Packera bernardina is a rare species of flowering plant in the aster family known by the common name San Bernardino ragwort.
The perennial herb is endemic to the San Bernardino Mountains of southern California, where it is known from about twenty occurrences.
It grows in mountain pine forests and the unique pebble plain habitat type of the local region. [1] [2]
Packera bernardina is a perennial herb growing 30 to 50 centimeters in maximum height from a branching caudex and a rosette of basal leaves; several rosettes, each with a stem, may be clustered together. The spatula-shaped leaves have small squared oval blades with toothed edges which are borne on the ends of long petioles. Smaller, simpler leaves occur farther up the stem. The leaves are coated in a very short layer of woolly hairs.
The inflorescence contains several flower heads, each lined with hairy green phyllaries. The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each up to a centimeter long. The fruit is an achene with a body about a millimeter long tipped with a pappus of 3 or 4 millimeters. The bloom period is May to July.
Packera obovata, the roundleaf ragwort or spoon-leaved ragwort, is an erect perennial herb native to Eastern North America. It was previously called Senecio obovatus. Basal and lower leaves are obovate with toothed margins, while upper leaves are pinnately divided. The ray flowers are yellow and the disk flowers orange-yellow, the inflorescences being held well above the foliage.
Pyrrocoma uniflora is a species of flowering plant in the aster family known by the common name plantain goldenweed. It is native to western North America from central Canada to California to Colorado, where it grows in several types of habitat, including forest and meadows with alkali soils, such as those near hot springs. It is a perennial herb growing up to 40 centimeters tall, the stems reddish and usually with a thin to thick coating of woolly fibers. The lance-shaped, toothed leaves are usually woolly, the largest near the base of the plant reaching up to 12 centimeters in length. The inflorescence is a single flower head or a cluster of a few heads, each lined with woolly phyllaries. The head contains yellow disc and ray florets. The fruit is an achene which may be over a centimeter long including its long pappus.
Packera bolanderi is a species of flowering plant in the aster family known by the common names Bolander's ragwort and seacoast ragwort. It is native to the west coast of the United States from Washington to northern California, where it grows in wet coastal forests and woodlands. There are two varieties of the species which differ slightly in morphology and habitat occupied; these varieties have been considered separate species by some authors. The var. bolanderi has thicker leaves, occurs farther south, and occupies more open types of habitat, than does var. harfordii. This plant in general is a perennial herb producing one to three stems up to half a meter tall. The basal leaves have blades up to 12 centimeters long which are divided into several lobes and borne on long, thin petioles. Leaves growing farther up the stem are smaller and have more lobes on their blades. The inflorescence contains several flower heads, each lined with dark green phyllaries. The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each over a centimeter long. The fruit is an achene tipped with a pappus of bristles.
Packera breweri is a species of flowering plant in the aster family known by the common name Brewer's ragwort. It is endemic to central California, where it occurs in the woodlands and grasslands of the Central Coast Ranges. They are more frequently found in mid-southern counties of California near the coast, such as Kern or Monterey.
Packera cana is a species of flowering plant in the aster family known by the common name woolly groundsel. It is native to western and central North America, where it can be found in a wide array of habitat types at all elevations from grassland to the alpine climates of mountain peaks.
Packera clevelandii is an uncommon species of flowering plant in the aster family known by the common name Cleveland's ragwort. It is endemic to California, where it is known from only two small regions, a section of the North Coast Ranges around Napa County and a part of the Sierra Nevada foothills on the opposite side of the Sacramento Valley. The plant grows in shrubby chaparral, often on serpentine soils.
Packera subnuda is a species of flowering plant in the aster family known by the common names Buek's groundsel and cleftleaf groundsel. It is native to western North America from the Northwest Territories to northern California to Wyoming, where it grows in high mountain meadows in subalpine and alpine climates.

Packera indecora is a species of flowering plant in the aster family known by the common names elegant groundsel and rayless mountain ragwort. It is native to northern North America including most of Canada and sections of the northernmost United States. It grows in moist mountain habitat, such as streamsides and meadows.
Packera ionophylla is an uncommon species of flowering plant in the aster family known by the common name Tehachapi ragwort. It is endemic to California, where it is known from the Tehachapi Mountains, the San Gabriel and San Bernardino Mountains, and Alamo Mountain near the Grapevine. It grows in mountain forest habitat.

Packera streptanthifolia is a species of flowering plant in the aster family known by the common name Rocky Mountain groundsel. It is native to western North America from Alaska to California to New Mexico, where it can be found in mountain habitat including woodlands and rocky slopes.
Packera werneriifolia, known by the common names alpine rock butterweed and hoary groundsel, is a species of flowering plant in the aster family. It is native to the western United States in the Sierra Nevada mountain habitat in subalpine and alpine climates, including forests and barren talus.
Packera franciscana is a rare species of flowering plant in the aster family known by the common name San Francisco Peaks groundsel, or San Francisco Peaks ragwort. It is endemic to Arizona in the United States, where it is known only from the San Francisco Peaks in Coconino County. It is threatened by recreational activities in its habitat.
