Definition of heterostyly in English:

heterostyly

nounˈhɛtərə(ʊ)ˌstʌɪliˈhedərəˌstīlē

mass nounBotany

The condition (e.g. in primroses) of having styles of different lengths relative to the stamens in the flowers of different individual plants, to reduce self-fertilization.
〔植〕花柱异长（如樱草花）
Example sentencesExamples
- Tylosema, in the tribe Cercideae, has been little investigated but heterostyly, unknown elsewhere in the Fabaceae, has been reported in all four species of the genus.
- One of the earliest hypothesized and widely known cases of a coadapted gene complex in plants is that of heterostyly.
- Although gender specialization is not a regular feature of heterostyly, reproductive differences between morphs has been reported for most studied distylous species.
- Flowering plants have several mechanisms that have evolved to prevent self-fertilization, e.g. self-incompatibility systems, heterostyly and dichogamy.
- Darwin's correlation between the phenotype and the cross-compatibility of the two forms of flower provided the foundation for subsequent analyses of heterostyly in Primula.

Both F. jinshaense and F. gilesii are self-incompatible with heterostylous flowers and are diploid.
Example sentencesExamples

- Pentanisia appears to exhibit dimorphisms typically associated with heterostylous plants.
- Field observations confirmed that the species is heterostylous with the pistil and anthers exhibiting reciprocal heights in the two morphs, although pollen size and sculpturing do not vary.
