Epilohium Kirmtum, L. x E. parviflorum Schreb. 65, N.W. York; 
margin of pond, Sutton Howgrave, Sept. 9th, 1947. Growing with both 
parents. — C. M. Rob (Ref. No. 4742). 
Epilohium rosenm Schreb. 35, Mon. ; in cultivated garden, Staun- 
ton Road, Aug. 10th, 1947.— R. Lewis (Ref. No. 1404). “ Yes, I agree.”

Epilohhim ohscurum Schreb. 35, Mon.; in cultivated garden, Staun- 
ton Road. — R. Lewis, det. G. M. Ash (Ref. No. 1403). 
Bidens cermta L. var. radiata DC. 70, Cumberland; Moorhous« 
Tarn near Wigton, Aug. 24th, 1947.— Miss C. W. Muirhead, comm. 
Carlisle Museum. ” Beautifid specimens of an uncommon and in- 
teresting variant which Linnaeus described as a species — Coreopsis 
Bidens (1753, Sp. pi., 908). The earliest name as a variety of B. cern/ua 
would apj)ear to be var. radiata Roth (1788, Tentamen, 1, 351), of 
which var. radiata Wimm. & Grab. (1829, El. ‘Silesiae, 2, 117), and 
rar. ligvlata Bonnet (1883, Pet. FI. Paris, 211) are later synonyms. 
I .should prefer to call it forma radiata (Roth) Larsson (1859, FI. Werm- 
land, 220).” — J. E. Lousley. 
Bidens frondosa L., rayed form. 41, Glam.; canal bank, Cardiff, 
Aug. 27th, 1947.— A. E. Wade, comm. National Museum of Wales. 
” A native of America (mainly in the eastern States from New Bruns- 
wick to the Gulf of Mexico), this species seems likely to become as well 
established in England as it is in several other European countries. It 
was first observed in north Germany in 1896 and is now found by a 
number of rivers draining into the North Sea and the Baltic and it 
extends into Poland. Tn Holland it was first noticed near Nijmegen in 
1926 and from 1932 it spread rapidly along the Maas as is well shown 
on the map showing its distribution in 1939 in Ned. KruidJc. Arch., 49, 
308 (1939). Tt is also recorded for Belgium, Portugal and Italy. In 
1925, Wade and Smith (1926, B.E.C. 192.5 Bep., 1015) recorded it as 
“ thoroughly naturalised and rapidly spreading ” at Cardiff, but in 
1938 (1939, B.E.C. 19-3H Bep., 79) it was “ decreasing at Cardiff Docks 
and will probably die out.” From the fact that it has persisted so 
long, and judging from its behaviour on the continent, it is more likely 
to extend its ground. Hegi (1918, III. FI. Mittel-Eur., 6 (1), 519), 
Dutch authors, and others, have used the name B. melonocarpus Wie- 
gand (1899, Bull. Torr. Bot. Club, 26, 405), but Sheriff (1937, The 
Cenns Bidens, 241), has summarised and amplified Greene’s work show- 
ing that Wiegand was in error and his name superfluous. In addi- 
tion to Glamorgan, the plant has been collected from various places 
near Bristol, and from Dagenham, S. Essex — specimens in Herb. Kew. 
Rayed florets are liable to occur in a number of species of Bidens and 
generally have no taxonomic significance. The specimens of the gather- 
ing T received are not the var, anomala Porter ex Fernald.” — J. E. 
Lousley.
