Description:

Atriplex coronata var. notatior is a variation of the Crownscale that can be found in various wetlands and grasslands across San Jacinto Valley, CA. A. c. var. notatior is a dynamic species that flourishes after the rainy season when there is local, large-scale flooding. This annual herb also utilizes these flooded conditions to distribute its seed by ferrying its fruit (which are buoyant) across the flooded waterways. Whether in or out of the rainy season, the seeds can stay viable for up to five years. Across California however, wetland habitats are being fragmented by ongoing urbanization and agriculture.
