Atriplex Linnaeus. Common name: Orach.
A genus of about 300 species, herbs and shrubs, of cosmopolitan distribution.
Key advice:A number of idiosyncratic characters are used in the identification of the species of Atriplex. Many important characters are associated with the mature fruits. The fruit is closely invested by 2 bracteoles, which are variously shaped and ornamented. Mature seeds are dimorphic in most of our species, with larger brown seeds and smaller black seeds. The radicle of the seeds is variously apical, lateral, or basal (which can be seen by observing the seed through the clarified bracteoles or with strong transmitted light).

- Please include your name and if possible, email in case when need to clarify what you wrote.
- If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
- Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
- Please do not send us feedback about unkeyed species as this work is ongoing.
- Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
