. The Cactaceae : descriptions and illustrations of plants of the cactus family. . Fig. 93.—Denmoza rhodacantha. Type locality: Not cited at place of publication, but doubtless Mendoza, Argentina. Distribution: Western mountains of Argentina. Vaupel (Monatsschr. Kakteenk. 31: 13. 1921) gives an interesting description of the species which flowered in Berlin in 1920 where it is grown as Cereus erythrocephalus. Pfeiffer gives Echinocactus coccineus (Knum. Cact. 50. 1837) as a synonym, while Weber gives Cereus rhodacanthus Weber (Diet. Hort. Bois 472. 1896) as a synonym, but neither is described.

Don (Loudon, Hort. Brit. 194. 1830; Cactus coccineus Gillies), said to have come from Chile, is also to be referred here. Schumann refers here Echinopsis aurata Salm-Dyck and Echinocactus dumesnilianus Cels but these references are very doubtful; they probably belong to Eriosyce ceratistes. The following varieties have been referred to this species: Echinocactus rhodacanthus coccineus Monville (Labouret, Monogr. Cact. 304. 1853), Echinopsis rhodacantha aurea (Monatsschr. Kakteenk. 17: 76. 1907) and Echinopsis rhodacantha gracilior Labouret (Monogr. Cact. 304. 1853). Illustrations: Bliihende Kakteen 1: pi. 16; Monatsschr. Kakteenk. 4: 187. f. 3; Mollers Deutsche Gart. Zeit. 25: 481. f. 12, as Echinopsis rhodacantha. Plate viii, figure 2, shows a flower of a plant brought by Dr. Rose to the New York Botanical Garden in 1915, which bloomed in 1917.

Russell at Mendoza, Argentina, in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Britton, Nathaniel Lord, 1859-1934; Rose, J.
