is an uncommon species, of conservation concern, found in rocky places near the Arizona/Nevada/Utah border; Zion National Park is one such location, hence the common name of Springdale rockdaisy. It is also quite common in the Beaver Dam Mountains of northwestern Arizona.
Leaves and stems have a moderate to dense covering of short, non-glandular hairs. The rayless flowerheads may be single but are usually in small clusters, of up to ten. Peduncles are around one inch in length. Phyllaries, 13 to 20, are in one series; they are linear in shape, pointed at the tip, and also short hairy. The yellow disc florets number from 23 to 35, occasionally more.
