The Pinus mugo complex is revised, and a new infraspecific classification of the species is proposed. The species is divided into two subspecies and an intermediate nothossp., viz. ssp. mugo, ssp. uncinata and nothossp. rotundata. P. mugo ssp. mugo is divided into f. mugo and f. applanata comb, et stat. nov. (P. pumilio) and P. mugo nothossp. rotundata into f. rotundata and f, mughioides comb. nov. The putative hybrid P. mugo × sylvestris found in mixed stands of the parents is named P. × rhaetica. A description of P. sylvestris and a key to P. mugo, P. sylvestris and P. × rhaetica is given.
