| Abstract: | The microstructure features of seed from 6 species of rare and endangered in desert region of China were observed by using both optical microscope and scanning electron microscope. The results show that they have the fine and complex ornamentation on spermoderm and appeared abundant diversity. The features may be in relation to their own special location and habitats. |
