126 The Flora of Wiltshire. 
lists are numerous, yet he is still desirous of receiving further ad- 
ditions, more especially for the neighbourhood of Marlborough, as 
yet but little investigated by botanists generally. 
Such then are the districts into which it is proposed to divide 
Wiltshire, for the better study of its “Flora;” and as previously . 
mentioned, the species will be severally traced through each divi- 
sion and district, so far as ascertained to occur in them. With a 
tabular summary of the. numerical results, we gain an amount of 
positive information, and a probable test of negative information, 
such as we should be unable to extract from any other local 
Flora written in the ordinary method. Again, when this series of 
papers is brought to a conclusion, they will comprehend five 
several Floras, which will be more or less complete catalogues of 
species for as many different sections of the county. Also two 
distinct Floras for larger tracts formed from the union of minor 
sections. The author will then be better prepared to enter some- 
what more fully, than he otherwise could have done, into the 
causes which govern the distribution of the various species of 
plants throughout the county generally.! 
1 For the sake of uniformity with the ‘‘ Cybele Britannica,” (the catalogue of 
British plants, published by the Botanical Society of London,) the fifth edition 
of which has just made its appearance, has been used as an index of nomencla- 
ture and arrangement.
