Packera musiniensis is a rare species of flowering plant in the aster family known by the common names Musinea ragwort and Musinea groundsel. It is endemic to Utah in the United States, where it is known only from Sanpete County in the Manti-La Sal National Forest.[1]
This dwarf perennial herb has a woolly-haired white stem a few centimeters tall with lance-shaped basal leaves 2 or 3 centimeters long. They have ruffled or nearly lobed edges. The inflorescence contains 3 to 15 flower heads on woolly peduncles. Each head is lined with yellow-green to purple phyllaries nearly a centimeter in length. There is no more than one ray floret; this may be absent. Blooming occurs in July and August.[2]
This plant occurs along the Wasatch Plateau and on Musinea Peak in central Utah. There are four occurrences, three of which are believed to be extant. It grows in subalpine and alpine climates on limestone substrates.[1]
