This study investigates the morphology and distribution of infraspecific taxa of P. subcoronulatum. Research identified taxonomic issues and discrepancies in prior literature concerning morphological similarities among infraspecific taxa. The consolidation of two closely related taxa into a single variety, P. subcoronulatum var. majus, is suggested as a possible solution. This paper presents the first comprehensive morphological description (including dimensions) along with the first-ever images in the form of scanning electron micrographs of P. subcoronulatum var. majus. In addition, a new known geographical location for this taxon in the Okavango Delta, Botswana, expands its known distribution beyond previous records.
