'rhalictruni flavum^ L., var. nigricans, Jacq. In large masses in 
several spots near Llangorse Lake, Breconshire, 26th July 1906. 
The black coloration of foliage and stem was conspicuous even 
in the fresh plant, and has become more marked when dried. The 
fruits, as usual, are often distorted and swollen by insects, but 
when not so shew the outline of this variety fairly distinctly. Note 
the narrow upper leaves, and the fruits as in Reichenbach, t. 43, 
oval-elliptic, whereas the T. Morisonii has broader, blunter leaves 
and longer fusiform fruits (Rchb. t. 45). — A. Ley. “ This is, 
I believe, the same as a cultivated Welsh plant sent to the Club 
some years ago, which Freyn named T. gallicum, Rouy and 
Foucaud.” — E. S. Marshall. “Yes, Mr. Whitwell grew it from 
a Welsh plant, and I have seen the same form in gardens as well as 
in wild spots in Carnarvonshire. Herr Freyn named it for me 
T . gallicum '' — G. C. Druce. The Rev. E. F. Linton says Mr. 
Ley’s plant is “ certainly not T. gallicum T 
Ranunculus peltatus, Schrank form. R. Rheidol, Llanbadarn 
Fawr, Cardiganshire, June 1906. Mr. J. Groves writes respecting 
these specimens : “Mr. Hiern figured a form with similar leaves to 
these in his paper upon Batrachian Ranunculi, J. of B., 1871, 
Tab. 115.”— W. H. Painter. 
R. Baudotii, Godr. Old river bed, Ashton, near Preston, 
W. Lancs. (60), Septr. 1906. — J. A. Wheldon. 
R. acris, L., var. tomophyllus (Jord.). The Quarries, Wirks- 
worth, Derbyshire, 7 July 1906. The hairiness of this plant 
attracted my attention. — W. Bell. R. tomophylbis (Jord.) I be- 
lieve.” — E. F. L. “ I believe that E. F. Linton is right (i.e. it is 
a hairy form or var. of R. Borceanus, Jord.) ; but I do not know 
these plants very well.” — E. S. M. “ I think correct ; the rhizome 
is sub-vertical, the hairs on the stem patent or deflexed, not 
appressed (as in Borceanus), but the leaves are not so densely 
covered with patent hairs as in typical tomophyllusP — G. Claridge 
Druce. 
R. parviflorus, L. In good quantity on the calcareous cliff, 
and on the sand of the Glamorgan coast : April 1906. N.C.R. — 
H. J. Riddelsdell. “ I have not seen a form quite like this 
before, it has much of the habit of muricatus. The more rounded 
crenations, the distinct rosette of leaves and caulescent condition, 
are characters which separate it from the type, as well as the more 
silky pubescence on the petioles. R. parviflorus is very variable 
in size.” — G. Claridge Druce.
