Opuntia cardiosperma is a species of plant in the genus Opuntia ( Opuntia ) from the cactus family(Cactaceae). The specific epithet cardiosperma means '(Latin cardiospermus) with heart-shaped seeds'.
description
Opuntia cardiosperma grows as a shrub with more or less upright shoots, is richly branched and reaches heights of 1 to 2 meters. The cloudy, dark green, slightly sloping, narrow, elongated to obovate to elliptical, somewhat tuberous shoot sections are rounded at their tips and narrowed at the base. There is often a darker area around the areoles . The shoot sections are 9 to 20 centimeters (rarely up to 30 centimeters) long, 5 to 7 centimeters wide and 1 to 1.5 centimeters (rarely up to 2 centimeters) thick. The small, awl- shaped leaf rudiments on it are 3 to 5 millimeters long and soon fall off. The large areoles are 3 to 5 centimeters apart. They are covered with initially white and later graying wool. The brownish glochids are mostly hidden by the wool of the areoles. The one or two acicular-awl, stiff, protruding or ascending thorns are usually only formed on a few areoles. They are initially brownish and gray or become whitish with age. The thorns are 0.5 to 1 centimeter (rarely up to 2 centimeters) long.
The orange-colored flowers are about 7 centimeters long and 6 to 8 centimeters in diameter. The elongated to pear-shaped fruits are 3 to 7.5 inches long and 2 to 3.8 inches in diameter.
