The article discusses the structural details of seed coat Ephedra and also mentions its taxonomic significance. Topics discussed include seed coat morphology and ultrastructure of angiosperms, importance of epidermal characters in delimitating Pteridospermales, Bennettitales and Cycadales, phylogenetic relations of seed coats.

The article focuses on the study of epidermal features of the stem and leaf of G. biloba L., a gymnosperm, and its biochemical and therapeutic features. It mentions that the study showed presence of wax rodlets on the seed coat of G. biloba L. It states that photographs were taken by using scanning electron microscope (SEM) and energy dispersive X-ray analysis was performed to record the chemical nature of the wax rodlets on the seed coat.

The article offers information on the occurrence of non-protoplasmic mineral deposition in photosynthetic organism. It states that biomineralization of calcium crystals is of common occurrence in all photosynthetic organisms from small algae to angiosperms and giant gymnosperms. It mentions that occurrence and abundance in specific tissues of various plants are so constant that they are often used as a taxonomic tool.
