Eriogonum elongatum, commonly known as longstem buckwheat or wand buckwheat, is a species of wild buckwheat native to coastal southern and Baja California. [1] [2] [3] [4] [5]
Eriogonum elongatum is a perennial herb reaching a height of 0.6–1.2 meters (2.0–3.9 feet) with cauline leaves approximately 1–3 centimeters (0.39–1.18 inches) long and 0.5–2 centimeters (0.20–0.79 inches) wide. Its leaves and stem are generally tomentose. [4] It has a haploid number of n=34. [4]
Eriogonum elongatum primarily grows in coastal sage scrub, foothill woodland, and chaparral ecosystems in and around the Coast, Transverse, and Peninsular Ranges of California from 60–1,900 metres (200–6,230 feet) above sea level. [1] [4] As with many other Eriogonum species, Eriogonum elongatum is a bodenvag species, tolerant of a relatively wide pH range of 5–8.2, [6] and is tolerant of serpentinite soils that are common throughout its range, though it is not endemic to serpentine-derived soils. [7]
Eriogonum elongatum supports several organisms in its habitat, including native bees, parasitic and predatory insects, and butterflies. Hosted butterflies include the Mormon metalmark (Apodemia mormo), Bramble Hairstreak Butterfly (Callophrys perplexa), Comstock's Hairstreak (Callophrys sheridanii comstocki), Bernardino Dotted-Blue (Euphilotes bernardino), Small Dotted-Blue (Philotiella speciosa), Acmon Blue (Plebejus acmon), and Lupine Blue (Plebejus lupini). [6]
Eriogonum elongatum has three described varieties: [8]
Eriogonum is a genus of flowering plants in the family Polygonaceae. 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. It includes some common wildflowers such as the California buckwheat.
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.
Eriogonum parvifolium is a species in the family Polygonaceae that occurs on dune formations in the coastal area of Central and Southern California. This evergreen shrub grows to a height of 30 to 100 centimeters with a spread of approximately the same dimension. This plant is an important host for a number of pollinating insects including certain endangered species. E. parvifolium occurs both on bluffs along the Pacific Ocean coast as well as Coastal Strand dunes formations, but is restricted to altitudes below 700 meters. In at least one instance within the Carbonera Creek watershed, it occurs farther inland in a Maritime Coast Range Ponderosa Pine forest. This shrub is also known by the common names dune buckwheat, coast buckwheat, cliff buckwheat, or seacliff buckwheat.
Rubus ursinus is a North American species of blackberry or dewberry, known by the common names California blackberry, California dewberry, Douglas berry, Pacific blackberry, Pacific dewberry and trailing blackberry.
Ceanothus cuneatus is a species of flowering shrub known by the common names buckbrush and wedgeleaf ceanothus.
Eriogonum apricum is a rare species of wild buckwheat known by the common name Ione buckwheat. It is endemic to Amador County, California, in the United States.
Eriogonum arborescens is a species of wild buckwheat known by the common name Santa Cruz Island buckwheat.
Eriogonum cinereum is a species of wild buckwheat known by the common names coastal buckwheat and ashyleaf buckwheat.
Eriogonum giganteum, with the common name St. Catherine's lace, is a species of wild buckwheat in Southern California.
Eriogonum ovalifolium is a species of wild buckwheat known by the common name cushion buckwheat. It is native to western North America from California to Alberta, where it is a member of many plant communities in varied habitats, including the sagebrush steppe and alpine regions.
Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower. It is native to western North America from California to Colorado to central Canada, where it is abundant and found in many habitats, including the sagebrush steppe and alpine areas. It is an extremely variable plant and hard to identify because individuals can look very different from one another. Also, there are many varieties. It may be a perennial herb blooming by summer with stems 10 centimeters tall and two to six clusters of flowers, with a whorl of leaves below the stems, or a sprawling shrub approaching two meters high and wide. The leaves are usually woolly and low on the plant, and the flowers come in many colors from white to bright yellow to purple.
Eriogonum kelloggii is a rare species of wild buckwheat known by the common names Red Mountain buckwheat and Kellogg's buckwheat. It is endemic to Mendocino County, California, where it is known from only five occurrences on Red Mountain near Leggett. It grows in woodland habitat on serpentine soils.
Eriogonum kennedyi is a species of wild buckwheat known by the common name Kennedy's buckwheat.
Lupinus formosus, the summer lupine or western lupine, is a species of flowering plant in the legume family, Fabaceae. It is native to California and Oregon in the United States.
Callophrys dumetorum, the coastal green hairstreak, bramble green hairstreak, or bluish green hairstreak, is a butterfly of the family Lycaenidae. It is found in the United States in coastal California and rarely in inland California. Subspecies C. d. oregonensis is known as the Oregon green hairstreak.
Callophrys sheridanii, the Sheridan's hairstreak and Sheridan's green hairstreak, is a butterfly in the family Lycaenidae. It is found in North America along the south coast of British Columbia and parts of Nevada, Arizona, Saskatchewan, North Dakota, and New Mexico. In 2009, this species was adopted as the U.S. state butterfly for Wyoming.
Eriogonum niveum is a species of flowering plant in the buckwheat family known by the common name snow buckwheat. It is native to the Pacific Northwest of North America, where it occurs in British Columbia, Washington, Oregon, and Idaho. It flowers late in the summer.
Acanthoscyphus is a monotypic genus in the family Polygonaceae that contains the single species Acanthoscyphus parishii, which is sometimes called Parish's oxytheca. This species is native and endemic to southern California.
