unisexual

Common botanical term for a plant with either only one male or only one female organ in the flower bud. The term "secondary unisexual" means that the species is originally bisexual, but one sex is suppressed. It is therefore not a bisexual hermaphrodite flower, as is the rule among cultivated grape varieties. The cultivated unisexual specimens are so-called purely female grape varieties, which must be fertilised with pollen from other plants. They are mostly intended for table grape cultivation and only rarely for wine production. See also under vine systematics and grapevine.
