Cumulopuntia pentlandii is a species of plant in the genus Cumulopuntia fromthe cactus family (Cactaceae). The specific epithet pentlandii honors the Irish geographer and naturalist Joseph Barclay Pentland (1797–1873).
description
Cumulopuntia pentlandii forms more or less dense cushions. The grass-green, spherical to briefly egg-shaped shoot sections are up to 2.5 centimeters long. In old age they become wider than they are long. The initially low humps on it are later missing. On the upper part of the shoot sections sit ten to 15 areoles , which are covered with yellowish wool. The top of them are thorny. At the lower edge of these areoles there are one to six whitish, bristle-like, spreading and bent thorns . Occasionally, some shoot sections are thornless.
The yellow or red flowers reach lengths of up to 3 centimeters. On the upper part of the wide pericarpel there are some thornless areoles. The barrel-shaped, almost thornless fruits are up to 3.5 centimeters long.
