- Facilitate research into plant function, evolution, and diversity by
providing:
- 1. A central database where currently inaccessible data (e.g.,
inventories) can be deposited, managed, and accessed
- 2. Informatics tools for accessing and linking existing sources of
information on plant distribution, demography, and physiology
- 3. Full searching and downloading of all data in sinlge, standardized
format (e.g., spread sheets, delimited text, xml)

- Different sampling units (individuals, species cover and abundance,
species presence/absence)
- Repeat censuses
- Taxonomic uncertainty (e.g., morphospecies)
- Automatic updating of determinations for vouchered species

- Finds synonyms, lower taxa, and other linked names from existing
taxonomic databases (e.g., Tropicos, IPNI)
- Within regions, interpret names according to synonymized checklists
(e.g., USDA Plants, Flora of Peru, Flora of China)
