Abstract:

Lilieae include 5 genus, Cardiocrinum, Lilium, Notholirion, Nomocharis and Fritillaris in A.Takhtajan system. We observed seeds of 23 species in these five genus in three aspects, seed structure, seed coat structure and exotesta characte under SEM. There are rela-tive differences in embryo size and shape, cuticle layer on testa and the characte of exotesta under SEM. These differnces are important seed morphological features to divide these 5 ge-nus. According the seed morpgological features, specially the exotesta charates under SEM, we think 1.Cardiocrium, Lilium etc are independent genus respectively. 2.their seeds belong to same type, Lilieae is a unaffected tribe.3.for the similarity of exotesta cell, Lilium souliei may be Nomocharis souliei.
