The evolutionary breakdown of distyly inLinum tenuifolium (Linaceae)
Plant Systematics and Evolution, 1985Distyly inLinum tenuifolium L. is associated with a high degree of self-incompatibility. Breakdown in this system has occurred without the morphological rearrangement expected as the result of cross-over within the distyly supergene. Pollen-flow in both distylous and monomorphic populations is leptokurtic.

Distyly and heteromorphic incompatibility in oceanic island species ofErythroxylum (Erythroxylaceae)
Plant Systematics and Evolution, 1998Surveys of oceanic island floras have shown that heterostyly is usually absent in such regions, probably because this floral polymorphism is often associated with a self-incompatibility system. In this context we describe the floral biology of three species ofErythroxylum on La Reunion island and examine the compatibility relationships of one of these ...

Within the ongoing trend of rapid climate changes there is an urgent need to assess the vulnerability of the endangered species for evaluating their conservation status and planning effective actions. Primula palinuri Petagna is a relict chasmophyte classified as Vulnerable due to its decreasing populations.

Distyly and Population Structure of Neanotis montholonii (Hook F.) W.H. (Rubiaceae)
Ls- International Journal Of Life Sciences, 2021AbstractDistyly in Neanotis monthlonii (Hook F.) W.H. (Rubiaceae) is described for the time. The heterostyly with Pin and thrum forms is described and the natural populations studied show balanced polymorphism, hence isopleths. Distyly is reciprocal mechanical arrangement of style and stamen height accompanied by an array of contrasting differences in ...

Plant Systematics and Evolution, 2008
Distyly typically involves reciprocal polymorphism in stamen and style lengths and a set of associated polymorphisms of pollen and stigma characters. This flower polymorphism has been regarded as a strategy to reduce the likelihood of self- and intramorph pollination and to promote legitimate intermorph pollination.

THE PROBABLE GENETICS OF DISTYLY IN GELSEMIUM SEMPERVIRENS (LOGANIACEAE)
Canadian Journal of Genetics and Cytology, 1980A crossing program with Gelsemium sempervirens (L.) Javme Saint-Hilaire was used to obtain progenies for determination of the genetic basis of distyly in this species. The results suggest that in G. sempervirens, pins are homozygous recessive (ss) and thrums are heterozygous (Ss) with thrum dominant over pin.

Distyly, pollen flow and seed set in Menyanthes trifoliata (Menyanthaceae)
2010The influence of variation in style length on pollen flow and seed set was examined in six populations of Menyanthes trifoliata in southwestern British Columbia to evaluate Ganders' hypothesis that morphological distyly increases the fecundity of a diallelic self-incompatible plant.
