Stenotus is a genus of flowering plants in the family Asteraceae. There are four species, all native to western North America. [2] They are known commonly as mock goldenweeds. [2] [3]

These are perennial herbs sometimes forming mats or clumps a few centimeters high, producing erect stems up to about 30 centimeters tall but known to reach 60 centimeters at times. They grow from a taproot and branching caudex. The stems and foliage are hairless to quite woolly, and nonglandular to glandular-hairy. The leaf blades are linear to widely lance-shaped, white near the bases and green or grayish toward the tips. The flower head is solitary, paired, or in an array of up to four. There are yellow disc florets and usually yellow ray florets. The fruit has a pappus of fine white bristles. [2]

The names of two related genera were coined because they are anagrams of the name Stenotus: Nestotus [4] and Tonestus . [5]

Several species one included in Stenotus are now considered to belong to other genera, including Ericameria, Erigeron, Nestotus, Oonopsis, Tonestus, and Townsendia .

Pyrrocoma racemosa is a species of flowering plant in the family Asteraceae known by the common name clustered goldenweed. It is native to the western United States, where it grows in many types of habitat. It is quite variable in morphology, and there are several varieties which are sometimes hard to tell apart. In general, it is a perennial herb usually producing two or more mostly erect stems reaching maximum heights between 15 and 90 centimeters. The stems are reddish or brownish in color, leafy or not, and hairless to quite woolly. The longest leaves are located in tufts around the base of the stems. They are lance-shaped to oval, smooth-edged, wavy, or deeply spine-toothed, and may exceed 30 centimeters in length. Basal leaves are borne on woolly petioles. Leaves located higher on the stem lack petioles and may clasp the stem at their bases. The inflorescence is a cluster of several flower heads lined with phyllaries which may be over a centimeter long and are hairy to hairless in texture. Each head contains many yellow disc florets and a fringe of several yellow ray florets. The fruit is an achene which may be over a centimeter long including its pappus.
