Study on the Peculiar and Precious Species Resources of Mangolia in Henan

It is reported in this paper that there were 9 species, 1 subspecies, and 16 neo-superi- or varieties of peculiar, precious and rare species resources of Magnolia in Henan province, includ- ing 3 flower types of M. Honanensis, 4 leaf types of M. jigongshansis, the terminal and axillary flower of cyme type of M. axilliflora and M. axilliflora cv. 'Sijihua' and so on. Those could provide valuable information for studies on the theory of tevolution of reminal flower→both termi- nal and axillary fllower→cyme and the specise formation, inflorescence evolution and its relation- ship and population classification. 16 neo-superior varieties weve also introduced, which provides scientific proof for its development and popularization.
