Senecio bigelovii or nodding groundsel or nodding ragwort is a perennial herb native to the Colorado Plateau region of the United States. [1]
Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
Jacobaea vulgaris, syn. Senecio jacobaea, is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere.
Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus Senecio, but were moved to a different genus based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.
Packera aurea, commonly known as golden ragwort or simply ragwort, is a perennial flower in the family Asteraceae.
Senecio viscosus is a herbaceous annual plant of the genus Senecio. It is known as the sticky ragwort, sticky groundsel or stinking groundsel.
Senecio squalidus, known as Oxford ragwort, is a flowering plant in the daisy family Asteraceae. It is a yellow-flowered herbaceous plant, native to mountainous, rocky or volcanic areas, that has managed to find other homes on man-made and natural piles of rocks, war-ruined neighborhoods and even on stone walls. These habitats resemble its well drained natural rocky homeland. The plants have spread via the wind, rail and the activities of botanists. The travels of this short-lived perennial, biennial, or winter annual make it a good subject for studies of the evolution and ecology of flowering plants.
Senecio flaccidus, formerly recorded as Senecio douglasii, member of the daisy family and genus Senecio also known as threadleaf ragwort, is a native of the southwestern Great Plains of North America.
Senecio fremontii, the dwarf mountain ragwort, is a species of the family Asteraceae. It takes its scientific name from John C. Frémont.
Senecio triangularis, known as arrowleaf ragwort, arrowleaf groundsel and arrowleaf butterweed, is a species of the genus Senecio and family Asteraceae.
Senecio scorzonella, known by the common name Sierra ragwort, is a species of the genus Senecio and family Asteraceae which is native to California and Nevada. It grows in the southernmost Cascade Range, the Sierra Nevada, and the White Mountains.
Senecio aphanactis, known by the common names chaparral ragwort, rayless ragwort, and California groundsel, is a species of flowering plant in the aster family.
Senecio astephanus is a species of flowering plant in the aster family known by the common name San Gabriel ragwort. It is endemic to California, where it is known only from the rocky slopes of the Transverse Ranges and adjacent Coast Ranges. It is a perennial herb growing up to a meter tall and producing discoid flower heads containing golden yellow florets.
Senecio blochmaniae is an uncommon species of flowering plant in the aster family known by the common names dune ragwort and Blochman's ragwort. It is endemic to the Central Coast of California, where it is known only from the direct coastline of San Luis Obispo and Santa Barbara Counties. It grows in sand dunes and sandy areas on coastal floodplains. It is a subshrub producing several arching stems often well exceeding a meter tall from a thick taproot. The stems are covered in many leaves, which are linear in shape, thick, and measure up to 12 centimeters long. The lower leaves become dry and curl up. The flower heads are lined by about 13 green-tipped phyllaries. They contain many yellow disc florets and each has usually 8 narrow yellow ray florets about a centimeter long.
Senecio californicus is a species of flowering plant in the aster family known by the common name California ragwort.
Senecio elegans is a species of flowering plant in the aster family known by the common names redpurple ragwort, purple groundsel, wild cineraria and purple ragwort.
Senecio hydrophiloides is a species of flowering plant in the aster family known by the common names tall groundsel and sweet marsh ragwort. It is native to western North America from British Columbia and Alberta to northern California to Utah, where it grows in wet meadows and similar habitat. It is a biennial or perennial herb producing a single erect stem or a cluster of a few stems which may exceed one meter in maximum height. The plants are green to red in color and usually without hairs, but new growth can be woolly. The leaves are lance-shaped to oval with toothed edges, the blades up to 25 centimeters long and borne on long winged petioles. The leaves are firm and sometimes a bit fleshy. The inflorescence is a loose or dense cluster of up to 30 or more flower heads lined with black-tipped phyllaries. They contain many yellowish disc florets at the center and often have some yellow ray florets, though these are sometimes absent. Senecio Hydrophiloides can cause Dermatitis.
Senecio hydrophilus is a species of flowering plant in the aster family known by the common names water ragwort and alkali-marsh ragwort. It is native to western North America from British Columbia to California to Colorado, where it grows in swampy places such as marshes. It can grow in standing water, including alkaline and salty water. It is a biennial or perennial herb producing a single erect stem or a cluster of a few stems which may exceed one meter in maximum height, at times approaching two meters. The stem is hollow, waxy in texture, and often pale green in color, and it emerges from a small caudex. The thick leaves are lance-shaped to oval with smooth or toothed edges, the blades up to 20 centimeters long and borne on petioles. Smaller leaves occur farther up the stem. The inflorescence is one or more large, spreading clusters of many flower heads. They contain many yellowish disc florets at the center and sometimes have small yellow ray florets as well.
Senecio mohavensis, known by the common name Mojave ragwort, is a species of flowering plant in the aster family.
Senecio pattersonensis is an uncommon species of flowering plant in the aster family known by the common names Mono ragwort. and Mount Patterson senecio.
Jacobaea aquatica or Senecio aquaticus, the water ragwort or marsh ragwort, is a plant of the family Asteraceae. It is a perennial or biennial plant: young plants form a rosette near the ground, eventually producing a taller flowering shoot with many bright yellow flower heads, each with prominent ray florets. It grows in damp, grazed grassland, especially where there has been some disturbance.
