Teucrium is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.
Teucrium scorodonia, common name the woodland germander or wood sage, is a perennial herb belonging to the genus Teucrium of the family Lamiaceae. It is native to Western Europe and Tunisia, cultivated in many places as an ornamental plant in gardens, and naturalized in several regions.
Gynodioecy is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate stage between hermaphroditism and dioecy. Gynodioecy is the opposite of androdioecy, which is a breeding system consisting of male and hermaphroditic plants in a population. Gynodioecy occurs as a result of a genetic mutation that inhibits a hermaphroditic plant from producing pollen, while keeping the female reproductive parts intact. Gynodioecy is extremely rare, with fewer than 1% of angiosperm species exhibiting the breeding system. Some notable taxa that exhibit a gynodioecious mating system include Beta vulgaris, Lobelia siphilitica, Silene, and Lamiaceae.
