Abstract

A taxonomic revision of Monotagma (Marantaceae) concludes that this genus comprises 37 species, of which the following 18 species are here described as new: M. aurantispathum, M. breviscapum, M. congestum, M. exile, M. flavicomum, M. floribundum, M. grallatum, M. humile, M. lilacinum, M. nutans, M. papillosum, M. paradoxum, M. remotum, M. roseum, M. septentrionale, M. spathulatum, M. tuberosum, and M. uliginosum. Furthermore, the new subspecies M. grallatum subsp. subcentricifolium is described. It is also proposed that these species are best treated in two monophyletic sections, viz. Monotagma sect. Monotagma with 20 species and the new Monotagma sect. Tubularia with 17 species. All new taxa are illustrated and described with notes on distribution and relationships, and a key to all recognized Monotagma species is given.
