A-Z Search

You can select from an A-Z list of all plants known to have grown wild in Derbyshire. This is a complete alphabetical listing by scientific name of all species in Derbyshire for the letter you select.

The results will provide a summary list of all the relevant entries, showing the following information:

  • Scientific Name
  • Common Name
  • Latest Year for which records are known
  • A link to open a 2 kilometre distribution map (see distribution maps)

The scientific name will be presented as a hyperlink, allowing you to view maps, species statistics and completed or draft accounts (see species accounts).

Keyword Search

Use the search box to return a list of matches by either scientific or common name. You can type a whole name, or any part of it. Keep your searches short to improve the chances of a correct match.

Tick the check box to widen your search to include words, names or text strings present in the species accounts. Be aware that if you search on "derby", you will get results containing both Derby or Derbyshire. To exclude longer words, make sure you include an appropriate character with your search term, eg "derby " or "derby."

The results will provide a summary list of all the relevant entries, showing the following information:

  • Scientific Name
  • Common Name
  • Latest Year for which records are known
  • A link to open a 2 kilometre distribution map (see distribution maps)

The scientific name will be presented as a hyperlink, allowing you to view maps, species statistics and completed or draft accounts (see species accounts).

Maps and figures are based on data correct at September 2007. The accounts were originally drafted by Dr Alan Willmot in 2003/4 and are now being updated in the light of many new records. Note that because species and subspecies maps and accounts have not yet been merged, some care may be needed when viewing or interpreting entries for certain taxa. Where the letters Xx appear in the species accounts they indicate the start of italicisation of scientific names which will eventually be required in the book form of the Flora of Derbyshire.

You can also return a full county plant list in taxonomic order by using the "View taxonomic list" link.

Distribution maps

example of map image

Maps are available for all species for which grid reference data is available.

  • Large white dots represent old records, collected prior to 1987
  • Smaller black dots represent modern records, collected from 1987 to 2007
  • A solid black dot in a larger white dot (bullseye) represents the presence of a species both before and after the start of 1987.

Two levels of map details are available:

  • Tetrad maps, where each dot represents the presence of one or more records anywhere in an area 2km x 2km in size (known as tetrads)
  • Hectad maps, where each dot represents the presence of one or more records anywhere in an area 10km x 10km in size (known as hectads).

Map backgrounds show a combination of topographical relief and Natural Area boundaries in red. Relief is shown in five colour bands as follows:

yellow Yellow: Under 50m above sea level

green Green: 50-150m

blue Blue: 150m-300m

light purple Light Purple: 300m to 500m

dark purple Dark Purple: over 500m

Species accounts

Jacob’s Ladder (Polemonium caeruleum) at Lathkill Dale SK1665. A national poll recently voted this species as the County Flower of Derbyshire.

Each account gives an overview of the plant, its county status, abundance and occurrence, especially in relation to Natural Areas in Derbyshire. Locations are followed by Ordnance Survey grid references, normally accurate to 1km square. Where locations are given as specific examples they, or their grid references, are presented in round brackets ( ). All other locations are given in non-standard brackets [ ] to indicate they are purely examples of the geographic spread of a species; those chosen have no particular significance above any others.

A statistics box contains information derived from Derby Museum's records database. This includes the earliest and most recent year for which the species is known, plus a total count of the records held. An analysis of grid square coverage for past and modern records is given, based on monads, tetrads and hectads. (i.e. grid squares, that are respectively 1km, 2km and 10kilometre in size). Information on each plant's county status and conservation status is also given. Follow this link for an explanation of the terms used: Glossary.
