Rorippa amphibia, also known as great yellow-cress, is a plant species in the family Brassicaceae. [1] The flowers are visited by many types of insects, and can be characterized by a generalized pollination syndrome. [2]
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, for example beetles; birds, butterflies, and bats; water; wind; and even plants themselves. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants. When self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work.
Rorippa is a genus of flowering plants in the family Brassicaceae, native to Europe through central Asia, Africa, and North America. Rorippa species are annual to perennial herbs, usually with yellow flowers and a peppery flavour. They are known commonly as yellowcresses.
Trifolium pratense, red clover, is a herbaceous species of flowering plant in the bean family Fabaceae, native to Europe, Western Asia, and northwest Africa, but planted and naturalized in many other regions.
Silene flos-cuculi, commonly called ragged-robin, is a perennial herbaceous plant in the family Caryophyllaceae. It is native to Eurasia and has been introduced to North America.
Silene dioica, known as red campion and red catchfly, is a herbaceous flowering plant in the family Caryophyllaceae, native to Europe and introduced to the Americas.
Carrion flowers, also known as corpse flowers or stinking flowers, are mimetic flowers that emit an odor that smells like rotting flesh. Apart from the scent, carrion flowers often display additional characteristics that contribute to the mimesis of a decaying corpse. These include their specific coloration, the presence of setae and orifice-like flower architecture. Carrion flowers attract mostly scavenging flies and beetles as pollinators. Some species may trap the insects temporarily to ensure the gathering and transfer of pollen.
Krameria is the only genus in the Krameriaceae family, of which any of the approximately 18 species are commonly known as rhatany, ratany or rattany. Rhatany is also the name given to krameria root, a botanical remedy consisting of the dried root of para rhatany or Peruvian rhatany.
Stapelia gigantea is a species of flowering plant in the genus Stapelia of the family Apocynaceae. Common names include Zulu giant, carrion plant and toad plant. The plant is native to the desert regions of South Africa to Tanzania.
Stachys palustris, commonly known as marsh woundwort, clown's woundwort, clown's heal-all, marsh hedgenettle, or hedge-nettle, is an edible perennial grassland herb growing to 80 centimeters tall. It is native to parts of Eurasia but has been introduced to North America. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.
Solanum rostratum is a species of nightshade that is native to the United States and northern and central Mexico. Common names include buffalobur nightshade, buffalo-bur, spiny nightshade, Colorado bur, Kansas thistle, bad woman, Mexican thistle, and Texas thistle.
Rorippa palustris, marsh yellow-cress, bog yellow-cress or common yellow-cress, is a species of flowering plant in the family Brassicaceae. It is widespread and native to parts of Africa, and much of Asia, Europe and Eurasia, North America and the Caribbean. It can also be found in other parts of the world as an introduced species and a common weed, for example, in Australia and South America. It is an adaptable plant which grows in many types of damp, wet, and aquatic habitat. It may be an annual, biennial, or perennial plant, and is variable in appearance as well.
Rorippa columbiae is a species of flowering plant in the family Brassicaceae known by the common names Columbian yellowcress and Columbia yellow cress.
Rorippa curvipes is a species of flowering plant in the family Brassicaceae known by the common name bluntleaf yellowcress. It is native to much of western North America from Alaska to Mexico to the Mississippi River, where it can be found in various types of moist and wet habitat, including lakeshores and riverbanks, meadows, roadsides, mudflats, and irrigation ditches. It is an annual or perennial herb, producing several stems growing prostrate along the ground or somewhat upright, measuring 10 centimeters to around half a meter in maximum length. The leaves are long and narrow, smooth edged or lobed, the lobes sometimes cut all the way to the midrib or separated to form leaflets. Lower leaves are borne on petioles; upper leaves have bases that clasp the stem. The mustardlike flowers have very small yellow petals. The fruit is a plump, hairless silique containing many minute seeds.
Rorippa curvisiliqua is a species of flowering plant in the family Brassicaceae known by the common name curvepod yellowcress.
Rorippa sinuata is a species of flowering plant in the family Brassicaceae known by the common name spreading yellowcress. It is native to North America, including most all of the western and central United States, where it grows in many types of moist and wet habitat, such as lakeshores and riverbanks, meadows, and mudflats. It is a perennial herb producing spreading stems up to 40 or 50 centimeters long. It is densely hairy, the hairs rounded like sacs or vesicles. The leaves are up to 8 centimeters long and have blades are deeply toothed, lobed, or divided into smaller leaflets. The inflorescence is an elongated raceme occupying the top portion of the stem containing many tiny yellow flowers just a few millimeters long. The fruit is a curved silique which is variable in size and shape but generally contains many minute seeds.
Rorippa sphaerocarpa is a species of flowering plant in the family Brassicaceae known by the common name roundfruit yellowcress. It is native to North America, including the western United States and northern Mexico, where it grows in moist habitat, such as riverbanks and mudflats. It is an annual herb producing decumbent or erect stems up to 40 centimeters long. The leaves are up to 10 centimeters long and have blades are deeply divided into toothed lobes. The inflorescence is a raceme of mustardlike flowers with yellow petals each no more than a millimeter long. The fruit is a round silique 1 or 2 millimeters wide.
Rorippa subumbellata is a rare species of flowering plant in the family Brassicaceae known by the common names Lake Tahoe yellowcress and Tahoe yellow cress. It is known only from the shores of Lake Tahoe, straddling the border between California and Nevada. There are an estimated fourteen populations of the plant still in existence. It grows only on the direct shoreline of the lake, occupying a seven-foot semi-aquatic zone between the high- and low-tide marks. It is directly impacted by recreational activities on the lake, enduring bombardment by boat wakes, trampling, and construction of docks and other structures.
Rorippa barbareifolia, the hoary yellowcress, is a plant species reported from Manchuria, Inner Mongolia, Mongolia, Siberia, Alaska, Yukon and Saskatchewan. It grows in wet habitats. It can be found along forest borders, in ditches, on stream banks, etc.
Rorippa microtitis, the Chihuahuan yellowcress, is a plant species native to Chihuahua, Arizona and New Mexico. It is widespread in Arizona but has been recorded from only one county in New Mexico (Catron).
