Pseudo-carp is a botanical term that refers to the characteristic fruit structure of certain flowering plants. These fruits are formed from the fusion of several individual flowers that develop into a single unit. There are several synonyms for pseudo-carp, including syncarp, composite fruit, and aggregated fruit. The term syncarp emphasizes the fusion aspect of the fruit, while composite fruit highlights the idea that it is made up of multiple parts. Aggregated fruit is a more general term that encompasses any fruit formed by the clustering of several individual flower structures. Understanding these synonyms can help botanists and horticulturists communicate more effectively when discussing this unique type of fruit.
