Halogeton is a plant genus of the family Amaranthaceae. The genus name, Halogeton, derives from the Greek words for "salt" and for "neighbor."[1]
Description
[edit]The genus Halogeton includes both annual and perennial species. The leaves are fleshy cylindrical, terminating in a persistent or caducous bristle. There are three to several flowers in the axil of each floral leaf. The perianth segments are membranous. The stamens are fixed on a papillose staminodial disk. In fruit, the tepals develop five wings.
Distribution and habitat
[edit]The annual species grow in temperate salines and ruderal places, while the perennials are found in warm and hot deserts. They are tolerant of fairly saline soils.
Uses
[edit]Halogeton sativus was cultivated for the enormous 18th Century barilla industry in Spain that produced soda ash. The species was considered to be a "saltwort" plant.
Weeds
[edit]Halogeton glomeratus is considered a noxious weed in most regions of the United States;[2] a particular difficulty with H. glomeratus is that it is poisonous to sheep, and possibly to cattle, due to the high concentration of sodium oxalate in the dry plant.[3] The common names for H. glomeratus include halogeton (the same as the genus), barilla, and saltlover.[4]
Ecology
[edit]Halogeton species are used as food plants by the larvae of some Lepidoptera species including The Nutmeg and the Coleophora case-bearers C. klimeschiella and C. parthenica.
Systematics
[edit]The genus Halogeton was published in 1829 by Carl Anton von Meyer (in Ledeb., Icon. Pl. Fl. Ross. 1: 10), with the type species Halogeton glomeratus (M. Bieb.) C.A.Mey. Synonyms are Agathophora (Fenzl) Bunge and Micropeplis Bunge. The genus includes about 5 species:
- Halogeton alopecuroides (Delile) Moq.
- Halogeton arachnoideus Moq.
- Halogeton glomeratus (M. Bieb.) C. A. Mey.
- Halogeton sativus (L.) Moq., Synonym Salsola sativa L.
- Halogeton tibeticus Bunge (Bunge 1862; Botschantzev 1977).
