Etymology:

The genus Atriplex is from ancient Latin and was applied to the edible oraches (plants in the Chenopodiaceae family). The common name for the genus, "Saltbush" is derived from the plants ability to retain salt in their leaves making them able to thrive in saline soil or alkaline soils.

The species epithet hymenelytra makes reference to Hymen, a mid 16th century late Latin from Greek humèn meaning "membrane"; possibly a reference to the paired fruiting bracteoles surrounding the seeds
