Cuscuta californica | |
Cuscuta californica is a species of dodder known by the common names chaparral dodder and California dodder. This is an annual parasitic plant that may resemble fine strands of spaghetti or twine strewn across other species in its habitat. A mature plant of this species may fulfill all of its food and water needs from the host plant, but they rarely kill their host. [1] It is native to western United States and Baja California in Mexico.
Cuscuta californica is a parasitic vine which climbs other plants and takes nutrition directly from them via a haustorium. The dodder resembles a pile of yellow-orange straw wrapped tightly around its host plant. It is mostly stem; the leaves are reduced to scales on the stem's surface, since they are not needed for photosynthesis while the dodder is obtaining nutrients from its host.
It bears tiny white flowers which are only about 3 millimeters wide, and fruits which are even smaller. The flowers can be used as a diagnostic feature in determining the species of dodder; on C. californica, the calyx length is 3⁄4 to equaling the length of the corolla. The corolla lobes are also equaling or longer than the corolla tube, and the filaments are 0.6 to 1.1 mm long. [2]
Although this species spends most of its life without any contact with the soil, it is borne from a normal, rooted seed. The seed contains minimal energy reserves, meaning seedlings must locate and parasitize a host within a matter of days. It accomplishes this by means of "foraging" patterns, as dodder seedlings can detect the volatile compounds emitted by host plants. Dodder seedlings are even capable of "selecting" host plants based on their compounds emitted. After it attaches itself to the host, the grounded root dies and the plant becomes completely dependent on the host for nutrition. [3] This species flowers from March to September. [2]
There are three recognized varieties of this species: [4]
This species is found throughout the western United States and parts of Mexico. In the United States, it is found in Arizona, California, Nevada, Oregon, Utah and Washington. In Mexico, it is primarily found in the northwestern portion of the state of Baja California. [5] It grows on numerous herbs and shrubs from various habitats, including sandy desert areas, chaparral, coastal sage scrub, grasslands, forests of Pinus ponderosa , and can be found in weedy, partially disturbed areas like roadsides. [2] Like most other dodders, this species is considered a noxious weed in many areas. It was also discovered in Flowood, Mississippi on August 12, 2022.
Cuscuta, commonly known as dodder or amarbel, is a genus of over 201 species of yellow, orange, or red parasitic plants. Formerly treated as the only genus in the family Cuscutaceae, it now is accepted as belonging in the morning glory family, Convolvulaceae, on the basis of the work of the Angiosperm Phylogeny Group. The genus is found throughout the temperate and tropical regions of the world, with the greatest species diversity in subtropical and tropical regions; the genus becomes rare in cool temperate climates, with only four species native to northern Europe.
Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.
Juniperus californica, the California juniper, is a species of juniper native to southwestern North America.
Cassytha is a genus of some two dozen species of obligately parasitic vines in the family Lauraceae. Superficially, and in some aspects of their ecology, they closely resemble plants in the unrelated genus Cuscuta, the dodders. When fruit and flowers are absent in the field, the physical resemblance is so close that few people without technical training can discern the difference. In this respect and in their ecology the two genera present a spectacular example of convergent evolution. Nonetheless, Nickrent comments that "Cassytha is uneqivocally assigned to Lauraceae based on (both) morphological and molecular data." In its divergence from habits typical of the Lauraceae, Cassytha also presents examples of mosaic evolution
Adenostoma fasciculatum, commonly known as chamise or greasewood, is a flowering plant native to California and Baja California. This shrub is one of the most widespread plants of the California chaparral ecoregion. Chamise produces a specialized lignotuber underground and at the base of the stem, known as a burl, that allow it to resprout after fire has off burned its stems. It is noted for its greasy, resinous foliage, and its status as one of California's most iconic chaparral shrubs.
Amorpha californica is a species of flowering plant in the legume family known by the common name California false indigo.
Cuscuta europaea, the greater dodder or European dodder, is a parasitic plant native to Europe, which belongs to the family Convolvulaceae, but was formerly classified in the family Cuscutaceae. It grows on Asteraceae, Cannabaceae, Chenopodiaceae, Fabaceae, Urticaceae and other herbaceous plants, including garden plants such as Coleus and Impatiens, and more occasionally on Humulus. It is a notable parasite of lucerne. In many regions, including the Nepal Eastern Himalayas, this species are used as traditional medicine to treat hepatic diseases.
Cuscuta epithymum is a parasitic plant assigned to the family Cuscutaceae or Convolvulaceae, depending on the taxonomy. It is red-pigmented, not being photosynthetically active. It has a filiform habit, like a group of yarns. Its leaves are very small, like flakes. Its flowers, disposed in little glomerules, have a white corolla, with the androecium welded to the corolla.
Cuscuta salina is a species of dodder known by the English name salt marsh dodder and is a native plant of western North America. The habitat includes coastal tidal wetlands in California, as well as saline habitats away from the coast, such as vernal pools and salt flats. Salt Marsh Dodder is a parasitic plant, wrapping orange-colored stems around natural wetland vegetation and absorbing nutrients of host plants via their specialized structures called haustoria.
Cuscuta campestris, with the common names field dodder, golden dodder, large-seeded alfalfa dodder, yellow dodder and prairie dodder, is a parasitic plant which belongs to the family Convolvulaceae. It was formerly classified in the family Cuscutaceae.
Xylococcus is a monotypic genus of flowering plants in the heather family which contains the single species Xylococcus bicolor, commonly known as the mission manzanita. It is a burl-forming, evergreen shrub with leathery leaves and smooth dark reddish bark. From December to February, white to pink urn-shaped flowers adorn the foliage, often attracting hummingbird pollinators. It is native to southern California and the Baja California Peninsula, south to the Sierra de la Giganta. There is growing concern over the future of this plant, referred to as the "queen of the elfin forest, " as it may possibly lose up to 88% of its habitat and its wild seedlings are failing to survive more than a full year.
Ceanothus prostratus is a species of shrub in the family Rhamnaceae. Common names include prostrate ceanothus, pinemat, and mahala mat. It is native to the Pacific Northwest of the United States where it grows in coniferous forests and open plateaus.
Cylindropuntia californica is a species of cholla cactus known by the common name snake cholla. It is primarily found in Baja California, Mexico and the southernmost part of California in the United States. It is characterized by a short, decumbent habit, yellow-green flowers, elongated stems, and short spines. It is mostly found in coastal sage scrub and coastal chaparral habitats, but two varieties in Baja California can be found in foothills and deserts. In California, variety californica is regarded as a rare and threatened plant, with a California Native Plant Society listing of 1B.1, in part due to its limited number of occurrences and threats from development. It formerly was considered to have a larger range due to the inclusion of Cylindropuntia bernardina within it as the variety parkeri.
Orobanche californica, known by the common name California broomrape, is a species of broomrape. It is a parasitic plant growing attached to the roots of other plants, usually members of the Asteraceae.
