PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.

Look-alike warning

Could be mistaken for Other plants with a similar name or look. To tell them apart: Match on the scientific name, Quercus potosina Trel. (author as printed in Flora del Bajio and eFloraMex; Kew WCVP prints the author slightly differently but accepts the same name), not on the common name.. Do not mix up with Quercus pringlei, a 1-2 m shrub described right after it in Flora del Bajio.
