Apium virus Y Apium virus Y "Apium virus Y" (ApVY) is a plant pathogenic virus in the genus "Potyvirus" and the virus family "Potyviridae". Apium virus Y is a recently described member of the potyvirus family. It was first found in Australia in 2002 in poison hemlock ("Conium maculatum": an immigrant weed in Australia). A survey of native and weed species in the family Apiaceae found ApVY to be widespread in Australia. In addition, this survey and others found two other potyviruses. One was a well-known potyvirus infecting the Apiaceae, "Celery mosaic virus" (CeMV). CeMV has been found in celery ("Apium graveolens") crops
Cooperia (plant) Cooperia (plant) Cooperia was a genus of tender herbaceous perennials native to South America and the southern reaches of North America. They were closely related to "Zephyranthes" and "Habranthus", all of which are members of the amaryllis family, Amaryllidaceae. All three genera were commonly known as rain lilies because of their propensity for blooming after rains. "Cooperia" blooms in summer and fall. Although "Cooperia" was considered distinguishable from the better known rain lily genus, "Zephyranthes", by its fragrance similar to primroses, its white or yellow pollen, its tolerance for drout and desert conditions (Howard 2001:54) and tendency to be night-blooming
