Echinopsis bonnieae is a species of the genus Echinopsis in the cactus family(Cactaceae). The specific epithet bonnieae honors the American cactus lover Bonnie Brunkow, who discovered the species.
description
Echinopsis bonnieae usually grows individually. The slender cylindrical, gray-green to olive-green shoots , which are completely hidden by the dense thorns, reach heights of 10 to 15 centimeters (rarely up to 30 centimeters) with diameters of 1.5 to 2.5 centimeters. With a neck-like tapering section, they merge into a very large, often irregularly branched taproot . There are about 30 ribs , which are more or less vertically arranged and broken up into cusps. The areoles on it are hairy white and are about 1 millimeter apart. From them arise about ten comb-shaped, brownish pink, somewhat translucent thorns that turn gray with age. The awl thorns are thickened at their base and have a length of 1 to 1.5 millimeters.
The bell-shaped flowers are up to 2.5 centimeters long and have the same diameter. The outer bracts are dark yellow, the inner yellow. The pericarpel and the flower tube are covered with dark wool hair. The egg-shaped, dark purple fruits are 1.1 to 1.5 centimeters long. They tear open lengthways and contain up to 400 seeds .
Distribution and systematics
Echinopsis bonnieae is distributed in the Argentine province of Catamarca west of Fiambalá on dry, almost bare gravel slopes at altitudes of about 2000 meters.
