus^ Crantz. On referring to 
Mr. Egerton Warburton’s little handbook of ‘Synonyms of British 
Plants,’ I find it there stated (p. 157) that 71 colIi 7 iu 77 i, Wallr. = 71 
saxatiky DC., but as my specimens of the latter, from the Gogmagog 
hills, do not agree with the Clare and Arran plants, I again referred 
the matter to Mr. Bennett, who, while remarking that it is difficult to 
say what the Gogmagog plant really is, states that he is quite satisfied 
that the Clare and Arran plants are neither 71 saxatile of Schleicher and 
Decandolle. In this uncertainty I venture to send a batch to this 
Club in the hope that further investigation may tend to throw some 
light on the subject of the identity of this Thaliciru 77 i. It will be 
observed that the specimens differ among themselves considerably, 
especially as regards the cutting and size of the leaves. — H. C. Levinge. 
“ This plant from Blackhead, Co. Clare, is, I think, rightly named 
71 collinu 77 i^ Wallr. The confusion in this group of the genus arises 
from there being too many names for one or two forms. This species 
in particular has been variously named 71 77 itnus, Linn., 71 Jacqum- 
ia 7 iu 7 /i, Koch, 71 Jiexuosu 77 i, (Bernh.) Rchb., 71 saxatile^ Bab., and 
71 77 ii 7 ius, Linn., var. 77 io 7 itanu 77 iy Syme, and I suspect that 71 7 /iajtiS, 
auct. Brit, may be added to the number of synonyms. 71 77 imuSy 
Linn., would seem to be quite indefinite. 71 saxatile, DC., is not 
known for Britain ; the Cambridgeshire plant was so called in 
error.” — E. F. Linton. 
Ranunculus . Pond at Milford, Surrey, v.-c. 17, 7th May, 
1894. R. trichophyllus, ioxm2i. This plant has the receptacle 
oblong, not round, as described for R. trichophyllus, of which however 
I think it to be a form. — E. S. Marshall. “7?. tricJiophyllus, Chaix,
