This paper lists 52 taxa of lichens from J. A. D. Jensens Nunatakker in South West Greenland. 30 entries are new to the nunataks. Notes on the distribution of the collected species are given. The age of some large thalli of Rhizocarpon geographicum, R. inarense and Pseudephebe minuscula is roughly estimated. The colonization of lichens on the nunataks is discussed.
