Abstract: Pollen morphology of five species from Magnolia is similar under LM.The sculptures are all foveolate except Magnolia grandiflora slightly coarse.The exine of the five species can be distinguished into tectum,columella and footlayer.The puncta in the tectum are clearly seen.The colpus memberane consists of a thin footlayer and intine while the sexine elements (tectum and columella) are reduced gradually.Spherical granules are frequently observed and mixed up with the small intraexinous spaces of several incipient columellae sometime in columella.Endexine very thin,distinct and continuous in Mgrandiflora and beneath the apertural area in Mdenudata.The development of columella speaks in favour of regarding the pollen of Magnolia as primitive.
