Parajulidae is a family of millipedes in the order Julida, occurring predominantly in North America but also in Central America and East Asia. Parajulids are found from Alaska to as far south as Guatemala.[1] Male Parajulids have a greatly enlarged first pair of legs, and externally exposed gonopods, in contrast to the largely Eurasian family Julidae which have a small, hook-shaped first pair of legs, and gonopods concealed internally.[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.
