Taxonomic notes and synonyms listed
This is a very variable species, particularly in West Africa where Hooper and Napper (1972) recognised three varieties. These were the typical variety, var. dichotoma, var. pluristriata (C.B. Clarke) Napper and var. laxa (Vahl) Napper. These subspecies and varieties have been recognised by different authors. Var. pluristriata was given subspecific rank by T. Koyama as Fimbristylis dichotoma subsp. podocarpa (Nees) T. Koyama, while var. laxa is at present on WCSP sunk into the typical species Fimbristylis dichotoma subsp. dichotoma. In some regions of Africa, namely South Africa and the area covered by the Flora Zambesiaca, Fimbristylis dichotoma is not as variable and the nutlets are entirely tuberculate like those of the typical variety as seen in West African countries.

Taxon distribution as listed in assessment
There are literature records for UAE (e.g. specimen by U. Deil in Jongbloed et al. 2003), however no recent records or mentions of this species have been found for the UAE, and its presence needs confirmation. This is also emphasised by the lack of specimens in neighbouring Oman. Globally, this species is known from the tropics and subtropics across the world (Board of Trustees, RBG Kew 2019).
