Prenanthes is a genus of plant in the family Asteraceae, often referred to as rattlesnake root. [2] [3]

Molecular analysis in 2009 revealed that the genus as traditionally envisioned is polyphyletic, meaning that it is a conglomeration of species not closely related to one another. All but one species will be moved to other genera, leaving only Prenanthes purpurea. [4] The species, sometimes called purple lettuce, [5] is widespread across much of Europe and the Middle East. [6]

The genus formerly included; [1] Aetheorhiza, Askellia, Brickellia, Chondrilla, Crepidiastrum, Crepis, Emilia, Erythroseris, Faberia, Hololeion, Hypochaeris, Ixeris, Kovalevskiella, Lactuca, Lapsanastrum, Launaea, Lygodesmia, Nabalus, Notoseris, Paraprenanthes, Parasenecio, Picrosia, Sonchella, Sonchus, Soroseris, Stephanomeria, Trixis, and Youngia

<i>Echinacea</i> Genus of flowering plants in the daisy family Asteraceae

Echinacea is a genus of herbaceous flowering plants in the daisy family. It has ten species, which are commonly called coneflowers. They are found only in eastern and central North America, where they grow in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming in summer. The generic name is derived from the Greek word ἐχῖνος, meaning "hedgehog", due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Two of the species, E. tennesseensis and E. laevigata, were formerly listed in the United States as endangered species; E. tennesseensis has been delisted due to recovery and E. laevigata is now listed as threatened.

It is related to common lettuce, and is often called wild lettuce, bitter lettuce, laitue vireuse, opium lettuce, poisonous lettuce, tall lettuce, great lettuce or rakutu-karyumu-so.

<i>Molinia caerulea</i> Species of grass

It grows in locations from the lowlands up to 2,300 m (7,546 ft) in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain and Ireland. Introduced populations exist in northeastern and northwestern North America.

<i>Nabalus albus</i> Species of flowering plant

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.

<i>Echinacea purpurea</i> Species of flowering plant in the daisy family Asteraceae

<i>Ipomoea hederacea</i> Species of flowering plant

Ipomoea hederacea, the ivy-leaved morning glory or Kaladana, is a flowering plant in the bindweed family. The species is native to tropical parts of the Americas, and has more recently been introduced to North America. It now occurs there from Arizona to Florida and north to Ontario and North Dakota. Like most members of the family, it is a climbing vine with alternate leaves on twining stems. The flowers are blue to rose-purple with a white inner throat and emerge in summer and continue until late fall. The leaves are typically three-lobed, but sometimes may be five-lobed or entire. Flowers occur in clusters of one to three and are 2.5-4.5 cm long and wide. The sepals taper to long, recurved tips and measure 12–24 mm long. The species shares some features with the close relative Ipomoea purpurea, and is almost identical in appearance to wild forms of I. nil.
