Equisetum reproduction Equisetum reproduces vegetatively and by means of spores. VEGETATIVE REPRODUCTION: The subterranean rhizomes of some species (e.g., E. telmateia, E. arvense) form tubers which, on separation from the parent plant, germinate to produce new sporophytic plants. The tubers develop due to irregular growth of some buds at the nodes of the rhizomes. REPRODUCTION BY SPORES Homosporous. Spores are produced within the sporangia. The sporangia are borne on the sporangiophores which are aggregated into a compact structure termed strobilus or cone or sporangiferous spike.
