This plant was described in 1910 by Michel Gandoger in the bulletin of the French Botanical Society at species rank. It took over half a century when it was reclassified as a subspecies of Juniperus oxycedrus (Amaral Franco, 1963) and later treated at variety rank under the same species (John Silba, 1984).

Documenting this species requires to hike Vietnam's tallest mountain peak, Fan Si Pan, sometimes spelled as Fansipan or Fan Xi Pan (3143 m), part of the Hoang Lien Son (range). In December 2003, this was made possible with financial help from I.D.R.I. and the guidance of Dr. Dzuong Duc Huyen, country officer of the Prosea (Plant Resources of Southeast Asia) Project, and deputy head of the Botanical Department of the Institute of Ecology and Biological Resources (Hanoi).
Found in 1994 near the town of Yécora, Sonora, Pinus yecorensis turned to be a characteristic hard pine growing (at the type locality) at around 1800 m. Subsequently it was also found 230 km south of Yécora in Chihuahua near the Sonora border, as reported by Rick Fencl.

The tree challenged us for many years: it all goes back to our visits to the Arboretum of Kámon (Kámoni Arborétum) in western Hungary, where there was a large tree named Abies chensiensis var. ernestii...
