Cephalocereus hoppenstedtii. (See page 27, a«/g.) 



A wonderful display of this plant is shown in the photograph taken by C. A Purpus 

 near the type locality in 1912. A mountainside is shown with many of the plants which 

 form the consniniont; nhippfc in fhe. lotn/^c^^oT^^

Lemaireocereus griseus. (See page 87, ante.) 



Both Cereus eburnetis Salm-Dyck and Cactus ehurnens Link (Hnum. Hort. Berol. 2 : 22) 

 were published in 1822 and to both Cactus peruvianus Willdenow (Enum. Hort. BeroL 

 Suppl. 32. 1813) was referred. Willdenow's plant, from the description, suggests a Ceph- 

 alocereus but is referred to Cereus eburneus by the Index Kewensis. Link also refers it 

 to Hortus Dyckensis and to Haworth (Syn. PI. Succ. 179), while Salm-Dyck's descrip- 

 tion indicates that he had a plant before him different from Willdenow^s. The Cereus 

 eburneus described by Pfeiffer (Enum. Cact. 90) was certainly a complex, a part coming 

 from Curagao and a part from Chile. For this reason, doubtless, Schumann (Gesaratb. 

 Kakteen 59, 108) has referred both names to Cereus coquimbanus and Cereus eburneus.
