Definition

Noun: A bilocular capsule is a specific type of dry, dehiscent fruit that splits open at maturity. Its defining characteristic is that it is divided internally into two separate chambers or compartments, each containing seeds.

Usage

This term is used in botanical contexts to describe the structure of a seed pod or fruit from certain plants. It classifies the fruit based on its internal division.

Examples

• The fruit of the (bleeding heart) plant is a bilocular capsule.
• Upon examination, the botanist identified the specimen by its bilocular capsule.
• A bilocular capsule typically splits along seams (sutures) between the two locales to release its seeds.

Advanced Usage

In detailed botanical descriptions, the term specifies the ovary's structure from which the fruit developed. A bilocular capsule originates from a superior ovary with two fused carpels, forming two distinct locales.
