Abstract:

Based on field investigation and analysis, the cultivars in Osmanthus were classified according to their blossoming habit, inflorescence types, flower colors, flower types, ovary developing status, and characteristics of branches and leaves. 177 cultivars were recognized, including 157 cultivars in O. fragrans (18 in Siji Group, 57 in Albus Group, 45 in Luteus Group and 37 in Aurantiacus Group), 12 in O. heterophyllus, 3 in O. ×fortunei, 2 in O. cooperi and 3 in O. delavayi. The principles and ranks for cultivar classification were discussed, and a classification system was proposed. The scientific names of 4 groups in O. fragrans were revised.
