The plant was brought into the garden, and in May of this year 
(1923) has flowered again with flowers of the same abnormal type. It 
has not been found to set any seed, but will be further tested. 
In Penzig’s Pflanzenteratologie (1921) no similar abnormality is 
described for Lychnis dioica, though reference is made to the occur¬ 
rence of " several rings of carpels.. .in various Silenecc ” (Vol. 2, p. 138). 
An interesting floral abnormality of a different kind is also 
described by Buchenau (Ber. d. d. hot. Ges. 21, p. 417 (1903)) for 
a plant of Lychnis dioica , under synonymy of Melandrium rubrum.

THE FORTHCOMING MEETING OF THE 
BRITISH ASSOCIATION, LIVERPOOL, 
SEPTEMBER 12—19, 1923 
A very large number of titles and abstracts of papers intended 
_ for communication at this meeting have been received by the 
organising committee, and it has been no light task to fit as many of 
them as possible into the available time. The work to be communi¬ 
cated ranges over a large part of the vast field of modern botany, 
and, as usual, an effort has been made to keep the papers dealing 
with related topics as far as possible together, so as to avoid the 
constant distraction of the interest of the audience from one subject 
to another, though it has not proved practicable to group all papers 
in this way. 
The President earnestly hopes that all readers of papers will re¬ 
member that they are not addressing an audience exclusively composed 
of specialists fully instructed in the technicalities of their special 
branches of research, and that each author will take pains to be 
thoroughly intelligible to all botanists. It is legitimate for an author 
to assume that his hearers possess a good botanical training and a 
keen interest in the subject as a whole, but it is most undesirable that 
the Sectional meetings of the British Association should cease to be
