It is native to western North America from far southwestern British Columbia to Baja California, where it grows in seasonally wet habitat, such as vernal pools, as well as coastline and disturbed areas.
Stephanomeria cichoriacea is a species of flowering plant in the aster family; it is known by the common names chicoryleaf wirelettuce and silver rock-lettuce. It is endemic to California, where it grows in the coastal mountain ranges as far north as Monterey County, but especially in southern California mountains such as the Transverse Ranges. Its habitat includes chaparral. It is a perennial herb producing slender erect stems reaching maximum heights exceeding one meter. The stem is woolly with hairs, especially on new growth. The leaves are mostly located in a basal rosette, the largest reaching 18 to 20 centimeters long. They are lance-shaped and often toothed along the edges, and the newer ones are woolly. Smaller leaves occur farther up the stem. The inflorescence is a long array of several flower heads, with some occurring in the upper leaf axils as well. Each head has a cylindrical base 1 to 2 centimeters long which is lined with layers of glandular phyllaries. The head contains 10 to 15 ray florets, each with an elongated tube and a pink ligule which may be up to 2 centimeters long. The fruit is an achene tipped with a spreading cluster of long, plumelike pappus bristles.
Stylocline citroleum is a rare species of flowering plant in the family Asteraceae known by the common name oil neststraw.
Stylocline intertexta is a species of flowering plant in the family Asteraceae known by the common names Morefield's neststraw and Mojave neststraw. It is native to the Mojave and Sonoran Deserts of California, Nevada, Utah, and Arizona, where it grows in rocky, sandy desert soils. It likely evolved as a hybrid between woollyhead neststraw and baretwig neststraw ; it is a mix of their morphological traits and it occurs alongside both of them. It reproduces itself, producing fertile offspring, and it meets other criteria for any other definition of a species, so it was described to science as such in 1992. It is a small annual herb growing at ground level and reaching just a few centimeters in length. It is usually coated in white hairs, often woolly. The small, pointed leaves are oval to lance-shaped and measure up to 1.5 centimeters long. The inflorescence bears spherical flower heads each a few millimeters in diameter. The head has no phyllaries, just a ball of tiny woolly white flowers.

Stylocline micropoides is a species of flowering plant in the family Asteraceae known by the common names woollyhead neststraw, woollyhead fanbract and desert neststraw. It is native to the southwestern United States and northern areas in the northern states of Mexico, where it grows in desert habitat and other dry areas. It is a small annual herb growing at ground level with stems up to 20 centimeters in length. It is woolly or felt-like in texture with a coating of white hairs. The pointed leaves are up to 2 centimeters long and alternately arranged. The inflorescence bears spherical flower heads no more than a centimeter in diameter. The head generally has no phyllaries, or has small ones that fall away early. It contains several woolly white flowers.
Stylocline psilocarphoides is a species of flowering plant in the family Asteraceae known by the common names baretwig neststraw and Peck's neststraw. It is native to the western United States from Idaho to southeastern California, where it grows in deserts and other dry, sandy, gravelly habitat. It is a small annual herb growing at ground level with stems measuring 1 to 18 centimeters in length. It is woolly or felt-like in texture with a coating of white hairs. The pointed leaves are up to 1.8 centimeters long and alternately arranged. The inflorescence bears oval flower heads no more than half a centimeter in diameter. The head generally has no phyllaries, or has small ones that fall away early. It is a hardened ball of several woolly white flowers.
Tetradymia argyraea is a species of flowering plant in the aster family known by the common names striped cottonthorn and striped horsebrush. It is native to the desert mountains of the southwestern United States, particularly of California, Nevada, and Arizona, where it grows in desert woodland habitat. It is a woolly, spiny shrub growing one half to nearly two meters in maximum height. The erect stems are white-woolly except for bare stripes at intervals. The leaves are linear in shape and harden as they age, becoming spiny. The larger leaves are woolly and there are clusters of smaller, threadlike leaves which may be hairless. The inflorescence bears two to five flower heads which are each enveloped in five thick phyllaries coated in white woolly hairs. Each head contains five pale yellow flowers each around a centimeter long. Flowers are produced in summer, as late as September. The fruit is an achene a few millimeters long tipped with a pappus of bristles.
Tetradymia comosa is a species of flowering plant in the aster family, known by the common name hairy horsebrush.
Tricardia is a monotypic genus of flowering plants in the borage family containing the single species Tricardia watsonii, which is known by the common name threehearts. It is native to the southwestern United States, where it grows in deserts and mountains in sandy open habitat, often beneath shrubs. It is a perennial herb growing from a taproot and a woody caudex covered with the shreddy remains of previous seasons' herbage. It produces several erect stems up to about 40 centimeters tall. Most of the leaves are located in a basal rosette about the caudex. They are lance-shaped and coated thinly in woolly hairs. They are up to 9 centimeters long and are borne on petioles. A few smaller leaves occur higher on the stem. Flowers occur in a loose cyme at the top of the stem. Each has a calyx of five sepals. The outer three are heart-shaped and green to pink or purple in color, and the inner two are much smaller and narrower. The flower within is bell-shaped, white with central purple markings, and roughly half a centimeter wide. The fruit is a capsule just under a centimeter long which contains 4 to 8 seeds.
