This member of the Amaryllidaceae family was given this name by William Herbert in 1826. It is found in Argentine, Chile, Paraguay and Uruguay, growing in a well drained soil with some water and some to lots of sun. The bulb can grow to two and a half centimetres in diameter, the entire plant to 25 or even 30 centimetres in height. The flowers are white with a green centre.
The genera name is derived from the Green Ζέφυρος Zephyrus, the Greek god of the west wind, and ἄνθος anthos, meaning 'flower', referring to the slender stalks, a classical name compounded to indicate the western origin. The species name means 'white, glittering' for the flowers.
