form alters when the fruit ripens. It is also necessary to note 
the rootstock and mode of growth ; some, as this Snowdon form, 
is what has been described as “ caespitoso,” i.e. a single shoot is 
sent up from the same stock for several years, so that the plant 
is not “extensively creeping” as are so many of the forms. It 
is therefore necessary to collect the root-system thoroughly. 
Sometimes two forms majr occur together, as at Cheddar, and 
this has caused confusion. The covering of fine glands should 
be carefully observed ; the lowest leaf is either eglandular or 
with many fewer glands than the middle leaves, and the upper- 
most bractiform leaves are normally the most densely glandular, 
and may bear some glands when the rest of the foliage is without 
any. When this is recognised, I think it may be found that the 
glandular covering affords good characters which are correlated 
with the fruit shape : in collecting the ripe fruits, fragments of 
the main leaves (even if withered) should be collected with them 
and the fruits of the different individuals kept separate, if two 
forms are suspected to occur together. I should be glad to receive 
series of specimens collected in flower, in fruit, and ripe fruits, 
with notes on the habitat and mode of growth, with a view to a 
more satisfactory account of this difficult group.- — A. J. Wilmott. 
Ranunctilus circinatus Sibth. In the moat at Kew, Surrey, 
v.c. 17, June 7, 1924. — D. G. Catcheside. I do not think this 
calls for any comment. The species is, I think, always quite 
distinct from any other. — J. G. 
R. irichophyllus Chaix (and ? /. radians or/. Godroni. Growing 
with R. trichophyllus). Floating leaves ± circular, with three 
main divisions, each with rounded lobes ; the sinus between the 
two main lateral lobes deep, V-shaped ; the sinuses on either side 
the smaller mid-main lobe reaching half way, V-shaped. Stem, 
petioles and underside of floating leaves hairy. Receptacle 
globular. Peduncles about equalling petioles. Petals up to 
9mm. long and 6mm. wide, ± contiguous. Carpels hairy Pond, 
S.W. of Park Wood, near Marden Abbey, Beds., v.c. 30, May 13, 
June 14, 1924. The later gathering is not good material, but it 
was the best that I could get. — J. E. Little. The specimens 
collected in May seem to be good trichophyllus. Those in June, 
from the many weak peduncles and undeveloped carpels, as well 
as the general appearance, I should have thought a hybrid, 
possibly R. pcltatus x trichophyllus. One would like to know if 
they came from precisely the same spot as the May specimens, 
and whether either of the floating-leaved species were present in 
the neighbourhood. Hybridity with these plants, which is very
