Global Compositae Database

The Compositae is one of the largest plant families in the world. The Global Compositae Database is built on the Global Compositae Checklist which has been moved to the Aphia platform of the  World Register of Marine Species. An international network of taxonomic experts will assess, edit and update the taxonomic information for this important family.

Currently containing 33 061 accepted species

Global Compositae Checklist

Datasets for the Compositae from across the world were integrated in the Global Compositae Checklist between 2006 and 2011 using purpose designed Checklist Integration software (C-INT, Landcare Research, New Zealand). Names were matched using a set of rules and a consensus name was generated with all original data sources linked to that name. The consensus name was a summary of all information from multiple data providers that were in agreement on any given field. Entries were complete to differing levels depending on the data contributed (e.g. only some data sources had type information). Broad distribution data was included, using the TDWG Geographic Standard although, as this is derived from the data contributed, the distribution is not necessarily comprehensive. Taxonomic concepts were also derived from the data sources, using a system of prioritised ranking where local datasets have more weight that global. The most recent version of this Checklist forms the starting point for the Global Compositae Database.
