"3. Erdisia meyenii nom. nov.
Cereus aureus Meyen, Allg. Gartenz. 1: 211. 1833. Not Salm-Dyck, 1828.
Cactus aureus Meyen, Reise 1: 447. 1834.
Echinocactus aureus Meyen in Pfeiffer, Enum. Cact. 68. 1837.
Cleistocactus aureus Weber in Gosselin, Bull. Mens. Soc. Nice 44: 39. 1904.
Stems subterranean, often forming large colonies sending up short, usually unjointed branches; joints 10 to 20 cm. long, 3 to 5 cm. in diameter, more or less clavate; ribs 5 to 8, high (1cm. high or more), somewhat undulate; spines several, subulate, unequal, brown to blackish, the longest 5 to 6 cm. long; flowers small, about 4 cm. long, yellow; scales on ovary and flower-tube small, 3 to 4 mm. long, acute, bearing felt and spines in their axils; fruit 2 cm. in diameter, reddish.
Type locality: Cordilleras de Tacna, Chile (formerly Peru), 600 meters altitude.
Distribution: Northern Chile and near Arequipa, Peru.
Dr. Rose found this plant (No. 18801) very common on the dry hills below Arequipa, Peru, growing mostly underground. The separated branches at first seemed to represent distinct plants; it is inconspicuous, its purple stems with black spines resembling a dead plant.
Meyen's Travels is usually cited as the original place of publication for this species, but it was published a year earlier as Cereus aureus. This last combination has usually been credited to Schumann (Gesamtb. Kakteen 124. 1897). The name assigned to this plant being a homonym, we have renamed it for its discoverer, Franz Julius Ferdinand Meyen (1804-1840), a celebrated traveler and writer.
Figure 156 shows a branch collected by Dr. Rose near Arequipa, Peru, in 1914."

Un nom nouveau pour Cereus aureus. En effet le nom de Cereus aureus publié par Meyen en 1833 était invalide car De Candolle avait déjà publié un Cereus aureus Salm-Dyck dans le Prodromus de 1828 (3:465). Mais la plupart des botanistes préfèrent considérer le reclassement opéré par Meyen en 1834 dans le genre Cactus comme un nom nouveau et le vrai basionyme.Publication:
