A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit and indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away than regular seeds from the parent tree: Some species that normally produce paired samaras, such as Acer pseudoplatanus, also produce them in groups of 3 or 4. * Unusual group of three samaras of sycamore maple (Acer pseudoplatanus. They are normally paired) * Seeds of the tropical ash (Fraxinus uhdei) * *
