Leaf architectural and morphological characters of 28 taxa from Michelia, Paramichelia and Tsoongiodendron (Magnoliaceae sensu stricto, subtribe Micheliinae) were examined to gain a better understanding of the intergeneric relationships and the systematic positions of some species within Michelia.

This paper reports the pollen morphdogy of Paramichelia baillonii,as the only representativeof the genus from China and Tsoongiodendron odorum, the species of the monotypic genus,Thepollen grains of the 2 species show similariries under the LM and SEM,But the study under TEMshows differences of the 2 species:(1)The exine of T.
