Until recently, the taxonomic classification of Little and Crutchfield (1969) was still widely used, which involved subdivision of the genus into three subgenera and a complex series of sections and subsections. Subsequent studies, including analysis of molecular data resulted in the recognition of only two subgenera (Price et al., 2003), the so-called Soft or Haploxylon, Pines (subgenus Strobus) and the so-called Hard or Diploxylon Pines (subgenus Pinus), each of which still is divided into a complex series of sections and subsections. In either classification, P. strobus is the type of Pinus subgenus Strobus section Strobus subsection Strobi.
