Abstract
The World Flora Online (WFO) project (Borsch et al. 2020) was initiated in 2012 in
response to Target 1 of the Global Strategy for Plant Conservation*1, "To create an online
flora of all known plants by 2020" (Wyse Jackson and Kennedy 2009). A WFO Consortium
of over 40 international institutions has been formed. The World Flora Online Public Portal*
2
is built upon a taxonomic backbone of plant taxonomic data that integrates the
International Plant Name Index (IPNI)*3, World Checklist of Vascular Plants (WCVP)* 4,
Tropicos*5, Angiosperm Phylogeny Group 4*6, Pteridophyte Phylogeny Group (PPG I 2016
), supplemented by the Global Compositae Checklist*7, Solanaceae Source*8, and others.
To facilitate the ongoing curation of the WFO backbone, identifiers called WFO-IDs have
been created for each of the over 1.59 million names included in WFO. WFO-IDs are
comprehensive for all known plants, both vascular and non-vascular except algae. IPNIIDs are limited to vascular plants and do not give the current taxonomic status of the name.
WFO-IDs also cover invalid designations, i.e., some effectively published “names” like
orthographic variants that have been used in taxonomic literature, so that their invalid
status is made explicit. WFO IDs follow FAIR principles (Findable, Accessible,
Interoperable, and Reusable). Relationships between WFO-IDs are also recorded by the
WFO Taxonomic Backbone, including synonymy and homonymy, and are accessible via
the WFO Portal. WFO is continuously updating the taxonomic backbone by engagement of

new plant Taxonomic Expert Networks (TENs) focused on selected plant groups. WFO
also includes over 500,000 descriptive data items gathered from digital floras and
monographs, and other sources. Descriptive data can be text descriptions, images,
geographic distributions, identification keys, phylogenetic trees, threat status, lifeform or
habitat. Descriptive data records are all assigned a WFO-ID, if they are new to WFO, by a
name matching process with the WFO Taxonomic Backbone. A new tool called Rhakhis
(Hyam et al. 2022), developed at Royal Botanic Garden, Edinburgh, is used to manage the
WFO Taxonomic Backbone data and includes APIs to access the versioned backbone
data. This presentation will review the origins and history of WFO-IDs and how they are
being used for the World Flora Online.
