Anomalous means different, for example, some monocots can experience secondary growth, but they are not. What they are actually doing is the parenchyma tissues either divide or enlarge, hence increasing the girth of the stem.
Monocots will never have secondary vascular bundles
Some monocots is under anomalous secondary growth
Eudicots undergo both primary and secondary. Eudicots **never undergo anomalous secondary grwoth**.
