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 ...
For example, Albinaria land snails on islands in the Mediterranean [1] and Batrachoseps salamanders from California [2] each include relatively dispersal-limited, and closely related, ecologically similar species often have minimal range overlap, a pattern consistent with allopatric, nonecological speciation.
The balm-of-Gilead (Populus × jackii), also known as P. × gileadensis, is the hybrid between P. balsamifera and the eastern cottonwood (P. deltoides), occurring occasionally where the two parental species' ranges overlap.
Marah species hybridize freely where ranges overlap and this, in addition to intra-species leaf and fruit variability, makes definite identification of specimens a particular challenge. A proper genetic analysis of Marah phylogeny has not yet been undertaken. The standard taxonomy has been based on morphological comparisons and geographic ...
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
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.
Quercus × rosacea (or Quercus rosacea) (or Devony Oak), is a naturally occurring hybrid species of oak native to Europe. They are the offspring of sessile oak, Quercus petraea, and common oak, Quercus robur, found where their ranges overlap.
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 ...
