Halimione

Purslane wedge reporting ( Halimione portulacoides )

The wedge Report ( Halimione ), also called salt Log, are a genus of flowering plants in the family Amaranthaceae ( Amaranthaceae ).

Description

Vegetative characteristics

The wedge Report are annual or perennial herbaceous plants. The prostrate, ascending or erect stem and the leaves are silvery- gray. The leaves are opposite, further arranged alternate up the stem. Leaf blades are oblong shaped and entire.

Inflorescences and flowers

The inconspicuous flowers are in aged men inflorescences. Wedge Sign species are monoecious getrenntgeschlechtig ( monoecious ). The male flowers have no bracteoles; they contain four or five bracts ( tepals ) and four to five stamens. The female flowers are surrounded by two linked up top, three-lobed continue reading. Bracts absent the female flowers, they contain only one ovary.

Fruit and seeds

It is characteristic for the genus of the wedge Report that the pericarp adheres closely to the Next page. The seed stands upright, its root is in the fruit upward. The seed coat is thin, membranous and transparent, and also differs anatomically Report of the genus ( Atriplex ), the seed coat is hard, thick and brown.

Chromosome number

The chromosome number is 2n = 18 verrucifera at Halimione pedunculata and Halimione and 2n = 36 in Halimione portulacoides.

Occurrence

The wedge Report are prevalent in Europe, North Africa and Asia. Your area extends east from Southwest Asia via Central Asia to the Chinese province of Xinjiang.

System

The genus belongs to the tribe Halimione Atripliceae in the subfamily Chenopodioideae within the family of Amaranthaceae ( Amaranthaceae ). In this family, the Goosefoot family ( Chenopodiaceae ) are now included.

The fact that the three types that are now considered the wedge Report ( Halimione ), are from the Report ( Atriplex ) differ, was discovered in 1822. This year, Karl Friedrich Wallroth summarized these species in Schedulae Criticae, p 117 together under the name halimus. This generic name was already taken, however, and thus illegitimate because already in 1756 Patrick Browne had erected the genus halimus within the Portulakgewächse ( Portulacaceae ). That is why Paul gave Aellen 1938 this genus the valid name Halimione, in negotiations the Natural History Society in Basel, 49, p.121. The type species is Halimione pedunculata (L.) Aellen.

In the following years this species was often reunited with Atriplex. Phylogenetic analyzes of Kadereit et al. (2010) revealed, however, that Halimione not belong in the genus Atriplex, but as a separate genus endures.

A synonym of Halimione Aellen is halimus Wallr. ( nomen illeg. ).

The genus includes three species and is divided into two sections:

• Halimione section Halimione: With a kind: Stalked wedge reporting ( Halimione pedunculata (L.) Aellen Syn: Atriplex pedunculata L.): It is native halophytes corridors of Western Europe to Western Asia and the Black Sea.

• Purslane wedge reporting ( Halimione portulacoides (L.) Aellen Syn: Atriplex portulacoides L.): it is, and the Mediterranean coast of North Africa spread to the sea coasts of western and southern Europe to western Asia.
• Halimione verrucifera ( M.Bieb. ) Aellen ( Syn: Atriplex verrucifera M.Bieb. ): It comes from Eastern and South-Eastern Europe (Romania, Ukraine) by Southwest and Central Asia to the Chinese province of Xinjiang ago. Their habitat are saline wasteland, dune valleys and roadsides.
