Poaceae

Cenchrus longispinus (Hack.) Fern.  Longspine Sandbur.

DeLong Park (City of Golden), Jefferson County, Colorado. In planted native grass beds, along 23rd Street, opposite Vernon Drive, 1.72 km. southeast of the GNIS location of Golden. 39.74893°N, 105.20797°W. WGS 1984 Elev. 1765 m. Annual grass, collected in its second growing season at this site, suggesting it is naturalized here. Native to Colorado, but usually found in sandy habitats. Not previously collected at any other location in or near Golden; unclear whether this grass was previously here, brought in with the soil amendment, or was a contaminant in the seed mix. DeLong Park was a private residence that was left fallow for a number of years, then converted to a city park in 2021-2022.

Collected by permit: City of Golden, 2023, issued: Mar 13, 2023, to: Tom Schweich.
