Other info. - If you want to view this plant in this state you will have to travel up to Holt and Atchison Counties in the northwest corner of the state. The plant can be found on the upper ridges of the loess hills in the area. Good luck if you go out there.
This plant may not have an abundance of magnificent color to look at but it is an interesting little plant regardless. The flowers are inconspicuous but the scraggly bracts and ascending stems give the plant a "spidery" appearance.
