Comments
Of this broomrape there are three Watershed collections, all in the same vicinity of Saguache Co: the Great Sand Dunes (1947 and 1965, Harrington coll) and Baca National Wildlife Refuge (2006, Regensberg coll, Turner Collins det). Note that these SEINet herbarium records are not accepted by BONAP (2024), nor by Ackerfield (2022). However, in Aug 2024 "Alecsan" photographed a plant on a volcanic ridge 1 mile north of Twelvemile Road in Saguache Co, identified by broomrape specialist Turner Collins as Aphyllon corymbosum subsp. mutabile (see iNaturalist observation #234791504). The USA distribution of the species centers in Nevada, with locations in parts of neighboring states, primarily California, southern Oregon, and Utah. So the Watershed locations would mark the eastern edge of the range. Importantly, Allred et al. (2020) record locations in Rio Arriba and Taos counties of New Mexico, bordering the Watershed. Aphyllon corymbosum does not follow the Rio Grande drainage farther down stream. Note that the genus name Aphyllon was proposed by Adam C. Schneider (2016), who confines the genus Orobanche to Old World species.
