THE GENETICAL ARCHITECTURE OF HETEROSTYLY IN PRIMULA SINENSIS [PDF]

Evolution, 1950
Flowering plants show a variety of mechanisms which encourage, or even ensure, the setting of seed by crossrather than by self-pollination. Heterostyly is such an outbreeding device and it is widespread in its occurrence. Heterostyled species may be classified into two groups, the distylic and tristylic, the former being the commoner type.

Breeding biology and distyly in Palicourea rigida H. B. & K. (Rubiaceae) in the Cerrados of Central Brazil Biologia reprodutiva e distilia em Palicourea rigida H. B. & K. (Rubiaceae) em Cerrados do Brasil Central

Acta Botânica Brasílica, 2010
Distyly is a floral polymorphism more common among the Rubiaceae than in any other angiosperm group. Palicourea rigida is a typically distylous species of the Rubiaceae widely distributed in the Brazilian Cerrados.

Genome size, morphological and palynological variations, and heterostyly in some species of the genus Linum L. (Linaceae) in Iran

, 2016
Heterostyly is the occurrence of flowers with different sexual organ arrangements in different plants of the same species. This floral polymorphism occurs in four sections of genus Linum.
