NEED IN SITU PHOTOS. In 1991 W. A. Weber found Coresipermum hyssopifolium in abundant numbers in the sandy soil of roadside ditches between the towns of San Luis and Sanford (Alamosa Co). In 1986, Dixon found it in the Great Sand Dunes NM (Alamosa Co). Ackerfield (2022) inicates Conejos Co, with no SEINet vouchers. In the USA, this species is endemic to Colorado, with observations, for instance, in Platte, Pueblo, Weld, Gunnison, and El Paso counties (1878-2003). The species is also European and it is sometimes taken as introduced to the USA, but the distinction between the Old World Corispermum hyssopifolium (Linnaeus) and New World specimens identified as such remains problematic. FNA says, "No unquestionable specimens of Corispermum hyssopifolium sensu stricto are known from North America."
