Extriplex joaquinana is a species known by the common name San Joaquin saltbush. It was formerly included in genus Atriplex .
It is endemic to California, [1] [2] where it grows in alkaline soils in the Sacramento-San Joaquin River Delta and adjacent parts of the Central Valley and eastern Central Coast Ranges.
This is an annual herb growing erect to a maximum height near one meter. The leaves are 1 to 7 centimeters in length, often scaly, green to gray-green in color, and oval to triangular in shape. The leaves are mostly located lower on the erect plant; those further up the stem are reduced in size. The inflorescences of male flowers are dense, heavy spikes, and the female flowers are held in smaller clusters.
The first publication of this taxon was in 1904 by Aven Nelson as Atriplex joaquinana A.Nelson (in: Proceedings of the Biological Society of Washington 17(12): 99). [3] (It has sometimes been wrongly spelled Atriplex joaquiniana). In 2010, after phylogenetic research, Elizabeth H. Zacharias classified it in a new genus Extriplex , as Extriplex joaquinana (A.Nelson) E.H.Zacharias. [4] Extriplex joaquinana belongs to the tribe Atripliceae in the subfamily Chenopodioideae of Amaranthaceae. [4]
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included - together with other subfamilies - in family Chenopodiaceae in the Cronquist system. Food species comprise Spinach, Good King Henry, several Chenopodium species, Orache, and Epazote. The name is Greek for goosefoot, the common name of a genus of plants having small greenish flowers.
Atriplex is a plant genus of 250–300 species, known by the common names of saltbush and orache. It belongs to the subfamily Chenopodioideae of the family Amaranthaceae s.l.. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination.
Halimione portulacoides or sea purslane (2n=36) is a small greyish-green shrub widely distributed in temperate Eurasia and parts of Africa.
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them.
Atriplex cinerea, commonly known as grey saltbush, coast saltbush, barilla or truganini, is a plant species in the family Amaranthaceae. It occurs in sheltered coastal areas and around salt lakes in the Australian states of Western Australia, South Australia, Tasmania, Victoria and New South Wales.
Grayia is a genus of plants in the subfamily Chenopodioideae of the family Amaranthaceae. Common names are siltbush and hopsage. The four shrubby species occur in arid and semiarid regions of western North America:
Grayia spinosa is a species of the genus Grayia in the subfamily Chenopodioideae of the flowering plant family Amaranthaceae, which is known by the common names hop sage and spiny hop sage. It is widely distributed across the Western United States, where it grows in a number of desert and mountain habitats.
Atriplex hortensis, known as garden orache, red orache or simply orache, mountain spinach, French spinach, or arrach, is a species of plant in the amaranth family used as a leaf vegetable that was common before spinach and still grown as a warm-weather alternative to that crop. It is Eurasian, native to Asia and Europe, and widely naturalized in Canada, the United States, Australia, and New Zealand.
Krascheninnikovia is a genus of flowering plants in the subfamily Chenopodioideae of the family Amaranthaceae known as winterfat, so-called because it is a nutritious livestock forage. They are known from Eurasia and western North America. These are hairy perennials or small shrubs which may be monoecious or dioecious. They bear spike inflorescences of woolly flowers.
Extriplex californica is a plant species known by the common name California saltbush or California orache. Formerly, it was included in genus Atriplex. It is native to coastal California and Baja California, where it grows in areas with saline soils, such as beaches and salt marshes.
Atriplex cordulata is a species of saltbush known by the common names heartscale and heart-leaf orache. It is endemic to the Central Valley and its San Joaquin Valley of California, where it grows in areas of saline and alkaline soils.
Atriplex coronata is a species of saltbush known by the common name crownscale. It is endemic to California.
Atriplex tularensis is an extremely rare species of saltbush known by the common names Bakersfield smallscale, Tulare saltbush, and Tulare orach.
Halimione is a plant genus from the subfamily Chenopodioideae of the family Amaranthaceae. It is a sister genus of Atriplex and is included in that genus by Plants of the World Online.
Extriplex is a plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. It has been described in 2010 and comprises two species, that were formerly included in genus Atriplex. They are restricted to the California Floristic Province.
Stutzia is a plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. It was described in 2010, replacing the illegitimate name Endolepis. It comprises two species, that have also been included in the genus Atriplex.
Proatriplex is a monotypic plant genus in the subfamily Chenopodioideae of the family Amaranthaceae, with the only species Proatriplex pleiantha. It is known by the common names four-corners orach and Mancos shadscale. It occurs in the Navajo Basin of Arizona, Colorado, New Mexico, and Utah.
Atripliceae are a tribe of the subfamily Chenopodioideae belonging to the plant family Amaranthaceae. Atriplex is the largest genus of the family. Species of Atripiceae are ecologically important in steppe and semi-desert climates.
Atriplex holocarpa is a low-growing species of Atriplex (saltbush) found throughout arid regions of Australia. A. holocarpa is commonly known as pop saltbush, because its carpals pop when stepped upon.
Exomis is a genus of flowering plants belonging to the family Amaranthaceae. It just contains one species, Exomis microphylla(Thunb.) Aellen It is also in the Chenopodioideae subfamily.
