an extensive scale I believe many of our difficulties in connexion 
with this group of plants would be solved. — J.G. From the 
original locality, and though the specimen is poor, I believe it is 
correct. — A.B. 
R. trichophyllus Chaix. (1) Pool, near Pagham, Sussex, v.c. 
13, June 4, 1917.— R. J. Burdon. Yes.— J.G. I believe so. 
Leaf-segments unusually long. — E.S.M. (2) Mundham, Sussex, 
v.c. 13, June 4, 1917. — R. J. Burdon. Yes. — J.G. 
R. heterophyllus Weber. (1) Aids worth, Westbourne, Sussex, 
v.c. 13, June 4, 1917. — R. J. Burdon. The long peduncles sug- 
gest a form of R. peltatus, but the specimen is really not sufficiently 
complete for determination. — J.G. (2) Whyke Pit, Chichester, 
Sussex, v.c. 13, June 6, 1917.— R. J. Burdon. I think correct, 
but an unusually small form. — J.G. 
R. peltatus Schrank. (1) Fishbourne, Chichester, Sussex, v.c. 
13, June 9, 1917. — R. J. Burdon. The specimens suggest some 
lax form of R. sphaerospermus, rather than the river state of 
R. peltatus , but I should like to see a series of specimens. — J.G. 
(2) West Hoathley, Sussex, v.c. 13, June 12, 1917. — R. J. 
Burdon. A weak state of R. peltatus with unusually small 
flowers, or a hybrid with that species as a parent. The aquatic 
Ranunculi hybridise freely, and, whenever specimens are met 
with having weak peduncles ascending after flowering and pro- 
ducing few or no carpels, the other members of the group should 
be looked for in the neighbourhood to account for their parent- 
age. — J.G. 
R. peltatus Schrank, var. floribundus (Bab.). In a pond at 
Yate Lower Common, W. Glos., v.c. 34, May 19, 1917. — J. W. 
White. The peltatus- like form with shorter peduucles, which I 
understand by the name. A beautiful specimen, showing what 
can be done by careful floating out, in marked contrast to the 
draggled apologies for specimens one so often has to examine. 
There is no group of plants that better repay care than the 
aquatic Ranunculi. It seems to me that it is worth while in the 
case of these and other water plants to float them out; the 
trouble is not great, especially when one is drying a number, and 
the results are far more satisfactory than if the plants are merely 
spread out as in the case of land plants. — J.G. 
R. sphaerospermus Boiss. Stream at Runcton, Chichester, 
Sussex, v.c. 13, July 3, 1917.— R. J. Burdon. The plant we are 
now calling by this name, and which appears to be a fairly well- 
marked species. — J.G.
