Acknowledgements
The fieldwork that led to the discovery of Erianthemum nimbaense was conducted during the Baseline Study of an EIA of the Nimba Mts for the Société des Mines de Fer de Guinée (SMFG). I would like to thank the staff of SMFG for their help and assistance in the field. Earlier this year a search for E. nimbaense on the slopes of the Nimba Mts, by Djiba Camara, Nema-soua Loua & Thomas Williams, led to the discovery of several plants of Phragmanthera cegeniana, many thanks to all of them. Also thanks to Jamison Suter from SMFG for taking care of the transport of the new plant samples from Guinea to Belgium. MO is thanked for providing scans from their Loranthaceae specimens from the Nimba Mts and Xander van der Burgt for checking specimens in RBG Kew. And last but not least I want to thank Roger Polhill for reviewing and improving the manuscript.
