Narcissus is a genus of perennial herbaceous bulbiferous geophytes, which die back after flowering to an underground storage bulb.They regrow in the following year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5–80 centimetres (2.0–31.5 in) depending on the species.
''Narcissus white streak virus (NWSV) is a plant pathogen of the family Potyviridae which infects plants of the genus Narcissus, and is transmitted by aphids. [1] It is among the commonest and most serious of the viral infections that infect narcissi, [ 2 ] [ 3 ] but appears to be confined to N. tazetta .

Narcissus degeneration virus (NDV) is a plant pathogenic Potyvirus of the family Potyviridae which infects plants of the genus Narcissus. It is one of the most serious and prevalent of the approximately 21 viruses which infect this genus. [1] [2] NDV is associated with chlorotic leaf striping in N. tazetta. [3]
Narcissus symptomless virus was described as a separate virus taxon in 2006. [4] Subsequently, in 2016 it became apparent that the nucleotide sequence identities between Narcissus symptomless virus and the partial genome sequences of Nerine latent virus are 94-97% for coat protein and replicase, well above the threshold 72% set for speciation of flexiviruses.
Narcissus common latent virus (NCLV) is a plant pathogenic virus. It infects Narcissus plants. The term 'latent' refers to the fact that infection may be symptomless.
Narcissus yellow stripe potyvirus (NYSV) is a plant pathogenic Potyvirus of the family Potyviridae which infects plants of the genus Narcissus. [2] It is one of the commoner viruses infecting Narcissus, and is transmitted by aphids .
Narcissus mosaic virus (NMV) is a plant pathogenic virus in the genus Potexvirus and family Alphaflexiviridae, which infects Narcissus. It can also affect Iris ...
