Echinopsis pentlandii, synonyms including Lobivia pentlandii, is a species of Echinopsis found in Bolivia and Peru. [3] [4]
Echinopsis pentlandii usually grows in groups with spherical to ovoid, bright green and often glaucous shoots that reach a diameter of up to around 12 centimeters. The shoot apex is often sunken. There are twelve to 15 high ribs that are deeply notched and divided into long, hatchet-shaped, sharp-edged cusps. The areoles on it are about 2 centimeters apart. Variable thorns emerge from them. The single central spine, which can also be missing, is 3 to 9 centimeters long. The backward curved 5 to 15 marginal spines are yellowish brown and are up to 3 centimeters long.
The short, funnel-shaped flowers open during the day and are variable in flower color. It ranges from slightly purple-pink to red, orange or yellow. The flower throat is often lighter. The flowers are 4 to 6 centimeters long. Its very strong flower tube reaches a diameter of up to 1 centimeter. The spherical, juicy, sticky fruits have a diameter of 1 to 1.2 centimeters. [5]
The species was first described by William Jackson Hooker in 1844 as Echinocactus pentlandii. [3] [6] The specific epithet pentlandii honors the Irish geographer and naturalist Joseph Barclay Pentland.[ citation needed ] In 1846, the species was transferred to the genus Echinopsis. [3] In 1922, Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Lobivia. [3] [7] As of November 2025 [update] , Plants of the World Online restored the species to Echinopsis. The species has many other synonyms, including a large number of varieties not accepted by Plants of the World Online. [3]
Echinopsis pentlandii is widespread in the Peruvian regions of Cusco and Puno and the Bolivian departments of La Paz, Oruro, Cochabamba and Potosí in the high altitudes of the Andes.[ citation needed ]
