Cereus brachiatus Galeotti (Salm- 

 Dyck, Cact. Hort. Dyck. 1849. 195. 1850) 

 must be very close to L. hollianus, if not 

 identical, although Schumann did not 

 believe they were the same; both came 

 from near Tehuacan, Mexico. Cereus mi- 

 litaris calijornicus (Schumann, Gesamtb. 

 Kakteen 85. 1897) is said to be a horti- 

 cultural form of Cereus bavosus.
