Dignitas Personae is the title of a 2008 instruction by the Congregation for the Doctrine of the Faith giving doctrinal directives on certain embryonic ethical controversies that had emerged since 1987, after Donum Vitae was released.
The document takes a critical stance against selective reduction, prenatal diagnosis, preimplantation diagnosis, in vitro fertilization, cryopreservation, embryo transfer, some forms of genetic engineering, embryo donation, which have been criticized as unethical by anti-abortion ethicists because they provoke the termination of embryonic cell reproduction.
The doctrinal material is not only addressed to Catholic couples, but also to pharmacists, doctors, ethicists, theologians, politicians and industrialists so that they may try to tackle these issues together. Other related documents, such as Humanae Vitae, were also written for a wide variety of individuals and specialists on the matter.
Dignitas Personae also reiterates Church opposition to contraception and abortion, mentioning new methods of birth control such as female condoms and the morning-after pill.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
