Corsia
''Corsia'' is a little-studied plant genus from the monocotyledon family Corsiaceae. It was first described in 1877 by Italian naturalist Odoardo Beccari and contains 25 species, all of which lack chlorophyll and parasitize fungi for nutrition. All 25 species are distributed through New Guinea, the Bismarck Archipelago, the Solomon Islands and Queensland, Australia. ==Description== In terms of appearance, the species of ''Corsia'' are quite uniform except for the flowers.〔Paul Kores, David A. White, Leonard B. Thien: ''Chromosomes of Corsia (Corsiaceae)'', American Journal of Botany, Vol. 65, No. 5 (May - Jun., 1978), Page. 584-585, 〕 Chromosome counts are known only from two species: ''Corsia cornuta'' and ''C. clypeata''. Both have a diploid number (''2n'') of 18.〔〔
