Objective]This study aims to get insight of the systematic position of Glyptostrobus pensilis and to explore developmental abnormalities of seeds of this species based on its reproductive developmental anatomy. Further to enrich and complement the current understanding of G. pensilis in reproductive biology and to provide a theoretical basis for designing conservation strategies for this species.[Method]During the period of three years from September,2011 to September,2013,we observed morphological changes from cone buds emergence to seed cones...
