Definition

Noun: 1. A type of dry, indehiscent fruit with a wing-like structure: A samara is a simple, dry fruit that does not split open (indehiscent) at maturity. Its defining characteristic is a flattened, papery wing that develops from the ovary wall. This wing aids in wind dispersal, allowing the seed to travel away from the parent plant.

Examples of Usage

• The samaras of the maple tree spin like helicopters as they fall.
• You can identify an ash tree by its clusters of paddle-shaped samaras.
• Botanists study the samara as an excellent example of adaptation for seed dispersal.

Advanced Usage

• Botanical Terminology: In technical botanical descriptions, a samara may be classified as a subtype of an achene (a small, dry, one-seeded fruit) that possesses a wing. A samara can contain one seed (e.g., ash, elm) or two seeds (e.g., maple).

Variants and Related Words

• Key: The samara is the entire fruit structure. The seed is contained within the swollen part of the fruit.
• Related Botanical Terms:
  • Achene: A small, dry, one-seeded fruit that does not open to release the seed (e.g., sunflower "seed"). A samara is a winged achene.
  • Nut: A hard, one-seeded fruit that does not split open, but typically lacks a large, papery wing (e.g., acorn, hazelnut).
  • Indehiscent: A term for fruits that do not split open along a seam at maturity.

Synonyms

• Key fruit
• Winged achene
• Whirlybird (informal, specifically for maple samaras due to their spinning motion)
