About Packera streptanthifolia (Greene) W.A.Weber & Á.Löve
Packera streptanthifolia is a species of flowering plant in the aster family, commonly known as Rocky Mountain groundsel. It is native to western North America, ranging from Alaska to California to New Mexico, where it grows in mountain habitats such as woodlands and rocky slopes. This perennial herb typically produces one erect stem, and sometimes grows a small cluster of a few stems, reaching a maximum height of 10 to 60 centimeters. Its basal leaves are spatula-shaped, with oval or lance-shaped blades held on long petioles. These basal leaves are thick, firm, and sometimes slightly succulent. Leaves positioned higher on the stem are smaller, thinner, and simpler in structure, and may not have petioles. The inflorescence is a loose arrangement of two or more flower heads, which contain yellow disc florets and usually either 8 or 13 yellow ray florets, each up to one centimeter long. This species is named for its foliage, which resembles that of certain Streptanthus species, typically bearing somewhat succulent oval leaves with rounded teeth at the tip.
