However, the gynoecium morpho-anatomy in South American species of Cactaceae that evolved in the Andean region remains largely unknown. Here we selected 18 species, most of them of evolutionarily related genera of Cactaceae tribe Trichocereeae, to conduct a detailed comparative study. Observations were made using light, fluorescence, differential interference contrast and scanning electron microscopy. Most of the characters of the ovary and ovule were typical of the family, except for the nucellar beak in Echinopsis aurea and E. haematantha, here reported for the first time in cacti. We found evidence suggesting that the stigmatic surface covered with multiseriate trichomes, the semi-closed style type and the pollen tube transmitting tract are conserved characters among species of Trichocereeae; this finding may be explained by a phylogenetic ...

In this work we evaluate the sexual expression, phenology, floral biology, and mating system in eight to sixteen individuals of the duodichogamous Koelreuteria elegans (Seem.) A.C. Sm. subsp. formosana (Hayata) F.G. Mey. Results from our study show that all individuals exhibited a pattern of flowering characterised by two cycles of pistillate flowers with an intervening one of staminate flowers. The synflorescences presented a high synchronisation between the male and female phases at the individual level. Therefore, very little functional overlap was observed between pollen receipt and pollen dispatch within individuals. Pollination was by bees, and the manual pollination experiments showed that this species is a xenogamous although self-compatible species. Nevertheless, seed set increased significantly with hand cross-pollination and open pollination experimen...
