(l2) THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 1 52 
years. I prepared a series and submitted them to the late Herr 
Maximowicz, and to Dr. Schumann, but they both hesitated to give 
a name. I think it is nearest T. inontanu 7 u, Wallr., var. y glatidu- 
losuffi, Wallr., Sch. Crit. 255, 1822.” — Ar. Bennett. 
T. Kochii, Fr. River-side, Langdale, Westmoreland, July 
1905. Abundant in Great Langdale, from Dungeon Ghyll to 
Skehvith Bridge, Westmoreland : occurring also in Lake Lan- 
cashire. The characters all point to this being the real plant of 
Fries; the fruits, although insect-swollen, shew the ovoid outline 
well. — Augustin Ley. 
Ra^umculus pe/tatus, Schr., var. floribu 7 tdtis, Bab. ? Near Snel- 
ston, Derbs., 23rd June 1905. — W. R. Linton. “A small form 
of peltatnsy but not, we think, R. floribimdus^ Bab.” — H. and J. 
Groves. 
R. Fla 7 )i 77 i 7 ila, L. for 7 )ia. A completely prostrate, but not 
rooting form. Growing on damp spots at Gerrard’s Cross Common, 
Bucks, July 1905. — G. C. Druce. “There is a root on one of the 
specimens, and the beginning of nodal-rooting is evident on two or 
three others.” — Ed. “ In all the specimens seen by me the plant 
tends to be nodal-rooting near the base of the stem. One of the 
innumerable states of the type, in my opinion.” — E. S. Marshall. 
R. Ficaida^ L., var. mcu 7 /ibe 7 is, Schultz. On the margin of 
damp coppice in Ashton Park, North Somerset, 8th April 1905. 
This variety is rather rare about Bristol, and seems to be confined 
to damp, shaded situations, where the plants are luxuriant. The 
amount of fruit produced by the aggregate varies in different 
districts. An examination of about 1,000 plants in the vicinity 
of Bristol shewed that at Westbury-on-Trym only i in 400 was 
fertile: near Long Ashton the proportion was i in 150, and about 
the same at Backwell. I have been told that near Norton Malre- 
ward heads of carpels can be found “in every ditch,”— a frequency 
that might not, however, be greater than that I have last mentioned. 
— Jas. W. White. 
Cal t ha radica 7 is, Forster. At the upper end of Loch Tummel, 
Mid Perth, July 1905. A new county record. Some of the 
specimens were the nearest to Forster’s plant that I have yet seen, 
even the radical leaves being nearly triangular in outline. 1 saw it 
also near Methuen Bog, in the same vice-co. — G. Claridge 
Druce. Also by the Couglass, near Tomintoul, Banff, vice-co. 94, 
15th July 1905. — W. A. Shoolbred. “Leaves more like (in the 
Banff gathering) var. zetla/idica, Beeby, than the original form ; but 
Mr. Beeby would now, I believe, simply call all nodal-rooting
