Echinocactus terscheckii Reichenbach (Terscheck, Suppl. 3; also Walpers, Repert. Bot. 2: 
3i5- 1843). 
Echinocactus rosaceus (Otto, Allg. Gartenz. 1: 364. 1833), E. acutangulus Zuccarini 
(Pfeiffer, Enum. Cact. 55. 1837), and E. conquades (Forster, Handb. Cact. 338. 1846) 
have usually been referred to Echinocactus corynodes but were never described. 
Echinocactus erinaceus elatior Monville (Salm-Dyck, Cact. Hort. Dyck. 1844. 22. 
1845), without description, must be referred here.

This plant was first described in the Seed Catalogue of the Botanical Garden of 
Hamburg. The next year Lehmann published two descriptions of it under the name of 
Cactus ( Echinocactus ) langsdorfii, one of which was accompanied by a colored illustration 
(see second illustration cited above). We have seen no living plants or other illustrations 
which we are disposed to refer here and we have therefore kept the species distinct,
