Count Alexandre Henri Gabriel de Cassini was a French botanist and naturalist, who specialised in the sunflower family (Asteraceae).
Rudbeckia is a plant genus in the Asteraceae or composite family. Rudbeckia flowers feature a prominent, raised central disc in black, brown shades of green, and in-between tones, giving rise to their familiar common names of coneflowers and black-eyed-susans. All are native to North America, and many species are cultivated in gardens for their showy yellow or gold flower heads that bloom in mid to late summer.
Liatris, commonly known as gayfeather and blazing star is a genus of flowering plants in the tribe Eupatorieae within the family Asteraceae native to North America. Some species are used as ornamental plants, sometimes in flower bouquets. They are perennials, surviving the winter and resprouting underground corms.
Liatris aspera is a perennial wildflower in the Asteraceae family that is found in central to eastern North America in habitats that range from mesic to dry prairie and dry savanna.
Nabalus albus, the white rattlesnake-root, also known as Boott's rattlesnake-root or white lettuce, is a plant in the family Asteraceae, native to Canada and the Eastern United States. Details of the flower heads are needed to separate this species from others in the rattlesnake-root genus (Nabalus). The Iroquois applied a poultice of the roots of white rattlesnake root to rattlesnake bites. It can be found growing in forests, woodlands, and anthropogenic habitats. The flower head has ray flowers only, meaning all of the individual flowers of the flower head have a strap-shaped ray, which may or may not have teeth at the very tip of the ray. The colors vary from blue to purple, pink to red, or white. The leaf blade length can be between 40 and 300 mm. while the flower head width can be 3 to 5 mm. Blooms from July to September in Missouri. In 2010 it was reclassified from the genus Prenanthes to Nabalus.
Prenanthes is a genus of plant in the family Asteraceae, often referred to as rattlesnake root.
Eurybia radula, commonly known as the low rough aster or rough wood aster, is an herbaceous perennial in the family Asteraceae. It is native to eastern North America where it is present from Newfoundland and Labrador in the far northeast of Canada, west to Ontario and south to Kentucky and Virginia in the United States. The low rough aster is also present on the French overseas territory of St. Pierre and Miquelon just south of Newfoundland. It typically grows in wet soils in a wide variety of habitats from bogs and fens to creek shores to ditches. Although it is not considered threatened over most of its distribution, it is imperiled or possibly extirpated over much of its range in the United States. Its flower heads emerge in the late summer to early fall and show pale blue-violet rays with yellow centres.
Psiadia, commonly known as daisy trees, is a genus of mostly woody Asian and African plants in the tribe Astereae within the family Asteraceae. The genus is distributed throughout the Western Indian Ocean, with species reported from continental Eastern Africa, Madagascar, Mauritius, La Reunion, Rodrigues, the Comoro islands, as well as several of the smaller, uninhabited islands in the Mozambique Channel. Additional species are suspected on Socotra and Sri Lanka, but these have not been confirmed. Phylogenetic studies using DNA sequence data and biogeographic reconstruction using molecular dating have shown that the genus originated on the African mainland, and colonized Madagascar and the outlying islands in the Indian Ocean in several independent instances of overwater dispersal in the Miocene.
Berlandiera is a genus of flowering plants in the family Asteraceae.
The Cichorieae are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera Gundelia and Warionia only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are Taraxacum with about 1,600 apomictic species, Hieracium with about 770 sexually reproducing and 5,200 apomictic species, and Pilosella with 110 sexually reproducing and 700 apomictic species. Well-known members include lettuce, chicory, dandelion, and salsify.
Helianthus divaricatus, commonly known as the rough sunflower, woodland sunflower, or rough woodland sunflower, is a North American species perennial herb in the family Asteraceae. It is native to central and eastern North America, from Ontario and Quebec in the north, south to Florida and Louisiana and west to Oklahoma and Iowa.
Carphephorus is a genus of North American plants in the family Asteraceae. They are native to the southeastern United States from Louisiana to Virginia. Plants of this genus are known commonly as chaffheads.
Solidago rugosa, commonly called the wrinkleleaf goldenrod or rough-stemmed goldenrod, is a species of flowering plant in the family Asteraceae. It is native to North America, where it is widespread across eastern and central Canada and the eastern and central United States. It is usually found in wet to mesic habitats.
Mulgedium is a genus of flowering plants in the dandelion tribe within the sunflower family.
Nabalus is a genus of Asian and North American flowering plants in the tribe Cichorieae within the family Asteraceae.
Aphananthe aspera, commonly known as scabrous aphananthe or muku tree, is a flowering plant in the family Cannabaceae. It is found on slopes and stream banks between 100 and 1600 m. It is native to China, Taiwan, Japan, Korea, and Vietnam.
Nabalus barbatus, the barbed rattlesnakeroot, is a plant in the family Asteraceae. It is native to the Southeastern United States where it is found in small numbers in a few disjunct areas of remaining natural grassland. Because of this, it is considered a globally rare species, with only 35-70 remaining populations. Much of its natural habitat of prairie and savanna has been destroyed. In 2010 it was reclassified from the genus Prenanthes to Nabalus.
Nabalus crepidineus, commonly called the nodding rattlesnakeroot, is a species of flowering plant in the family Asteraceae. It is native to the United States, where it is found in the Midwest and Upland South regions. Its natural habitat is in bottomland and mesic forests, and along streambanks.
Nabalus altissimus, commonly called the tall rattlesnakeroot or white lettuce, is a species of plant in the family Asteraceae. In 2010 it was reclassified from the genus Prenanthes to Nabalus.
Nabalus trifoliolatus, the gall-of-the-earth or three-leaved rattlesnake root, is a species of flowering plant in the family Asteraceae, native to eastern Canada and the eastern United States. It is a perennial reaching 5 ft (1.5 m).
