Other info. - This species is found throughout most of Missouri but seems to be absent from the north-central portion of the state. This species is easy to ID because of its toothed leaves. No other wild species of Croton in Missouri has toothed leaves. The species epithet comes from the fact that the leaves typically have two glands at the base of each leaf blade.
