The condition of Polyadelphous can be found in

The correct option is Rutaceae.

Understanding Polyadelphous Stamens:
In angiosperm flowers, the androecium consists of male reproductive units called stamens. A stamen typically has a filament and an anther. Based on the fusion of these stamens, various cohesion patterns are observed:
1. Adelphy: This is the condition where the filaments of stamens are fused together into one or more bundles, but the anthers remain free.
2. Polyadelphous: When the filaments are fused to form several distinct bundles or groups, the condition is termed polyadelphous. Examples of plants exhibiting this condition include Citrus (lemon, orange) and Bombax (silk cotton).

Analyzing the Options:
- Rutaceae: The citrus family (Rutaceae), which includes oranges and lemons, typically exhibits the polyadelphous condition where filaments are united into multiple bundles.
- Leguminosae (Fabaceae): This family generally shows a diadelphous condition (filaments fused into two groups, often written as 9 + 1 in pea plants).
- Compositae (Asteraceae): This family exhibits a syngenesious condition, where the anthers are fused into a tube around the style, but the filaments remain free.
- Liliaceae: This family typically has free stamens (polyandrous condition) and they are often epiphyllous (attached to perianth lobes).

Therefore, the polyadelphous condition is a characteristic feature found in members of the family Rutaceae.
