Dioscorea villosa. Dioscorea villosa flower petal color is commonly known to be green to brown, or white. Lengths of the flower petals range from 0.5 to 2 mm (1 ⁄ 32 to 3 ⁄ 32 in). The flowers tend to grow out of the axil; this is the point at which a branch or leaf attaches to the main stem.
Male Dioscorea batatas (D. polystachya) in Hooker's A General System of Botany 1873 While Lindley did not use the term "Dioscoreales", he placed the family Dioscoraceae together with four other families in what he referred to as an Alliance (the equivalent of the modern Order) called Dictyogens.
Furthermore, Dioscorea is a twiner, this means that the plant undergoes circumnutation which is a helical movement that allows stems to wrap around objects. In order for this mechanism to take place, endodermal cells, plasmodesmata, the plasma membrane, epidermal cells, calcium, potassium, chloride, and proton pumps are required. [ 16 ]
Yam is the common name for some plant species in the genus Dioscorea (family Dioscoreaceae) that form edible tubers (some other species in the genus being toxic). Yams are perennial herbaceous vines native to Africa, Asia, and the Americas and cultivated for the consumption of their starchy tubers in many temperate and tropical regions.

One study showed that the Dioscorea villosa contains 3.5% diosgenin. [149] Dioscorea polygonoides has been found to contain 2.64% diosgenin as shown by gas chromatography-mass spectrometry. [150] Many of the Dioscorea species that originate from the yam family grow in countries that have tropical and subtropical climates. [151]
