Lobivia tiegeliana

It is a small solitary cactus of a globular shape, slightly depressed at the apex. It has a dark green body, tending to purplish, when exposed to the sun, with tubercles, arranged in a slight spiral, with white areoles and extremely particular combed spines, that resemble a spider; each spine is quite robust and dark, tending to fade towards black at the end. During the flowering period its decorative aspect is extremely accentuated by large and abundant flowers of a beautiful deep red or, sometimes, bright yellow color.
