Last summer the Librarian of the Soc. Royale de Botanique 
de Belgique expressed a desire to exchange publications with us. 
This was gladly assented to, and as many of our back Reports as 
could be spared were sent to Brussels in exchange for several 
numbers of the Bulletin. The Bulletins are being housed and 
placed on loan in the Dept, of Botany at the University of Bristol, 
and can be borrowed by application to Prof. O. V. Darbishire 
and payment of postage, or by writing to the Secretary of 
W.B.E.C. 
Thalictrum minus L. Devil’s Dyke, near Beechamwell Warren, 
W. Norfolk, v.c. 28, Oct. 9, 1924. This is perhaps var. collinum . — 
J. E. Little. This is the same form as was collected at Tottington 
(B.E.C. 1914 Rep., p. Ill) as T. minus var. montanum, and from 
Cocklejr Cley (W.E.O. 1917 — 8 Rep, p. 48) as T. minus var. 
collinum. The latter name is certainly incorrect, while the former 
is a name whose significance is doubtful. The plant is small to 
medium in size, without definite “leafy base ” ( i.e . leaves crowded 
together owing to shortening of the internodes), the leaf glands 
(underside) few (below) to moderate (above), but difficult to see 
as the foliage is not dark green like the Snowdon form but dries 
a light colour, the fruit probably moderately long, but I have 
seen none ripe. It may be a less glandular form of the (general^ 
“ leafy-based ”) plant which occurs on Newmarket Heath, Cheddar 
(one of the two forms), Derbyshire dales, Gfreat Orme’s Head, 
Gordale and Malham (Yorks), and Kyloe Crags (Northumber- 
land), etc., and which 1 suspect may be T. monticolum Jord. 
• But definite names must await observation of habit and fruit. — 
A. J. Wilmott. 
T. minus L. (1) Rocky ledges, Clogwyn, Snowdon, August 
31, 1924. — D. G. Catcheside. (2) Clogwyn du’r Arddu, Snowdon, 
September 1, 1924. — J. L. O’Loughlin. It is impossible with our 
present knowledge to give definite names to the British forms of 
the series Minores. This form I have only certainly seen from 
N. Wales. It has previously been called T. collinum Wallr. by 
E. S. Marshal], but it is not that because its fruits are elliptic 
and not shortly ovoid. It is practically without glands on the 
leaves, and this character taken with the fruit shape brings it 
under the forms properly placed under T. Jacquinianum Koch, 
although it is not the typical form. The whole group requires 
revision, and before that can be done more field work and 
critical collecting is necessary. It is necessary to have the 
completely ripe fruit, collected in October or later, since the
