👉 Campogramma is a term used in botany that describes the structure of plants, specifically those with a single stem and no leaves or stems. It's often associated with gymnosperms, which are the flowering plants, as they have only one set of flowers per plant. Campogrammas are typically characterized by their single stem, which can be either a cylindrical shape or a more elongated form, with a central vein that leads to a vascular network, called a hypanthium.
