The Andean horsetail Equisetum bogotense is a herbaceous perennial that reproduces through spores.

[Sporogenesis and spores of Equisetum bogotense (Equisetaceae) from mountain areas of Colombia].

Also in the Galapagos Islands. The sporocytes quickly undergo meiosis, by passing the stage of archesporium and give origin to tetrads of spores.

Viewed with SEM, the exospore is smooth to rugulate, with micro perforations, while the perispore is muriform, rugate, with narrow, delicate, discontinuous, randomly distributed folds delimiting incomplete, irregular areolae, externally covered by of different size, densely distributed orbicules.

These orbicules are also found all over the external face and margins of the elaters, equisetu the internal face is smooth and lack orbicules.
