Mentha, also known as mint (from Greek μίνθα míntha, [2] Linear B mi-ta [3]), is a genus of flowering plants in the mint family, Lamiaceae. [4] It is estimated that 13 to 24 species exist, but the exact distinction between species is unclear. [5] [1] Hybridization occurs naturally where some species' ranges overlap. Many hybrids and ...
Dischidia is a genus of plants in the “dog-bane” family Apocynaceae, collectively known as the “milkweeds” (true perennial milkweeds in the Apocynaceae are found in the genus Asclepias). They are epiphytes , native to tropical areas of China , India as well as Bhutan ’s southern borders, wherever minimal frost occurs.
Common names include thorn apple, bitter apple, [1] bitterball [4] and bitter tomato [5] [6] It may be confused with the similar S. linnaeanum where their ranges overlap in Africa. In ancient India, Solanum incanum was domesticated into the eggplant , Solanum melongena .
Plants which do not flower every year can achieve varying degrees of synchrony. Resource consumption can dictate how frequently a dioecious or gynoecious plant flowers, as producing seeds is a significant resource investment. When a plant flowers asynchronously in a year in which few other individuals are flowering, it has few mating ...
Arbutus unedo and A. andrachne hybridise naturally where their ranges overlap; the hybrid has been named Arbutus × andrachnoides (syn. A. × hybrida, or A. andrachne × unedo), [10] inheriting traits of both parent species, though fruits are not usually borne freely, and as a hybrid is unlikely to breed true from seed. It is sold in California ...
The species can also be distinguished by habitat: where the ranges overlap, common hackberry occurs primarily in upland areas, whereas sugarberry occurs mainly in bottomland areas. [3] Sugarberry's range extends from the Southeastern United States west to Texas and south to northeastern Mexico. [2] It is also found on the island of Bermuda. [4]
Rhododendrons are extensively hybridized in cultivation, and natural hybrids often occur in areas where species ranges overlap. There are over 28,000 cultivars of Rhododendron in the International Rhododendron Registry held by the Royal Horticultural Society. Most have been bred for their flowers, but a few are of garden interest because of ...
On one extreme is allopatry, in which the overlap is zero (no gene flow), and on the other extreme is sympatry, in which the ranges overlap completely (maximal gene flow). The varying definitions of sympatric speciation fall generally into two categories: definitions based on biogeography, or on population genetics.
