<start_of_turn>model
Axile placentation is a type of arrangement of ovules within an ovary in flowering plants (angiosperms). It is characterized by the presence of a central column called the "axis" or "placenta" in the ovary, to which the ovules are attached. The ovules are attached along the central axis, and they can be found in two or more rows. Axile placentation is commonly observed in the following plant families:

1. Solanaceae: This family includes plants like tomatoes, potatoes, and bell peppers. In the Solanaceae family, axile placentation is frequently observed.

2. Fabaceae (Leguminosae): This is the pea family, which includes plants like peas, beans, and lentils. Axile placentation can be found in the ovary of many species within this family.

3. Brassicaceae (Cruciferae): This is the mustard family, which includes plants like mustard, broccoli, and cabbage. Some members of this family exhibit axile placentation.

4. Euphorbiaceae: The spurge family, which includes plants like poinsettias and castor beans, also often shows axile placentation.

5. Lamiaceae (Labiatae): This family includes plants like mint and basil. Axile placentation can be found in the ovary of certain species in this family.<end_of_turn><eos>
