Abstract:The morphogenesis of Canada goldenrod growing in north of Anhui province, China, was analyzed by light microscope（LM）,scanning electron microscope (SEM) and field observations in order to comprehensively understand the invasive structural foundation of the species. The results showed that the leaf has less stomata both on its upper and lower epidermis, cover with thick cuticle and long epidermal hairs to guard against water-losing; the structure of the leaf with well-developed vascular bundles and bundle sheath extension improves the conducting capability of photosynthetic products to meet the developmental needs of underground vegetative organs. The stem has structural characters of high ability to transport and support. The main root is prematurely developed to suit for the development of adventitious structures underground. Mature pollen grain belonging to evolutional type are enveloped by callose, which is propitious to pollination, but it′s florescence，inflorescence composing and not to establish relationship to native pollinator result in some capitulums infertile. The rhizome containing a high content of inulin has the material and structural basis to be the independent diasporas.
