Thalictrum collinum, Wallr. Near Cohvyn Bay, Denbighshire, 
July, 1895. — W. H. Painter, “I should rather have considered this 
a form of T, dunense^ Dum.” — Ar. Bennett. 
T. flavum, L. Wet meadow near Twyford, S. Hants, September, 
1890. — J. Groves. “ I suppose best placed under var. sphcerocarpum, 
though the inflorescence is not characteristic, but according to Boswell 
(E.B. iii.), the characters of the shape of the fruit and panicle do not 
always go together.” — J, Groves. “This also is my experience.” — 
W. H. B. 
Ranunculus trichophyllus^ Chaix. In a field ditch by the banks 
of the Clewydd, near Ruthin, Denbighshire, 30th September, 1895. 
Not recorded for county 50 in ‘Topographical Botany.’ — Charles 
Bailey. “Yes.” — H. and J. Groves, 
R. heterophyllus^ \Veb, ex p., var. triphyllus^ Hiern. Ditch, 
Mitcham Common, Surrey, 23rd May, 1885. — H. Groves. “This 
plant was named triphyllus by Mr. Hiern. We are inclined to doubt 
whether it is the R. triphyllos of Wallroth. It is a well-marked form 
of R. heterophyllus with nearly glabrous carpels and cuneate leaf seg- 
ments, with somewhat hollowed margins.” — H and J. Groves. 
R. floribundus, Bab. Pit near Brassington, Derby, 17th June, 
1895. — -W. R. Linton. “No doubt a small state of R. peltatus^ but 
such miserable scraps are quite useless for distribution.” — H. and J, 
Groves. 
R. peltatus, Schrank, var. floribundus, Bab. Yeldersley, Derby, 
31st May, 1887. — W. R. Linton. “ See observation on the Brassing- 
ton plant. This appears to be an ordinary form of R. peltatus^ but it 
was either collected too early, or care was not taken to select mature 
specimens. It is futile to collect Batrachian Ranunculi at haphazard, 
as in the present state of knowledge of this group it is necessary, for 
satisfactory determination, to have good specimens of well-grown 
plants with at least three or four heads of fruit as well as flowers.” — 
H. and J. Groves. 
R. Ficaria, Linn. Swinley, Berks, June, 1895, in fruit. I thought 
some fruiting specimens, which are said to be rare, might be accept- 
able to some members. In the dry season of 1895, it did not appear 
to be unfrequent in dry situations. These occurred under the shade 
of trees in Swinley Park. They belong to the variety divergens, F. 
Schultz, but some of the specimens are not typical. — G. C. Druce. 
Caltha palustris, Linn., var. This form of Caltha, with narrow 
non-contiguous sepals, occurred in the Cumnor Meadows, in Berk- 
shire, in May, 1895. It may perhaps be referred to the var. 
Gutrangerii. — G. C. Druce. “ I think best placed under var. 
Guerafigerii, but not well marked. Dr. Huth states, in his ‘ Icono- 
graphie der Gattung Caltha^ that after examining many hundreds of
