The article presents information on a study conducted on silica deposition in the plant Equisetum arvense, also known as horsetail. Silica deposits were observed in all regions of the plant from the rhizome through to the stem, leaf and spores. Various structures in the plant were silicified including cell walls, cell plates, plasmodesmata, and stomata at varying stages of differentiation. The study suggested that callose might be templating silica deposition in horsetail.

Previous studies on the carinal canals in several Equisetum species suggest that they convey water from one node to another. Methods Cell wall composition and ultrastructure...
