About Matscale (Atriplex watsonii) Atriplex watsonii is a species of saltbush known by the common name Watson's saltbush, or Watson's orach. It is native to the coastline of California and Baja California, where it grows in areas with saline soils, such as salt marshes and beach scrub, with other salt-tolerant plants such as saltgrass. This is a gray-green to whitish perennial herb with tangled slender stems under a meter in length. It grows in mats up to 3 meters wide. The thick, fleshy, crusty leaves are up to 2.5 centimeters long and generally oval in shape. The plant is dioecious, with individuals bearing either male or female flowers. The male flowers grow in clusters or long spikes, and the female flowers can be found in small clusters in the leaf axils.
