DIANDRIA (from dis, twice, and man, a man), the name of the second class in Linnaeus's sexual system, consisting of hermaphrodite plants: which, as the name imports, have flowers with two stamina or male organs.
The orders in this class are three, derived from the number of styles or female parts. Most plants with two stamina have one style; as jessamine, lilac, privet, veronica, and bastard alaternus: vernal grass has two styles; pepper, three.
