THE CACTACEA^. 



Cactus reptans Willdenow (Ann. Hort. Berol. Suppl. 33. 1813) was taken up in this 

 work by mistake as Cereus reptans. 



Cactus neglectus Dehnhardt (Rivist. Napol. i. 3: 166.), according to the Index 

 Kewensis, is a species of Pereskia. 



Cereus erinaceus is credited to Haworth by Steudel (Norn. ed. 2.1: 334. 1840) and said 

 to come from the West Indies. Steudel must have had in mind Cactus erinaceus Haworth ; 

 if so, the plant is from South America. 



Cereus torrellianus (Monatsschr. Kakteenk. 20: 42. 1910) is probably a misspelling for 

 C. tonelianus. 



Figure 263, shown below, gives a typical Arizona landscape in which Carnegiea gigantea 

 is the dominant plant.
