YES Mary E. McDonald: Conejos Co, dry open meadow by Forest Service Road 101, 8,6500' elev. 19 June2019

Comments

There are only two areas in the Watershed for vouchered specimens of Lithophragma tenellum (or Lithophragma tenella): around La Veta Pass and the headwaters of Sangre de Cristo Creek (1900, 1901, 1957); near Hwy 160 in Rio Grande Co (1984)—a total of seven specimens. Ackerfield (2015) and BONAP (2022) show Mineral Co, with no vouchers in SEINet. So the 2019 photorecord from a dry meadow off of FSR 101 would add Conejos Co to counties indicated in Ackerfield (2022) and BONAP (2022). In Colorado the species is more common in the San Juan River drainage, and the Watershed locations stand on the extreme eastern edge of the USA range. L. tenellum follows the Rio Grande drainage only as far as Rio Arriba and Taos counties of New Mexico, bordering Colorado.
