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. [1]

Description

The species in genus Halimione are annual or perennial herbs with silvery grey stems and leaves. Their stems grow prostrate, ascending or erect. The leaves are opposite in lower part and alternate in upper part of the plants. The leaf blade is oblong with entire margins. [2]

Plants are monoecious. The spicate inflorescences consist of inconspicuous flowers. Male flowers comprise 4-5 perianth segments and 4-5 stamens. Female flowers have 2 totally concrescent, three-lobed bracteoles which enclose the ovary, a perianth is missing. [2]

The pericarp is tightly adherent to the inner side of the bracteoles, and also tightly adherent to the seed. The seed is vertically orientated, with a thin, membraneous seed coat. It is anatomically different from Atriplex (which has a brownish, thick and hard seed coat). [2]

Halimione pedunculata and Halimione verrucifera have a chromosome number of 2n = 18, Halimione portulacoides 2n = 36. [3]

Systematics

The genus has been first described in 1822 as Halimus by Karl Friedrich Wallroth (in Schedulae Criticae, p. 117). But this name was illegitimate, as there existed already Halimus Patrick Browne (1756) in family Portulacaceae. Paul Aellen  [ de; es; pt ] replaced this illegitimate name by the valid name Halimione in 1938 (in: Verhandlungen der Naturforschenden Gesellschaft in Basel, 49, p. 121). Type species is Halimione pedunculata (L.) Aellen. [3]

During the following years, Halimione has sometimes been included in Atriplex . Molecular phylogenetic research by Kadereit et al. (2010) revealed that Halimione is a sister genus of Atriplex. [2] A 2019 study reached the same conclusion. [4]

Halimione comprises 3 species in 2 sections: [2]

Distribution

Halimione is distributed in Europe, North Africa, and Asia, ranging from Southwest Asia, and Central Asia to China (Xinjiang). [5] [6]

<span class="mw-page-title-main">Chenopodioideae</span> Subfamily of flowering plants

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 the family Chenopodiaceae, or goosefoot family, in the Cronquist system.

<i>Atriplex</i> Genus of flowering plant

Atriplex is a plant genus of about 250 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.
