#anthocarp

• Acanthocarpous — A plant morphological term used as an adjective to describe a plant, variety, or structure whose fruit is covered with spines, thorns, rigid spikes, or sharp outgrowths. This anatomical adaptation of the pericarp serves the primary purpose of protecting developing seeds against predators and facilitating zoochory, allowing the fruit to cling to animal fur for dispersal (as seen in the horse chestnut or certain Xanthium species).
• Anthocarp — A type of false fruit or complex plant structure where the true fruit (usually an achene) remains tightly enveloped and protected by the persistent, altered, or lignified base of the perianth or floral calyx (characteristic of plants in the Nyctaginaceae family, such as the four o'clock flower). This structural formation plays a vital role in seed dissemination and protection against environmental factors.
