flatspine stickseed, Lappula occidentalis

These little flowers are a miniature version of yesterday's catseye. They're at most an eighth of an inch across. They grow in the same sandy and rocky soils, and it's not unusual to see them together. That was the case on this roadside on the trip from Silverthorn to Gunnison. This is a western plant, becoming weedy in the east. It has been reported from AK, AR, AZ, CA, CO, CT, IA, ID, IL, KS, ME, MN, MO, MT, ND, NM, NV, NY, SC, SD, TX, UT, WA, WI, WY, AB, BC, MB, and SK.
