yapon

Noun

yaupon (countable and uncountable, plural yaupons)

1. The yaupon holly, Ilex vomitoria, an evergreen holly shrub with white flowers and red or yellow berries, found in the south-eastern United States.
   • Yaupon is evergreen like the American holly and the familiar hollies of Christmas decorations, but the leaves of yaupon are small and smooth-edged rather than prickly. Easy to chew and blandly tasty, they would not stand out in a tossed salad.2002, Connie C. Barlow, The Ghosts of Evolution: Nonsensical Fruit, Missing Partners, and Other Ecological Anachronisms
2. A tea-like drink, "black drink", brewed from the leaves of this holly (or, sometimes, Ilex cassine).
