< 'crciis suhtoi'tiiosits Hortus (Forster, Handb. Cact. 409. 1846) was given as a synonym 

 of Ccrcns lolitbriiuis. ( 'crcii* coliibriiius flai'is^uins Salm-Dyck (Cact. Hort. Dyck. 1844. 32. 

 1845) seems never to have been described though Schumann takes it up under C. baumannii 

 and attributes it to Salm-Dyck. Forster in his 

 Handbuch refers it as a synonym of C. colitbriints. 



According to Weingart, C. grossci (Monatsschr. 

 Kakteenk. 18: 8. 1908) is only a variety of this 

 species, while ('. anguiniformis (Monatsschr. Kak- 

 teenk. 18:6. 1908) is true C. \\inmamiii.

\\'t have known little of this species until quite recently. In 1917 Dr. Shafer collected 

 on a dry sandy bank at Caliligua, Jujuy, a plant (No. 69) which was sent to the New York 

 Botanical Garden, where it flowered while this volume was going through the press.
