| Clades[1] | |
The superasterids are members of a large clade (monophyletic group) of flowering plants, containing more than 122,000 species.[citation needed]
The clade is divided into 20 orders as defined in APG IV system. These orders, in turn, together comprise about 146 families.[1]
The name is based upon the name "Asteridae", which had usually been understood to be a subclass.
Relationships[edit]
The asterids, Berberidopsidales, Santalales, and Caryophyllales form the superasterids clade.[2] This is one of three groups that compose the Pentapetalae (core eudicots minus Gunnerales),[3] the others being Dilleniales and the superrosids (Saxifragales and rosids).[2]

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.
