Spores present several cytological changes that allow them to achieve greater size and increase the number of plastids, before reaching the adult stage. The tapetum loses bogoyense integrity during early stages of sporogenesis, intrudes as a plasmodial mass into the cavity of the sporangium, partially surrounding premeiotic sporocytes, and then, tetrads and adult spores.

Strobili have numerous mature sporangiophores, each one with a peltate structure, the scutellum, bearing five-six sessile sporangia attached to the axis of strobilus by the equiisetum. This volume contains a monograph of the genus Zapoteca Calliandra amongst other things.

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

The sporocytes quickly undergo meiosis, by passing the stage of archesporium and give origin to tetrads of spores. Evolution of horsetails Equisetales within the major euphyllophyte clade Sphenopsida”.

Tropical Plants Database, Ken Fern. The tapetum disintegrates towards the end of the sporogenesis, leaving spores free within the sporangial cavity.
