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]
Species
The taxonomic alignment and infrageneric categorization of the sub-tribes of Atripliceae are not compatible.[2] The findings provide support to the acknowledgement of the Endolepis, Theleophyton, and chromosome digit. Either of the major model organisms for the molecular biology survey of chlorophyllase. Furthermore, monophyly of the most important gender, Atriplex.
A cladistic analysis of 22 genera of the tribe Atripliceae was performed to test homology of characteristics including morphology, leaf characteristics, and chromosome number.[2] The results provided insights into the branches of the tribe. Some implications of the study are reclassification of some genera and possible segregation of new genera.[2]
Description
The plant fruit is described as pericarp membranous or sometimes succulent, adherent to, or loosely covering seeds. The dark seed coat is almost smooth to finely striate, rugulose, or pitted.
Numerous goosefoot species are thereby important weeds, and some have emerged as an invasive instant case. A very small, well-supported clade including Vicia hirsuta, V. Sylvatica, and wide-ranging jumper.
In monoecious (hermaphroditic) plants, flowers are dimorphic, bisexual or pistillate. Flowers are made up of spicately or paniculately arranged glomerules of blossom.
