Extriplex joaquinana is a species known by the common name San Joaquin saltbush. It was formerly included in genus Atriplex.
Distribution
[edit]It is endemic to California,[1][2] where it grows in alkaline soils in the Sacramento-San Joaquin River Delta and adjacent parts of the Central Valley and eastern Central Coast Ranges.
Description
[edit]This is an annual herb growing erect to a maximum height near one meter. The leaves are 1 to 7 centimeters in length, often scaly, green to gray-green in color, and oval to triangular in shape. The leaves are mostly located lower on the erect plant; those further up the stem are reduced in size. The inflorescences of male flowers are dense, heavy spikes, and the female flowers are held in smaller clusters.
Systematics
[edit]The first publication of this taxon was in 1904 by Aven Nelson as Atriplex joaquinana A.Nelson (in: Proceedings of the Biological Society of Washington 17(12): 99).[3] (It has sometimes been wrongly spelled Atriplex joaquiniana). In 2010, after phylogenetic research, Elizabeth H. Zacharias classified it in a new genus Extriplex, as Extriplex joaquinana (A.Nelson) E.H.Zacharias.[4] Extriplex joaquinana belongs to the tribe Atripliceae in the subfamily Chenopodioideae of Amaranthaceae.[4]
