How to Search The Plant List

When to use Search

The Search function will locate scientific plant names stored within The Plant List (Scope).

  • You may retrieve either a single species name OR a set of species names which match your search string.
  • You may search using the name of a genus alone OR using a binomial (a genus and species combination).
  • You may search using wild characters in your search strings: using a “?” for any single character and a “*” for any string of characters.

The Search function will NOT retrieve names using search strings including

  • infraspecific names
  • species names with their publishing authors
  • search strings with less than three characters long when using wild characters in your search

The Search function will not retrieve names not within the Scope of The Plant List:

  • Algae or other excluded groups
  • Vernacular or Common names
  • The names of plant families

The Search function will not enable you to obtain statistics about a particular Genus or Family nor see lists of Species names. To achieve these goals please refer to How to Browse The Plant List.

For any particular plant name the Search function therefore enables you to:

  • validate the spelling of that name and to find names that are spelt similarly.
  • find out the currently Accepted (botanically preferred) name for that name.
  • discover all recorded Synonyms of that name.
  • obtain more detailed information about that plant name and the plant for which it is used.

The Plant List was built by bringing together data records from various Checklist Data Sources. This resource was then complemented by the inclusion of any additional names found in IPNI (the International Plant Name Index) (for Angiosperms, Gymnosperms and Fern & Fern Allies) or in the Missouri Botanical Garden’s Tropicos system (e.g. for Mosses & Bryophytes). If you are unable to find a plant name in The Plant List therefore you should first check that you are spelling it correctly. Each of the databases used to build The Plant List will have added plant names in the six months since they passed us their data. These would be included in future versions. We would nevertheless appreciate hearing of plant names that you consider to be missing from The Plant List.

When not to use Search

The Search function will not retrieve names using search strings including

  • infraspecific names
  • species names with their publishing authors
  • search strings with less than three characters long when using wild characters in your search

The Search function will not retrieve names not within the Scope of The Plant List:

  • Algae or other excluded groups
  • Vernacular or Common names
  • The names of plant families

The Search function will not enable you to obtain statistics about a particular Genus or Family nor see lists of Species names. To achieve these goals please refer to How to Browse The Plant List.

Searching The Plant List

The search box can be found on the homepage and at the top right hand corner of other screens.

Submit your search string

Enter a Genus (eg Ocimum) or genus and species (eg Ocimum basilicum).

? will match a single character. * will match any number of characters. Use at least three letters in the genus name if you include a ? or *.

As you type characters into the Search box, you will be prompted with lists of names that match your search string

  • Prompting with generic names as you enter the first word
  • Prompting with binomials once a unique genus name has been entered

If you submit a two word search string that does not retrieve any records then the Search facility will retrieve any names that match the Genus name you submitted

Examples of searches that will work

  • Use Vicia faba to locate this name (and any infraspecific names associated with it).
  • Use Schusterella to locate all names in this genus.
  • Use Quercus a* to locate all names in the genus Quercus that have a species name beginning with the letter ‘a’.
  • Use Psilo* to locate all names in any genera which begin with the letters "Psilo".
  • Use Orchis a????? to locate all names in the genus Orchis which have a species name of exactly six letters, the first of which is the letter ‘a’.
  • Use M?cro* to locate all names in any genera whose names begin with ‘Micro’ or ‘Macro’.

Examples of searches that will not work

  • La* is not a valid search string, since at least three letters are required when a ? or * in the genus.
  • Neither *ubus nor ?ubus are valid search strings since each begins with a wildcard.
  • Using Vicia sativa sativa will return all names that would be found using Vicia sativa rather than just those trinomials matching the full string.

Limitations when Searching The Plant List

The Plant List aims to have complete coverage of the species names for the plant groups included. (Scope)

The Plant List does not aim to have complete coverage of:

  • infraspecific scientific plant names
  • misspelt versions of names used in the literature (spelling variants)
  • records of how a scientific plant name has been misused to refer to a species erroneously (misapplied names)

How to use the Results Page

When one or more names are found that match your search these will be presented on a Results Page.

The number of names which match your search will be given at the top of the screen.

Which genera?

The results page lists each Genus name matching your search criteria providing giving

  • In the case of an accepted genus
  • In the case of a Genus which is not accepted
    • A statement saying that all names recorded in this Genus are Synonyms.

What species information is retrieved?

Each name retrieved will be listed on this screen. Accepted names will appear in bold font. Synonyms and Misapplied names will appear in ordinary font. Unresolved names will appear in a paler font.

Each name record listed will include:

  • the name as included in the source data set
  • any qualifier for that name
  • the status of this name: Accepted; Synonym; Unresolved or Misapplied.
  • the confidence that The Plant List has assigned this status: three stars indicated the highest level of confidence and one star indicating the lowest level of confidence.
  • the source data set from which this name record is derived.

Where the number of name records matching your search criteria is sufficiently high you will be offered a set of initial letters for those species names (epithets) present within each Genus.

Click on any of these letters to jump to names in that Genus beginning with the chosen letter.

Thus in the following example by clicking on the letter “M” you will jump to the name “Welldia macedoi,” which is the first species name beginning with an “M” in the Genus.

In this example Species names in the Genus “Weddellina” begin either with the letter “S” or the letter “U”.

How to sort lists of names

You can sort the list of names that match your Search criteria alphabetically by Scientific Name or alternatively by Status, Confidence level or Data Source.

To sort entries click on the arrow icon on either side of the appropriate column title.

You can sort in ascending or descending order.

How to obtain more information about each name

To find out more about this name simply click on the name in which you are interested.

See Viewing information about each plant.

How to Browse The Plant List

The Plant List contains a separate Browse page for:

  • One page to cover all plants included in The Plant List (the “Main Browse page”)
  • Each Major Plant Group included (“Browse Major Group pages”)
  • Each Family included (“Browse Family pages”)
  • Each Genus included (“Browse Genus pages”)

Each Browse page will provide you with:

  • a list of the plant groups which belong to this node in the taxonomic tree
  • statistics for all plant name records associated with this node in the tree
  • your position within the Plant List taxonomic hierarchy. This will be visible at the top of every Browse page through breadcrumbs placed at the top of each Browse page. Thus for example the following breadcrumb will appear at the top of the Browse Genus page for the Genus Phanerosorus within the Family Matoniaceae within the Ferns and Fern allies Group:

When to use Browse

The Browse function enables you to:

explore the taxonomic hierarchy embedded within The Plant List. You can work down the taxonomic hierarchy from Major Group (to find out which Families belong to each), to Family (to discover which Genera belong to each) or Genus (to see which Species occur in each). From within the taxonomic hierarchy you will be also able to move back up the tree so as to discover, for example, to which Family a particular Genus belongs. The Browse feature will only enable you to detect plant names that are considered to be Accepted (or correct).

  • understand the scope and coverage of the Plant List. You can review the statistics associated with each major taxon.
  • obtain lists of all accepted genera or families included in The Plant List
  • ultimately to select a plant species to find out more about it (see Accepted Name Page)

When not to use Browse

The Browse function will not help you to locate a particular plant name. Use the Search facility to look for a particular plant name. Only accepted names are visible through the Browse function.

How to Browse The Plant List
