Abstract Chamaecytisus proliferus (L.fil.) Link (Fabaceae: Genisteae) represents a species complex in the Canary Islands. Floristic data from 147 releves from the whole complex were collected and analysed by classification (TWINSPAN) and ordination (DECORANA) methods. Results indicate that white escobon of Tenerife, escobon of El Hierro, white escobon of Gran Canaria and typical tagasaste in La Palma are associated with those plant communities from the north of these islands which are under the influence of the north-eastern trade winds. Narrow-leaved escobon in Tenerife and La Gomera, escobon of southern Gran Canaria and white tagasaste of La Palma are found in those areas which are not under the direct influence of these winds. Morphological forms from the more easterly islands (Gran Canaria and Tenerife-La Gomera) have the broadest ecological range and they have played an important role in the floristic changes which have taken place after the destruction of the forests in these islands. The highest priorities for in situ conservation should be given to wild populations of typical tagasaste, white escobon of Tenerife and escobon of El Hierro.
