again in 1908 — a few shoots bearing normal purple flowers, the 
remainder, flowers of a streaky white and purple — an effect of the 
environment on the same individual which I had noticed before in 
successive generations and wrongly ascribed to crosspollination by 
the Brampton stocks of the neighbouring gardens. — A. H. Trow. 
Nasturtium palustris, Moench., = Radicula palustris. Pumping 
Station, Abbey Lane, Leicester, v.-c. 55, Sept. 1908. Sent with a 
view to determine the form or var. This form is plentiful by the 
side of the River Soar, on the north side of the town. — W. Bell. 
N. palustre, T)C. = R. palustris^ Moench. — G. C. Druce. 
Neslia paniculata, Uesv., by the path of Hollingbury Castle, 
E. Sussex, Oct. 1908. — Alien. — T. Hilton. As I pointed out in 
‘ Flora Berks.’ p. 69, the oldest name for the genus is Vogelia, 
‘Med. Pflanz.’ p. 32, April 1792, and the plant is V. paniculata, 
Horn. See Schinz ‘ Bot. Mus. Univ. Zurich,’ p. 540, 1908. — 
G. C. Druce. 
Rapistrum Linneanum, Boiss. et Reut., var. a glabrum, Cariot. 
On the sand hills south of a new road (Devonshire Road) off North 
Drive, St. Ann’s on Sea, W. Lancs., 9th Aug. 1907. — C. Bailey. 
Lepidium ruderale, Linn. Gloucester Docks, v.-c. 34, 26th Sept. 
1908. — F. L. Foord-Kelcev. 
Reseda stricta, Pers., or inodora, Rchb. ? By the railway, New- 
haven, E. Sussex, June 1908. — Alien. — T. Hilton. 
Helianthemum Chammcistus x polifoHum [ref. No. 3350]. 
Purn Hill, Bleadon, v.-c. 6, N. Somerset, 20 June 1908. Growing 
here and there with the parents, on mountain limestone ; flowers 
pale sulphur-yellow. Mr. L. A. M. Riley had this in cultivation 
two years ago, and told me that it was apparently fertile. — F". S. 
Marshall. This has been referred to x H. sulfureum, Willd. 
I have a similar plant as a “straw-coloured var.” Collected by Miss 
Townsend at Torquay in 1858. — G. C. Druce. 
Viola hirta X sylvestris. Great Doward, Hereford, 15th May 
1908. I feel sure that the plants sent represent this hybrid, which 
I do not find recorded previously. Both parents are abundant in 
the locality. The plants were growing in marshy ground where it 
would be subject to floods. — A. Ley. The outline and texture of 
the leaves, and the narrow petals, favour this view ; likewise the 
sepals. I should have expected, however, to have seen a more 
hooked spur. — E. S. M. I consider this to be a very marked ex- 
ample of V. Riviniana, Reichb., f. villosa. No hybrid between any 
members of the two groups of violets — Caulescentes and Acaules —
