Gentianales
Great yellow gentian (Gentiana lutea) plants in bloom.
In the Gentianales order of flowering plants, the leaves are typically arranged in an opposite or whorled pattern, meaning there are two or more leaves per node. These leaves are simple and are often accompanied by stipules, which are small, leaflike appendages located at the base of the leaf stalks.1
