It is a sister genus of ''Atriplex'' and has sometimes been included in this genus. == 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.〔 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.〔 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).〔 ''Halimione pedunculata'' and ''Halimione verrucifera'' have a chromosome number of 2n = 18, ''Halimione portulacoides'' 2n = 36.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Halimione」の詳細全文を読む スポンサード リンク
