HETEROSTYLY AND SELF. “The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility, termed heteromorphic self-incompatibility, that is, the pollen from a flower on one morph cannot fertilize another flower of the same morph.” https://en.m.wikipedia.org/wiki/Heterostyly View in LinkedIn

“HERKOGAMY is a common strategy employed by hermaphroditic angiosperms to reduce sexual interference between male (anthers) and female (stigma) function. Herkogamy differs from other such strategies (e.g. dichogamy) by supplying a spatial separation of the anthers and stigma.” https://lnkd.in/dAT6_q2 View in LinkedIn

HETEROSTYLY DEFINED. “Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous.” https://lnkd.in/dBgeGam View in LinkedIn

POLYMORPHISM #3. "Heterostyly and dioecy are the best-known sexual polymorphism of this type, with heterostylous populations usually composed of two (distyly) or three (tristyly) style morphs, and dioecious populations composed of female and male plants." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

POLYMORPHISM #2. "A second class of polymorphism involves species in which mating types are morphologically distinct and field observations can reveal their number and frequency in populations." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

POLYMORPHISM #1. "The most common is homomorphic self-incompatibility, in which the mating types are morphologically indistinguishable and numerous." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

TRANSGRESSIVE CHARACTERISTICS. “Studies of quantitative traits in segregating hybrid populations sometimes report the presence of phenotypes that are extreme relative to those of either parental line. The generation of these extreme phenotypes is referred to as transgressive segregation, and this is a major mechanism by which extreme or novel adaptations observed in new hybrid ecotypes or species are thought to arise.” https://lnkd.in/d4xXNs5 View in LinkedIn

UNEVEN PLANT HYBRIDIZATION. "There is strong evidence that hybridization does not occur uniformly across all plant families, and hence spontaneous hybridization seems to be more prevalent in certain families and genera. A group with high levels of natural hybridization is Rhododendron. The genus has more than 1000 species, many of which are interfertile." https://lnkd.in/dK-A3iM View in LinkedIn

SPECIES NAMING REVERSALS. "Over time there have been many examples across different genera and families, where a plant described as a new species has been subsequently proven to be a hybrid." https://lnkd.in/dK-A3iM View in LinkedIn
