Abstract: Pollen morphology of 5 species in genus Tillandsia were observed by standard electronic modules (SEM). The results revealed the common features in their shape: i.e.1colporate and reticulate exine. All these showed that genus Tillandsia plants were more advanced in evolution than the other species within the same taxa. According to the unique pollen shape, we proposed that Tillandsia might be a relatively originate species in genus Tillandsia. The pollen size, mesh shape and space between meshes were different. Pollen morphology was one of major references in plant taxonomy.
