It is perhaps unfortunate that the language of flowers has not the same meaning to the horticulturist as to the botanist. So far as botany is concerned, the light flowered Atamasco lily - Zephyranthes Candida - is the same as Z. atamasco, and is given as a synonym of the latter in modern botanical works. But as horticulturists must keep the bright pink form separate from the whitish one, we have to recognize Zephyranthes Candida as especially denoting the latter. We might in common parlance say "White Fairy Lily " when referring to the Z. Candida, but as Z. Treatae is white also that would make confusion still.
