Where are the fungi/microbes/infraspecifics from Europe?
IPNI aims to include names of all seed plants but the data are not
yet complete. In particular, there are big gaps in Old World infraspecific
names published before 1971. For a list of what is included see About the Index. Since 2004, fern names from the Index
Filicum have been included. For fungi see Index
I can't find some family name records. Is something wrong?
Index Kewensis did not start recording names of families and all
ranks below family until 1971. Up until then only genera and species
were included in the Index.
I searched for a name that should be in the index, but I didn't
find it. What am I doing wrong?
Check our search tips and sample
searches for hints on searching IPNI and also read the page on
understanding the data. If you still can't find
it, let us know.
Can I use the Index to check the correct names for the taxa in
No. IPNI is simply a list of the names which have been published
to date. You can use it to check bibliographic details, and in some
cases type details but the fact that a name is listed in the index
does not mean that it is the currently accepted name for any particular
taxon. For current taxonomic opinion consult an up-to-date flora,
monograph, revision or checklist or ask a specialist.
How can I use IPNI with my database?
Eventually it will be possible to subscribe to copies of the data, or to link your database directly
to IPNI using an API. For now you can use URL
encoding to put links in to individual IPNI records or searches
from your pages or database..
Why does the bibliographic reference often show a range of page numbers?
The reference was recorded like this so that users know exactly which pages of the protologue are relevant to the plant name. The primary page - the page on which the name is published - is always recorded first, followed in parentheses by the pages and figures that hold additional relevant information about the plant.
This method of recording was useful in the past when photocopies of the protologue had to be requested. From May 2012 we began recording only the primary page.
What does an asterisk next to a plant name mean?
An asterisk indicates that the record is awaiting verification by
one of the editors. The record may be a recent addition to the database
or it may be a record that has just been edited in some way. Once
the editors have checked and approved the record the asterisk will
Can I use IPNI to search by common (vernacular) name?
No. IPNI does not include vernacular names of plants as these are
rarely formally published. If you are looking for information about
a plant for which you only have a common name you may find the following
resources useful. (Please note that these links are to external sites
which are not maintained by IPNI)
