PREFACE. 
HE project of producing a Flora of Derbyshire announced in 
the Journal of Botany in 1896, 46, is so far accomplished 
that it seems desirable at length to publish results, though, no 
doubt, further investigation will yield many more data of interest. 
The present work, accordingly, cannot be regarded as much more 
than a stage forward towards a complete account of the botany of 
the County. It is to be regretted that some departments, as 
Fungi, Lichens and Algz, owing to the lack of time and workers 
to investigate them, have had to be omitted from the present 
volume. During the ten years which have elapsed since the 
work was first entered upon, nearly every parish has been visited 
and searched, either by the author or by helpers co-operating 
with him. In the Flora the older records have, as a rule, been 
inserted, and are commonly placed after the later and more 
recent notices, thus, together with the mention of the first records, 
giving a historical aspect to the account of the County botany. 
It will be remarked that many entries of previous publications 
have been altered, and some omitted; in most cases this is 
because they have been found to be erroneous, e.g., Mr. Water- 
fall repudiated many of the records attributed to him in C.D., 
and supplied a fresh list, which supersedes his earlier contribu- 
tion. All the authorities employed in C.D. have been carefully 
gone through, and corrections made where necessary, among them
