Eriogonum is the scientific name for a genus of flowering plants, in the family Polygonaceae. Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid Caryophyllales is an order of Flowering plants that includes the cacti, carnations Amaranths Ice plants and most Polygonaceae is a family of flowering plants also known as the "knotweed family" or "smartweed family" André Michaux (8 March 1746&ndashprobably 11 October 1802 was a French botanist and Explorer. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Polygonaceae is a family of flowering plants also known as the "knotweed family" or "smartweed family" The genus is found in North America and is known as Wild Buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. Speciation is the Evolutionary process by which new biological Species arise It includes some common wildflowers such as the California Buckwheat (Eriogonum fasciculatum). A wildflower (or wild flower) is a Flower that grows wild meaning it was not intentionally seeded or planted Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and Eastern Mojave buckwheat.
It came into the news in 2005 when the Mount Diablo Buckwheat (Eriogonum truncatum, believed to be extinct) was rediscovered. Year 2005 ( MMV) was a Common year starting on Saturday (link displays full calendar of the Gregorian calendar. Mount Diablo buckwheat ( Eriogonum truncatum) is a small pink flower believed to have been extinct since 1936 until its rediscovery in 2005
Importance for Lepidoptera
Eriogonum species are used as food plants by the larvae of some Lepidoptera (butterflies and moths). A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example Lepidoptera is an order of Insect that includes Moths and butterflies. Several of these are monophagous, meaning that their caterpillars only feed on this genus, sometimes just on a single taxon of Eriogonum. Caterpillars are the Larval form of a member of the order Lepidoptera (the Insect order comprising butterflies and Moths A taxon (plural taxa) or taxonomic unit, is a name designating an organism or a group of Organisms In Biological nomenclature according to Wild buckwheat flowers are also an important source of food for these and other Lepidoptera. In some cases, the relationship is so close that Eriogonum and dependent Lepidoptera are in danger of coextinction. Coextinction of a Species is the loss of one species upon the Extinction of another
Monophagous Lepidoptera on wild buckwheat include:
- Apodemia mormo (Mormon metalmark) - feeds exclusively on Eriogonum
- Apodemia mormo langei (Lange's metalmark) - only known from Eriogonum nudum ssp. Apodemia mormo langei, also known as Lange's Metalmark Butterfly, is an endangered North American butterfly auriculatum
- Chionodes dammersi - feeds exclusively on Eriogonum
- Chionodes luteogeminatus - only known from Eriogonum niveum
- Euphilotes enoptes smithi (Smith's blue butterfly) - only known from Eriogonum latifolium and Eriogonum parvifolium
