Article Sidebar
Main Article Content
Abstract
Background: Ischaemum is a C4 genus mainly found throughout the tropics of South and Southeast Asia, Malesia, South Africa and South America. Ischaemum roseotomentosum was collected during a vegetation condition assessment in Limpopo, South Africa at the Bonwa Phala Game Lodge in the Waterberg District, approximately 20 km west of Bela-Bela. It constitutes a new record for South Africa.
Objectives: We document here a new record of Ischaemum roseotomentosum found in Limpopo and discuss its taxonomic affinities and distribution based on available specimens, field observations and a review of the relevant literature.
Methods: The collected specimen was morphologically examined at the National Herbarium, Pretoria (PRE), using a light microscope, and compared with type specimens from Zimbabwe in addition to other notable collections from the same area.
Results and conclusion: A specimen of Ischaemum roseotomentosum was collected from a private game lodge in the western region of Bela-Bela and subsequently submitted to the National Herbarium (PRE) for identification. It was confirmed as a new record for South Africa.
