Description

Weberbauerocereus rauhii grows shrubby to tree-shaped with candelabra-like, upright shoots that have a diameter of 8 to 15 centimeters and reaches heights of up to 6 meters. A short trunk is formed. There are about 23 ribs. The areoles on it are gray. The up to six, very strong, yellow central spines have a darker tip and are 6 to 7 centimeters long. The numerous whitish-gray marginal spines are up to 1 centimeter long. Long bristles are present in the flowering area.

The somewhat zygomorphic, slightly fragrant flowers open at night and are up to 10 centimeters long. Its violet-brown flower tube is densely scaled. The outer bracts are reddish brown, the inner ones are white to pink or pinkish-brown. The fruits are brownish red to orange and reach a diameter of up to 3 centimeters. They are trimmed with white wool.[3]

Distribution

Weberbauerocereus rauhii is widespread in the Peruvian regions of Huancavelica, Ayacucho, Arequipa and Ica at altitudes of 500 to 2500 meters.

The first description by Curt Backeberg was published in 1957. The specific epithet rauhii honors the German botanist Werner Rauh. Nomenclature synonyms are Haageocereus rauhii (Backeb.) P.V.Heath (1995) and Echinopsis rauhii (Backeb.) Mayta (2015).
