Abstract
SynopsisThe paper deals with three problem areas in the taxonomy of British willows: (1) the widespread occurrence in Perthshire and neighbouring counties of an intermediate betweenSalix myrsinifoliaSalisb. andS. phylicifoliaL., apparently of hybrid origin, though growing in an area where typicalS. phylicifoliahas yet to be found; (2) the complex taxonomy of the British Sallows, where two common aggregate species,Salix cinerea L. andS. caprea L., are each represented by two segregates; a third,S. aurita L., may also comprise more than one segregate; all three species interbreed, as do the segregates within each aggregate; (3) the disputed identity of the Crack Willow,Salix fragilis L., and its nomenclatural implications.
