First report of Nerine latent virus in Haemanthus albiflos in the UK.

Abstract

Haemanthus albiflos is a flowering plant native to South Africa and Namibia. A member of the family Amaryllidaceae, it is an evergreen bulbous perennial with unusual flowers that give it the common name of paintbrush. Tolerance for indirect sunlight and neglect has made this a popular houseplant in countries where it would not survive the winter climate. One such house plant bought at a UK nursery in the late 1990's, was later recognized as showing mild streaking symptoms consistent with a virus infection. The causal pathogen was isolated and identified as Nerine latent virus (NeLV) based on molecular and pathogenicity analyses. This is thought to be the first report of NeLV on H. albiflos.
