The article deals with outer characters of a pine from Patsjoki-river, in Finnish Lapland (Pinus silvestris L. var. lapponica (Fr.) Hn.). The tables describe the length of the needles, length of the shoots, branching and inflorescence. The statistical calculations of the data are based on W. Johannsen’s (Elemente der exakten Erblichkeitslehre, Jena 1909) (Elements of exact genetics) methods. The results cannot be generalized because of the insufficient amount of data.
