PREFACKH 
HERE is nothing to be said by way of Preface 
to this book except so far as the illustrations 
and the help that I have received from my friends are 
concerned. : 
I have to thank Miss Emily Dust, of Manchester, 
for the Frontispiece, which she was kind enough to 
sketch from a living plant. Turning to the photo- 
graphs, Messrs. Newton & Co., of Covent Garden, 
supplied me with that of the fruits and seeds of the 
Yellow Flag, and Mr. W. Tams, of Cambridge, with 
those of the seed of the Ragged Robin and of the Cut- 
leaved Cranesbill. The shoot and the spent fruit of 
the latter and all the other photographs are the work 
of Messrs. Flatters & Garnett, Ltd., of Manchester. 
With four exceptions the material from which the 
plates and illustrations were taken was supplied by 
myself .I am indebted to the Rev. Henry L. Graham, 
of Eastbourne, for plants of the shingle variety of the 
Herb Robert; the Cluster-cups on the leaf of the 
Barberry were supplied by Messrs. Flatters & Garnett, 
Ltd. ; while the sketch of the single one of the Stinging 
Nettle is the only botanical illustration not taken 
direct from the thing itself. I did not get to this 
point until August, which was too late in the season 
for this species, and I did not think it worth while to 
postpone matters for another year on that account. 
The last exception is the sketch of the beetle Coeliodes, 
which was taken from a Museum specimen.
