| Abstract: | According to field investigation data and correlative references, organ morphology variation and flora composition of Compositae plant in natural grassland of Bashang District in Hubei Province were studied. Results showed that the wild Compositae plant in this region had about 34 genera and 67 speices. Among them, monotypic genera and oligotypic genus were in the majority, accounted for 97.1% of the total genera. Plant flora composition had 7 areal types and 5 formas with significant temperate nature. The organs of Compositae plant, such as root, stem, leaf, flower and fruit, had various morphological characteristics. |
