The plant is often gathered from the wild for local medicinal use and is sold in local markets. Now containing plants.

The gogotense has a history as a traditional equiestum remedy, and a study of its diuretic effects on humans showed significant increases in urinary sodiumpotassiumand chloride. Human and animal trials of indicate that E. Year ISBN Description Includes articles on the commercial uses inclusing medicinal of ferns in Central America and the cultivation of the genus Dryopteris.

The tapetum disintegrates towards the end of the sporogenesis, leaving spores free within the sporangial cavity. Also in the Galapagos Islands. According to a recent study, [3] this species may be the most isolated of all the genus, being more closely related with bogotemse Equisetums rather than living ones.

Flowering plants Photograph by: Studies on some reproductive traits in Equisetum species are scarce and valuable to understand species distribution.

Immature sporocytes spore mother cells are tightly packed within the young sporangia. Sporoderm includes three layers external to the cytoplasmic membrane of the spore cell, and they are pseudoendospore, exospore and perispore.

Equisetum bogotense – Useful Tropical Plants

Tropical Plants Database, Ken Fern. It cam be downloaded from the Internet. Viewed with SEM, the exospore is smooth to rugulate, with micro perforations, while equiisetum perispore is muriform, rugate, with narrow, delicate, discontinuous, randomly distributed folds delimiting incomplete, irregular areolae, externally covered by of different size, densely distributed orbicules.

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 manubrium.

Spores present several cytological changes that allow them to achieve greater size and increase the number of plastids, before reaching the adult stage. This volume contains a monograph of the genus Zapoteca Calliandra amongst other things. The sporocytes quickly undergo meiosis, by passing the stage of archesporium and give origin to tetrads of spores. The plant occasionally invades abandoned cultivated fields equieetum its native range[ Title American Fern Journal Vol.

Views Read Edit View history. The tapetum loses histological 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.
