- NEED IN SITU PHOTOS. The presence of true Southwestern white pine in the Watershed is disputed. Vouchers from both sides of the Valley may be a hybrid of P. flexilis and P. strobiformis. Hogan and Elliot (2022) say that plants on south-facing slopes of the North Sangres of the Watershed have been noted as different and deserve "a closer look" (p. 200). Allred et al. (2020) say that New Mexico shows a "nearly continuous zone of intergradation and introgression," with features merging toward P. strobiformis in the south and toward P. flexilis in the north, and they recognize the intermediate population as P. reflexa (Farjon & Styles, 1997). So what has been called P. strobiformis in the Watershed may be better named P. reflexa or P. flexilis var. reflexa. However named, the tree follows the Rio Grande drainage from Taos and Rio Arriba counties through New Mexico into west Texas. It is a tree found only in Arizona, New Mexico, central and south Colorado, and far west Texas.
