Lemaireocereus beneckei (Ehrenberg) Britton & Rose
Publication The Cactaceae 4: 273 (-274), fig. 247 (1923).
Basionyme Cereus beneckei Ehrenberg
"14a. Lemaireocereus beneckei (Ehrenberg).
Cereus beneckei Ehrenberg, Bot. Zeit. 2: 835. 1844.
Cereus farinosus Haage in Salm-Dyck, Allg. Gartenz. 13: 355. 1845.
Cereus beneckei farinosus Salm-Dyck, Cact. Hort. Dyck. 1849.49. 1850.
Piptanthocereus beneckei Riccobono, Boll. R. Ort. Bot. Palermo 8: 226. 1909.
Plants 4 to 5 meters high, much branched; branches 6 to 7 cm. in diameter, the growing tips very glaucous; ribs 7 or 8, strongly tuberculate, obtuse, separated by narrow intervals; areoles small, circular, borne on the upper side of the tubercle, brown to black-felted; spines 1 to 7, acicular, the longest sometimes 2.5 cm. long, brown to black; flowers night-blooming, small, 4 cm. long, greenish brown without; inner perianth-segments rose-colored to white (?); ovary globose, glaucous, tuberculate, its areoles brown-felted and bearing 3 to 7 acicular spines, the longest sometimes 2.5 cm. long and brown to black; fruit about 2 cm. in diameter, somewhat tubercled, bearing clusters of spines at the areoles, red; pericarp thick, somewhat fleshy: pulp disappearing, leaving the large seeds loose, these escaping by a basal pore as in Oreocereus and many of the Echinocactanae.
Type locality: Mexico on red lava beds.
Distribution: Central Mexico.
In volume II of The Cactaceae (p. 18), we described this plant under Cereus but with the statement that it was not a true Cereus; we were not then able to refer to any known genus. At that time we knew little about the flowers and nothing accurate about the ovary and fruit. In 1921 Professor K. Reiche sent us some living plants from Iguala, the station from which Dr. Rose obtained his plants in 1905. These contained some old withered flowers and some well-developed ovaries which have enabled us to refer the plant to Lemaireocereus.
Figure 247 is from a photograph of K. Reiche's plant, slightly reduced, showing the top of a branch bearing an old flower and a half-ripe fruit."
Ainsi que l'expliquent Britton et Rose, le manque de renseignements sur les fleurs et l'absence d'ovaire ou de fruit ne leur avait pas permis de remettre formellement en cause le classement de cette espèce dans le genre Cereus dans le second volume de leur ouvrage The Cactaceae (2: 18-19 (1920)) consacré notamment aux cierges:

The following species have been described under Cereus, but their flowers are unknown or incompletely described:
CEREUS BENECKEI Ehrenberg, Bot. Zeit. 2: 835. 1844.
Cereus farinosus Haage in Salm-Dyck, Allg. Gartenz. 13: 355. 1845.
Cereus beneckei farinosus Salm-Dyck, Cact. Hort. Dyck. 1849.48. 1850.
Piptanthocereus beneckei Riccobono, Boll. R. Ort. Bot. Palermo 8: 226. 1909.
Plants 4 to 5 meters high, much branched; branches 6 to 7 cm. in diameter, the growing tips very glaucous; ribs 8, strongly tuberculate, obtuse, separated by narrow intervals; areoles small, borne on the upper side of the tubercle, black-felted; spines 1 to 5, acicular, about 1 cm. long, brownish; flowering areoles without wool; flowers small, less than 4 cm. long, greenish brown, night-blooming; inner perianth-segments rose-colored; fruit small, spineless.
Type locality: Mexico on red lava beds.
Distribution: Central Mexico.
This species is reported by Dr. Purpus from near Tehuacán, Mexico, while Dr. Rose collected it at Iguala Canyon, Guerrero, Mexico, in 1905. This latter specimen is now growing in the New York Botanical Garden, but has never flowered. It is not a true Cereus nor is it referable to any genus which we know. It is characterized by its peculiar tuberculate ribs and small flowers. It was named for A. Benecke, a dealer in succulents, at Birkenwerder near Berlin. Echinocactus farinosus (Förster, Handb. Cact. 396. 1846) is a synonym.
