Definition

1. Noun:
   • A pistil composed of two or more fused carpels: In botany, a "compound pistil" is the female reproductive organ of a flower that is formed from the fusion of two or more individual carpels (the basic units of the pistil). It appears as a single structure but contains multiple fused ovaries, styles, or stigmas.

Usage Examples

• Noun:
  • The lily flower has a compound pistil. (The lily's female reproductive structure is made from several fused carpels.)
  • Botanists identified the plant by examining its compound pistil. (Scientists classified the plant by studying its pistil, which consisted of multiple united carpels.)

Advanced Usage

• "To have a compound pistil": Describes a characteristic of a plant species.
  • Most species in the rose family have a compound pistil. (It is typical for plants in this family to possess a pistil formed from fused carpels.)

Variants and Related Words

• Simple pistil (n): A pistil consisting of a single, unfused carpel.
  • A pea flower has a simple pistil.
• Carpel (n): The fundamental female reproductive unit of a flower, which can be solitary or part of a compound structure.

Synonyms

• Fused pistil: A pistil where carpels are joined together.

Related Phrases

• Compound ovary: Often used interchangeably when referring to the fused ovarian part of a compound pistil.

Notes on Meaning

• The term is strictly botanical. It describes a specific morphological structure and is not used in general language.
• A compound pistil is contrasted with a simple pistil. The number of fused carpels can often be inferred by counting the number of styles, stigmas, or locules (chambers) in the ovary.
