However, the floripondio is also a hallucinogenic plant. Its flowers cause psychotic episodes; alienation, paralysis and can become deadly. This is because it has trophic alkaloids, substances that are also present in synthetic drugs. And that inhibit the nervous system.

Fern Plants

Ferns are seedless vascular plants, whose most outstanding anatomical features are large leaves, commonly pinnate and with circinate prefoliation. Proverbially has associated 3 groups, being these the ferns leptosporangiados, marathiales and the opioglosales.

However, modern genetic analysis found that the opioglossals belong to the psilotales, which were proven to be classified separately as primitive, grouping together now in a single taxon named Ophioglossidae or Psilotopsida .

On the other hand, the monophyletic nature of the ferns has been questioned by several authors due to the results of the first molecular phylogenetic studies; however, it has been proven that they form a clear brother of the equisetos based on plastidial, nuclear and mitochondrial genetics.

Proverbially they have been grouped into two groups on the platform of the organization and advancement of the sporangia, that is, the marathiales and ofioglosales are exclaimed as a whole of eusporangiate ferns and the polyphodids are called as leptosporangiate ferns; although, the phylogenetic examinations declared that the eusporangiados are in fact a parafilético set in correspondence to the leptosporangiados.

Likewise, phylogenetically it can be fragmented into two groups – Ophioglossidae and the group popularly known as the true ferns   that today after the agreed molecular DNA analyzes were established that form a clear.
