Notes on the endemic plant species of the ebo forest, cameroon, and the new, critically endangered, palisota ebo (Commelinaceae)

Abstract

Background and aims – This paper reports a further discovery in the context of a long-term botanical survey in the Cross River-Sanaga interval of west-central Africa, focussing on species discovery and conservation. Methods – Normal practices of herbarium taxonomy have been applied to study the material collected. The relevant collecting data are stored in the Herbarium of the Royal Botanic Gardens, Kew, London. Key results – The growing number of endemic species being discovered from the Ebo forest of Cameroon points to the importance of its conservation. Palisota ebo Cheek (Commelinaceae) is described as an additional new species to science and is compared with P. flagelliflora Faden. Restricted so far to the Ebo Forest its conservation status is assessed as Critically Endangered (CR B1+2ab(iii)) according to the 2012 criteria of IUCN.
