Balsaminaceae in Southeast Asia: systematics, evolution, and pollination biology Naturalis
Ruchisansakun, S..
Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity. Its classification has changed many times throughout the taxonomic history of the group, owing to the emphasis on particular diagnostic characters. This suggests that patterns of character evolution are labile and do not contain much phylogenetic signal. This appears particularly prevalent among floral characters, suggesting that floral evolution and pollination ecology may be important drivers of diversification in the family. Further complications in taxonomy arise from the fact that one of the two genera of the family, Impatiens, has a very large number of species, and that it is distributed across several continents. This has led to a lack of taxonomic...

Reproductive biology in species of Bidens L. (Asteraceae) Scientia Agricola
Grombone-Guaratini,Maria Tereza; Solferini,Vera Nisaka; Semir,João.
Studies about reproductive biology of weed species can have implications on the establishment of controlling practices that minimize the effects of these weed populations on agricultural fields. The pollination biology of Bidens alba (L.) DC., B. pilosa L., and Bidens subalternans DC., was studied at different sites and climatic seasons. Bidens pilosa and B. subalternans are widely distributed in agricultural areas, in disturbed habitats, and along road sides. Bidens alba occur only along the coast. The three species are self-compatible and non agamospermous. The composition of the pollinator community changes during the year and between sites. Hymenopterans and lepidopterans are the most frequent visitors to Bidens species in both areas studied. Although...
