The var. chiapensis was described by Martínez (1940) for disjunct populations from southern Mexico and Guatemala with slightly finer needles and slightly larger cones. Some botanists continue to maintain this as a separate variety (Farjon et al., 1997), but many others do not consider these differences discrete enough to warrant formal taxonomic recognition. Pinus monticola of the western United States also was treated as a variety of P. strobus by a few botanists in the past (P. strobus var. monticola (Douglas ex D. Don) Nutt.), but this view has been rejected universally.
