Articulavirales is an order of segmented negative-strand RNA viruses which infect invertebrates and vertebrates.[2] It includes the family of influenza viruses which infect humans. It is the only order of viruses in the monotypic class Insthoviricetes.[3] The order contains two families and eight genera.[1] Metatranscriptomics of aquatic animal samples paired with phylogenetics suggests that Articulavirales exhibits complex cross-species virus transmission and virus-host co-divergence over deep evolutionary time scales. Potentially originating in ancient aquatic animals at least 600 Mya.[4]
Etymology[edit]
The order name Articulavirales derives from Latin articulata meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders -virales.[3] The class name Insthoviricetes is a portmanteau of member viruses "influenza, isavirus, and thogotovirus" added to the suffix -viricetes for virus classes.[3]
Genome[edit]
Member viruses have segmented, negative-sense, single-stranded RNA genomes.[2]
Classification[edit]
The order Articulavirales contains two families and eight genera:[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.
