| Abstract: | Experiment were conducted on the morphological and anatomic structure of stem and leaf tissue of _Huperai crispate _Ching. The spore and sporangium morphological structure was observed using by scanning electron microscope.The results showed that the stele of stem is a transitional form of actinostele and plectostele with exarch xylem.The leaf has isolated mesophyll with exarch phloem vein.Problems existing in themicro propagation of different organs and tissue was pointed out and analyzed. |
