Which plant forms occur in the family Loganiaceae?

The family Loganiaceae, which belongs to the order Gentianales, consists of plants that primarily take the form of woody vines, shrubs, or trees. While some sources also categorize the family as including herbs, the order Gentianales as a whole is characterized more by its woody members—trees, shrubs, and vines—than by annual or perennial herbs.1234

These plants are native primarily to tropical regions of the world. They are distinguished by their simple, opposite leaves, which typically feature stipules or interpetiolar lines, and the presence of colleters (multicellular glands) at the base of the leaves. Their fruits are diverse, ranging from capsules to fleshy drupes.12
