Cercus fulvibarbis Otto and Dietrich (Allg. Gartenz. 6: 28. 1838; Cereus chilensis ful- 

 vibarbis Salm-Dyck in Walpers, Repert. Bot. 2: 276. 1843), said to have come from Chile, 

 is referred to Cereus chilensis by Schumann, but it is described as having 10 to 13 ribs. 



Cereus polymorphus G. Don (Loudon, Hort. Brit. 195. 1830) and Cactus polymorphus 

 Gillies (published here as a synonym), referred to Cereus chilensis by Schumann, can not be 

 identified from the meager description. It is said to have been introduced from Chile in 

 1827. 



The following names belong here; they have not been accompanied by descriptions. 



Cereus quintero Pfeiffer, Enum. Cact. 86. 1837. 



chilensis brevispinulus Salm-Dyck in Walpers, Repert. Bot. 2: 276. 1843. 

 spinosior Salm-Dyck in Forster, Handb. Cact. 377. 1846. 

 flavescens Salm-Dyck, Cact. Hort. Dyck. 1849. 44. 1850. 

 eburneus (Schumann, Gesamtb. Kakteen 63. 1897) based on Eitlyclmia ebnrnea Philippi, 



must belong here. 



linnaei Schumann, Gesamtb. Kakteen 63. 1897. 

 quisco Weber in Hirscht, Monatsschr. Kakteenk. 8: no. 1898. 



Cereus spinibarbis var. minor Monville and var. piirpureus Monville (Labouret, Monogr. 

 Cact. 334. 1853) have been referred here. 



Cereus elegans Lemaire and C. dulcdcvantii Lemaire (Illustr. Hort. 5: Misc. 10. 1858), 

 unpublished, doubtless were given to forms of this species. Echinocactus pyramidalis and 

 E. elegans (Pfeiffer, Enum. Cact. 86. 1837) were given only as synonyms of Cereus chilensis.
