Summary

A series of notes on nomenclature and taxonomy, new records and critical taxa for the orchid flora of Equatorial Guinea is presented. Mariarisqueta divina Guinea is lectotypified and isotypes of Angraecum henriquesianum Ridl. and A. quintasii Rolfe are provided. A new subspecies in the genus Eulophia is described. The genera Phaius and Plectrelminthus are first recorded and 20 taxa reported as new for Equatorial Guinea. Habenaria clarencensis Rolfe is synonymised to H. bracteosa Hochst. ex A. Rich. Four taxa are excluded due to misidentifications, one genus and four species need to be confirmed in Equatorial Guinea.

Acknowledgements

We are indebted to the staff of the institutions associated with this study, in particular to Dr Andre Schuiteman, from the Royal Botanic Gardens, Kew, for information on the spirit collection of Solenangis conica. We also wish to thank to Sven Buerki, Joaquim Santos and Matthias Schultz for their search for type materials in the herbaria BM, COI and HBG, respectively. We are grateful to all the curators of the herbaria K, MA and WAG from where we have received very useful loans. This research was supported by the Ministry of Economy and Competitiveness of Spain through the project CGL2012-32934.
