Diospyros abyssinica (Hiern) F.White (Ebenaceae), a new distributional record for Rwanda.

Abstract

Background: The native vascular flora of Rwanda is currently the subject of ongoing study aimed at producing a comprehensive and up-to-date national checklist. The discovery of Diospyros abyssinica forms part of the Flora of Akagera National Park project, a focused initiative designed to document and synthesise the vascular plant diversity of this protected area in Rwanda's Eastern Province. The ultimate objective of this project is to generate a complete and authoritative checklist of the Park's vascular plant species, incorporating current taxonomic treatments, verified distributional data and conservation status assessments. The checklist is being developed through the integration of systematic field observations, the assembly and analysis of a comprehensive database of herbarium specimens and a critical review of relevant published and unpublished botanical literature.

New information: A new country-level record of a native vascular plant species previously unrecorded in Rwanda emerged during 2023 fieldwork inventory in the Eastern Province. Diospyros abyssinica is reported as new to the Province, where it is represented in a relict population of only 15 individuals in less than 20 hectares. Due to the species having many uses, it has been prioritised as a species for indigenous tree planting programmes.
