The Plant List and the Evolution of Global Botanical Databases
Accurately cataloging the world's flora is a monumental task that requires global cooperation. For years, The Plant List served as a primary digital encyclopedia for botanical names, aiming to provide a comprehensive record of all known plant species. Launched in December 2010, this initiative was a direct response to Target 1 of the 2002–2010 Global Strategy for Plant Conservation (GSPC), which called for the creation of an online flora of all known plants.
Developed through a partnership between the Royal Botanic Gardens, Kew, and the Missouri Botanical Garden, The Plant List sought to organize the vast and often confusing web of botanical nomenclature—the formal system of naming species.
[ไม่มีภาพประกอบ]Key Facts

- Accepted Species: Approximately 350,699 unique species.
- Global Goal: To halt the loss of plant species worldwide.
From The Plant List to World Flora Online
While The Plant List provided a critical foundation, the need for a living, updated resource led to the creation of World Flora Online (WFO). Launched in October 2012, WFO was conceived by a consortium including the Missouri Botanical Garden, the New York Botanical Garden, the Royal Botanic Garden Edinburgh, and the Royal Botanic Gardens, Kew.
As a project of the United Nations Convention on Biological Diversity, World Flora Online aims to publish a complete online flora of all known plants. This effort aligns with the updated Target 1 of the 2011-2020 GSPC, focusing on biodiversity preservation by providing a definitive taxonomic reference.
Complementary Botanical Tools
The ecosystem of plant databases includes other specialized tools. The International Plant Names Index (IPNI) focuses on providing publication details for plant names without determining which names are the officially accepted species names. Additionally, the World Checklist of Selected Plant Families serves as a database that underlies The Plant List, with new names automatically flowing from IPNI into this checklist.
Analyzing the Findings
The data compiled by The Plant List reveals the complexity of botanical classification. Out of 1,064,035 scientific names, only 350,699 were categorized as accepted species names. These species are distributed across 17,020 genera (groups of related species) and 642 plant families.
A significant portion of the database consists of synonyms—alternative names used for the same species. The Plant List identified 470,624 synonyms, highlighting how frequently a single species has been referred to by multiple names over time. Furthermore, as of 2014, roughly 243,000 names remained "unresolved," meaning botanists had not yet determined if they represented unique species or were simply duplicates.
| Category | Count |
|---|---|
| Total Scientific Names | 1,064,035 |
| Accepted Species Names | 350,699 |
| Synonyms | 470,624 |
| Unresolved Names | 243,000 |
| Plant Genera | 17,020 |
| Plant Families | 642 |
Public Impact and Historical Context
The launch of The Plant List during the 2010 International Year of Biodiversity drew significant media attention. Some outlets, such as Fox News, interpreted the high number of synonyms as a sign of lower biodiversity than previously assumed. However, for the scientific community, the project represented a massive leap in data organization.
The project also built upon the legacy of Charles Darwin, who began the Index Kewensis (IK) in the 1880s. Starting with 400,000 names, Kew has added an average of 6,000 species annually since the IK's inception. While the IK is now integrated into the IPNI rather than The Plant List, it provided the historical groundwork for today's digital floras.
Frequently Asked Questions
What was the primary purpose of The Plant List?
The Plant List was created to be a comprehensive online record of all known plant species names, fulfilling a target of the Global Strategy for Plant Conservation to produce an online flora of all known plants.
Is The Plant List still being updated?
No, The Plant List has been inactive since 2013 (version 1.1) and has been superseded by World Flora Online.
What is the difference between an accepted name and a synonym in botany?
An accepted name is the scientifically recognized name for a species, while a synonym is an alternative name that has been used for that same species in the past or by different researchers.
How does the International Plant Names Index (IPNI) differ from World Flora Online?
IPNI provides details regarding the original publication of plant names but does not make taxonomic judgments on which names are accepted. World Flora Online aims to provide a definitive, accepted flora of all known plants.
Which institutions were involved in creating World Flora Online?
It was developed by a collaborative group including the Missouri Botanical Garden, the New York Botanical Garden, the Royal Botanic Garden Edinburgh, and the Royal Botanic Gardens, Kew.
