A non-commercial (also spelled noncommercial) activity is an activity that does not, in some sense, involve commerce, at least relative to similar activities that do have a commercial objective or emphasis.[citation needed] For example, advertising-free community radio stations are typically nonprofit organizations staffed by individuals volunteering their efforts to air a wide variety of radio programming, and do not run explicit radio advertisements, included in the United States specific grouping of "non-commercial educational" (NCE) public radio stations. Some Creative Commons licenses include a "non-commercial" option, which has been controversial in definition.[1]

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.
