About Pellaea calomelanos (Sw.) Link

It occurs widely across eastern and southern Africa, in the countries Angola, Botswana, Democratic Republic of the Congo, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, South Sudan, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe, where it grows in association with Afromontane vegetation. It can also be found on Madagascar, the Comoros, and the Mascarene Islands. Separated disjunct populations of this fern are located in northern India, Catalonia Spain (specifically at La Cellera de Ter and Sant Llorenç de la Muga), and the Azores. The Kwena and Kgatla peoples prepare milk decoctions from its rhizome to calm children who become frightened at night.
