Corispermoideae

Gray bugs Same ( Corispermum marschallii )

Corispermeae is the only tribe of the subfamily Corispermoideae within the family of Amaranthaceae ( Amaranthaceae ). Previously they were made ​​the goosefoot family ( Chenopodiaceae ).

Description

The species of the subfamily Corispermoideae are annuals. Your best alternate arranged leaves are sessile or leaf stalk -like narrowed area and skleromorph. Young plant parts have a characteristic pubescence of branched trichomes (except for Anthochlamys ).

The aged men inflorescences or simple, compact (sometimes convoluted ) part inflorescences have no bracts ( Brakteolen ). The perianth consists of one to five white, membranous bloom cladding (missing in some Corispermum species) that have no vascular bundles and not outlast the flowering period ( anthesis ). The pollen grains of Agriophyllum and Corispermum are from " Chenopodium - type " of Anthochlamys of its own " Anthochlamys type ".

The fruits have supporting tissue of Makrosklereiden. The seeds contain a vertical embryo and abundant Perisperm.

Photosynthetic

All previously studied species show a leaf anatomy without crown layer ( Corispermum type) and C3 plants.

Dissemination

The subfamily Corispermoideae is widespread in Eurasia and North America.

System

The Tribe Corispermeae in 1840 erected by Christian Horace Alfred Moquin - Tandon Bénédict in Chenopodearum Monographica Enumeratio, Loss, Paris, pp. 182. 1934, Oskar Eberhard Ulbrich the subfamily Corispermoideae in Chenopodiaceae, pp. 379-584 in Adolf Engler and Karl Anton Eugen Prantl (Editor ): The natural plant families, Volume 16 c, Engelmann, Leipzig on.

Phylogenetic analyzes confirm the monophyly of the subfamily Corispermoideae.

The subfamily contains only a Corispermoideae Tribus:

• Tribus Corispermeae: With three genera and about 70 species: Agriophyllum M.Bieb. With about six species in the arid regions of Central Asia and the Middle East.
• Anthochlamys Fenzl. Using two species in arid regions of Asia.
• Bugs seeds ( Corispermum L.): With at least 65 species in Eurasia and North America.
