Bertiera sinoensis Jongkind (Rubiaceae), a new forest liana from Liberia
Keywords:Bertiera, Africa, tropical forest, conservation
Background: Fieldwork in Liberia in recent years has improved our knowledge of the local endemic species.
Objectives: To describe a new species in Bertiera to accommodate material from the south-east of Liberia that cannot be included in any known species.
Methods: Existing herbarium collections were studied, the new species was studied in the field and the relevant published literature was consulted.
Results: The new species Bertiera sinoensis is described and illustrated here based on six specimens.
Conclusions: The new species adds one more species to the botanical hotspot in south-east Liberia. It is assigned a preliminary conservation status of ‘Endangered’ (IUCN).
