Discussion English name refers to occurrence in lands of Apache Native Americans. Scientific name commemorates American botanist George Engelmann who discovered the species in 1848. Engelmann named the species Pinus macrophylla, but this name had already been used, species had to be re-named; this was done by the French botanist CarriĖre, who chose to honour Engelmann. Apache Pine sometimes treated as a variety of Ponderosa Pine(as P. ponderosa var. mayriana), now universally regarded as a distinct species.
