Yerba

Yerba maté or yerba-mate, Ilex paraguariensis, is a species of holly (family Aquifoliaceae) native to subtropical South America in northeastern Argentina, Bolivia, Paraguay and southern Brazil. It was first scientifically classified by Swiss botanist Moses Bertoni, who settled in Paraguay in 1895.

The yerba mate plant is a shrub or small tree growing up to 15 meters tall. The leaves are evergreen, 7–11 cm long and 3–5.5 cm wide, with a serrated margin. The flowers are small, greenish-white, with four petals. The fruit is a red drupe 4–6 mm in diameter. (wikipedia)
