Lobivia ferox, is a species of Lobivia found in Bolivia and Argentina.
Description
Lobivia ferox grows individually, spherical to briefly cylindrical and reaches a height of 20 to 30 (up to 50) cm and up to over 30 cm in diameter. The approximately 30 ribs run in a spiral shape and are covered with sharp-edged humps. The oval areoles are about 3 cm apart and have a light wool felt. The thorns can almost completely cover the body, are long, stiff, curved to straight, sometimes hooked, light brown to horn-colored, darker in new growth and later graying. There are 2 to 5, up to 18 cm long, upwardly curved central spines and 8 to 14 marginal spines that are 3 to 7 cm long and radiate out to the sides.
The funnel-shaped flowers reach a length of 9 to 11 (up to 13) centimeters and have a diameter of 6 to 8 (up to 10) centimeters. They appear laterally in the upper half of the shoot. The color of the petals varies between white, pink, purple, yellow and orange, the stamens are yellowish and protrude above the greenish hubs. The flower tube is greenish with pointed scales, the axils of which appear darker and are covered with gray wool. The spherical to barrel-shaped fruits are greenish and tearing. The black-brown seeds are 1.5 mm long and 0.7 mm thick.
Distribution
Lobivia ferox is widespread in Bolivia in the departments of Oruro, Potosí, Chuquisaca and Tarija, in Argentina in the provinces of Jujuy and Salta and in Chile in the province of Iquique. It grows at altitudes from 2000 to 3500 m (in Chile up to 4000 m). The large distribution area results in a corresponding variety of forms.

The first description was made in 1922 by Nathaniel Lord Britton and Joseph Nelson Rose. The specific epithet ferox comes from Latin, means 'wild' and refers to the thorns of the species. Nomenclature synonyms are Echinopsis ferox (Britton & Rose) Backeb. (1934), Pseudolobivia ferox (Britton & Rose) Backeb. (1942) and Furiolobivia ferox (Britton & Rose) Y.Itô (1957).
