Halimione portulacoides the sea shores of western and southern Europe, and from the Mediterranean Sea to western Asia. Copeland Islands (Co. Down). Botanical synonyms include "Atriplex portulacoides" L. and "Obione portulacoides" (L.) Moq. Recent phylogenetic research revealed, that "Halimione" is a distinct genus and can not be included in "Atriplex". Halimione portulacoides Halimione portulacoides or sea purslane (2n=36) is a small greyish-green shrub widely distributed in temperate Eurasia and parts of Africa. A halophyte, it is found in salt marshes and coastal dunes, and is usually flooded at high tide. The plant grows to 75 cm. It is evergreen, and in northern
African admixture in Europe Europe may have a common origin in Asia (e.g. Y haplogroups R1, and some paternal haplogroup T and U subclades). One subclade of haplogroup U, namely U6a1, is known to have expanded from northern and eastern Africa back into Europe even though haplogroup U6 is considered to have originated in the Middle East. Other lineages are known to have moved from Europe directly into Africa, for example mitochondrial haplogroups H1 and H3. Such bidirectional migrations between Africa and Eurasia complicate the task of defining admixture. One proposed example of Holocene gene flow from Africa to Europe, via the Middle East,
