Abstract

Globba subsect. Nudae K.Larsen is revised. Seven species are recognised and three names are lectotypified. A key to the species and descriptions are provided. Three new species are described and illustrated: G. aranyaniae Sangvir. & M.F.Newman sp. nov., G. lithophila Sangvir. & M.F.Newman sp. nov., and G. macrochila Sangvir. & M.F.Newman sp. nov. Four names based on types from Bangladesh, India and Myanmar remain doubtful. The morphological expression of andromonoecy in this group is described in detail. Provisional IUCN conservation assessments of all species are supplied.
