Chromosome Numbers of Angiosperms from the Juan Fernandez Islands, the Tristan da Cunha Archipelago, and from Mainland Chile

Chromosome counts for eight native species in six genera from Juan Fernandez Islands, five native species in three genera from Tristan da Cunha, and three species in two genera from mainland Chile are presented and discussed. They include the only chromosome number reports for angiosperms from Tristan da Cunha and first counts for the endemics Robinsonia thurifera and Wahlenbergia larrainii ( Juan Fernandez), Agrostis carmichaelii, Acaena sarmentosa, A. stangii, and Nertera holmboei (Tristan da Cunha), and for Galium araucanum and Ourisia coccinea from Chile. Counts for Eryngium bupleuroides and Galium hypocarpium differ from earlier published reports.
