Outline of Final Research Achievements |
This study clarified the following points about evolution in flower and えmbembryological characters of Aquifoliales (Aquifoliaceae, Cardiopteridaceae, Helwingiaceae, Phyllonomaceae, and Stemonuraceae). (1) Synapomorphies for Helwingiaceae and Phyllonomaceae include epiphyllous inflorescences, inferior ovaries, disk nectary, and tenunucellate ovules. (2) Autapomorphies for Phyllonomaceae include monochasial cymes, glandular trichomes on sepal margin, a gynoecium composed of two carpels usually in transversal position, parietal placenta, ovule number increase, and exotestal seeds. (3) Autapomorphies for Helwingiaceae include loss of petals, obhaplostemy, and ambophily. (4) Cardiopteridaceae and Stemonuraceae likely share a gynoecium composed of two carpels usually in adaxial and abaxial positions.
