Systematics, natural history, and conservation of Erica (Ericaceae).

Worldwide, many tens of thousands of plant species are threatened with extinction in the wild. Those that are naturally rare or have narrow distributions are particularly vulnerable. The flowering plant genus is a prime example, its numerous species presenting additional challenges associated with conserving large, complex, plant groups. This topical collection of papers represents a substantial body of research on inter-dependent themes in nomenclature, taxonomy, phylogeny, ecology, and conservation of species. It will serve as a lasting resource and reference, helping us to better understand, describe, and name species diversity and improving our knowledge of the complexity of ecological interactions in the wild. These advances will aid and champion conservation of natural habitats and support targeted efforts to secure the most critically endangered species in seed banks and botanic gardens.
