Welcome to Eriocaulaceae
Eriocaulaceae are easily distinguished from other Monocot families by their inflorescences in heads (capitula). The family occurs mainly on the tropics, except for Eriocaulon, which is widespread in the five continents. Two diversity centers are recognized, in Southeastern Brazil, especially in the Espinhaço Mountain Range, and in the Guiana Shield, with a high frequency of micro-endemic species. Ten genera, including around 1400 species, are currently accepted, within two subfamilies: Actinocephalus, Comanthera, Lachnocaulon, Leiothrix, Paepalanthus, Rondonanthus, Syngonanthus and Tonina in Paepalanthoideae and Eriocaulon and Mesanthemum in Eriocauloideae. Several species are commercialized in Brazil as everlasting plants, representing an important income for human communities. The micro-endemism, associated with habitat loss and the exploitation of natural populations for trading, threaten several species to extinction.
The classification and nomenclature used in eMonocot - Eriocaulaceae are derived from the World Checklist of Monocots. The taxonomic information was obtained from taxonomic revisions and edited by taxonomist specialists, with permission from the authors and publishers. The aim of this website is to provide a full taxonomic treatment for the family, with descriptions, photos, distribution maps, specimen database and identification keys. However, several taxa are in need of taxonomic revisions and the achievement of this goal relies on future researches that will enhance a comprehensive taxonomy of Eriocaulaceae.
