adjective
anomalous
uh-NAH-muh-lus/əˈnɑːmələs/
Different from what is normal or expected.
One anomalous plant breaks the otherwise uniform pattern.

Etymology
The pieces mean “not even,” giving the image of unevenness or irregularity. Applied to a rule or pattern rather than a surface, this describes something that departs from what is normal or expected.
In context
