This paper details an investigation on the anatomical structure of Cancriniadiscoidea (ldb. ) Pob. Epidermal cell of stem and leaf contains larger in numberchloroplasts. There are five long cracks on the cross section of stem. The blade is structure ofisobilateral leaf,but the petiole is the special structure of bifacial leaf.
