Atripliceae are a tribe of the subfamily Chenopodioideae belonging to the plant family Amaranthaceae. Atriplex is the largest genus of the family. Species of Atripiceae are ecologically important in steppe and semi-desert climates.[1]
Distribution
Most of the species are distributed in Africa, Australia, and North America, with some others spread out worldwide.[2]
Taxonomy
Traditional taxonomy of Atripliceae based on morphological features has been controversial.[1][2] Molecular studies have found that many genera are not true clades. One such study found that Atripliceae could be divided into two main clades, Archiatriplex, with a few, scattered species, and the larger Atriaplex clade, which is highly diverse and found around the world.[2]
Description
The fruits of species in the tribe have a membranous or sometimes succulent pericarp adhering to or loosely covering seeds. The dark seed coat varies from almost smooth to finely striate, rugulose, or pitted.
In monoecious (hermaphroditic) plants, flowers are dimorphic, bisexual or pistillate. Flowers are made up of spicately or paniculately arranged glomerules of blossoms.
