IN TROD UCTION 
a special study. An endeavour will be made to render these accounts as uniform as possible, 
in general treatment, with the rest of the work. In the present volume, the Rev. E. S. Marshall 
( Betula ), Dr E. J. Salisbury (, Salicornia ), Mr C. E. Salmon (Salsola), and Mr A. J. Wilmott 
(A triplex) have rendered assistance in this way. We have also to thank the Rev. E. F. Linton 
and Mr C. E. Salmon for kindly supplying us with notes on Polygonum, Rumex, and Chenopodium. 
Specimens for drawing 
We also wish to thank most heartily all who have sent specimens of plants to Mr Hunnybun 
for his 'drawings. When such specimens have been utilised, the initials of the sender and the 
county from which the specimen was sent are, wherever this is possible, stated in the text, after 
the explanation of the plates. The following are the names of botanists who have kindly sent 
specimens which have been utilised by Mr Hunnybun for reproduction in the present volume : — 
Mr R. S. Adamson, the late Mr W. H. Beeby, Mr S. H. Bickham, Mr F. H. Davey, 
Mr G. C. Druce, the late Mr A. Fryer, Mr J. Groves, Mr S. Guiton, Mr D. A. Haggart, 
Mr A. Hallard, Mr F. J. Hanbury, Professor A. Henry, the late -Mr T. Hilton, Mr A. Holland. 
Mr E. M. Holmes, Miss Mildred Hunnybun, Miss C. E. Larter, the late Rev. A. Ley, the 
Rev. E. F. Linton, the Rev. E. S. Marshall, the late Mr J. Needham, Mr C. E. Salmon, Mr C. C. 
Vigurs, and Mr A. Wilson. Without the free and hearty co-operation of botanists in sending 
specimens to Mr Hunnybun, the production of the present work would be impossible. 
In certain cases, Mr Hunnybun has had to rely for specimens on plants grown in botanical 
gardens ; and the Director of the Royal Gardens at Kew (Sir David Prain), the Curator of 
the Royal Botanic Gardens at Edinburgh (Professor I. Bayley Balfour), the Curator of the 
Royal Botanic Garden at Dublin (Sir F. W. Moore), and the Curator of the University Botanic 
Gardens at Cambridge (Mr R. I. Lynch) are thanked for their kindness in forwarding specimens. 
In a large number of cases, Mr Hunnybun has gathered the specimens himself; but, as 
this, as a rule, is no longer possible, we venture to hope that specimens will be supplied to him 
even more freely than before. 
The Illustrations 
All Mr Hunnybun’s drawings are made from living plants. It is thus hoped that many 
errors will be eliminated. For example, we believe that some of the open flowers of published 
illustrations, particularly in such genera as Cerastium , Sagina, and Arenaria, never had an 
objective existence ; but every open flower drawn by Mr Hunnybun is an image of an actual 
object. The main figure on each plate is drawn natural size ; and when enlargements are 
figured, attention is drawn to the fact in the text. All the drawings are reproduced by photography. 
Botanical terms 
In another volume of the work, a glossary of terms will be provided. In the meantime, 
we can only refer readers to Willis’s Flowering Plants and Ferns and Jackson’s Glossary of 
Botanic Terms , where most of the technical terms used in the present work will be found to 
be explained. It is scarcely necessary to state that the glossaries in existing British floras are, 
from the standpoint of modern botany, unsatisfactory. 
Systematic arrangement 
The arrangement of the plant-groups in this work follows, in general, that of Engler and 
Prantl, the eminent German systematists, as seen in the volumes entitled Die natiirlichen Pflanzen- 
familien and as summarised in Engler’s Syllabus der Pflanzenfamilien (editions i — 7 ; ed. 7, by 
Engler and Gilg). No British flora based on this arrangement has appeared before; and the 
only local flora in English which adopts Engler’s plan is Lester-Garland’s A Flora of the Island of 
fersey (1903). We take the present opportunity therefore of stating that British botanists will find 
a synopsis of Engler’s system, so far as genera and groups of higher than generic rank are 
concerned, in Carter’s Genera of British Plants.
