“…Thus, while there are no similar studies in species related to D. polyclada, there may be peculiarities in the events of pollination in this species, due to occlusion of the corolla, as well as the distinct configuration of the androecium, features that may allow more inferences, not only of a reproductive nature, but also taxonomic, if assessed in other species. As for the relative position of the stamens and stigma in relation to the corolla, the morphometric data of the present study suggest that the exserted stigma in D. polyclada is due to the long style, however the exsertion of the stamens is not directly related to the relative size of the filament, since D. ibicuiensis presented the greatest values for this measure, but has included stamens, as was also observed by Carvalho et al (2016). We underline, however, that the exsertion in D. polyclada occurs after anthesis, due to the apparent increase in the lengths of the androecium and gynoecium, a common phenomenon in angiosperms, which can occur by cellular elongation, or even by the presence of intercalary meristems at the base of these organs (Greyson 1994).…”
