Ferns at the extreme: the case of moonworts, grape-ferns and adder’s tongues of the family Ophioglossaceae.

The fern family Ophioglossaceae that comprises the moonworts, grape-ferns and adder’s tongues is an ancient lineage with various strategies in reproduction, speciation, and unique symbioses with fungi. The family is found worldwide and has both temperate and tropical radiations. These ferns occur as both terrestrial plants or epiphytes, and occur in primary forests to disturbed roadsides. There are about 10 genera (notably Botrychium, Botrypus, Ophioglossum, and Sceptridium) and around 112 species some of which are common and widespread, many local endemics and even more poorly understood taxa. There is frequent hybridization and extremely high chromosome number in some groups. The simplified and variable morphology of most species renders species identification and circumscription complicated. This symposium aims to report on recent advances in phylogenetics, taxonomy, systematics, regional floristics, and transcriptome analysis from a panel of local and international experts.
