Practice question

Epipetalous condition refers to stamens whose filaments are adnate to corolla tube, anthers remain free and introrse, ensuring pollen presentation near pollinator entry. This synorganization promotes effective nototribic and sternotribic pollination. Solanaceae displays five epipetalous, polyandrous stamens alternating with corolla lobes, valvate aestivation, superior ovary with swollen placenta. Fabaceae shows diadelphous condition not epipetalous, Malvaceae monadelphous staminal column, Brassicaceae tetradynamous free from petals. Presence of epipetalous stamens diagnostically identifies gamopetalous families evolved for specialized entomophily and buzz pollination in Solanum.
