Bot. 1: 538. 1880) as a synonym of Echinocactus spiralis, and Mclo- cactus besleri affinis (Forster, Handb. Cact. 320. 1846) doubtless are to be referred here. Echinocactus multangularis Voigt we do not know. It is cited by Schumann (Gesamtb. Kakteen 348) as a synonym of Echinocactus recurvus, but no place of publication is given. In the only list of Voigt which we have consulted (Hort. Suburb. Calcutt. 1845) he lists three species of this genus, viz. ottonis, eyriesii, and comigerus. These are followed by Cereus multangularis which suggests that a mistake has been made. Dr. John Hendley Barnhart suggests a different origin for the name of Echinocactus multangularis. It is to be noted that Forster's Handbuch appeared the next year after the appearance of Voigt's Calcutta List. Dr. Barnhart's note is as follows: "I do not think that you have the correct explanation of the name Echinocactus multangularis Voigt. Schumann's citation of this name as a synonym of E. recurvus appears to me to have been copied from the first edition of Forster's Handbuch (1846), page 316, where under E. recurvus you will find the synonym 'C (/. e., 'Cactus') 'multangularis Voigt.' In other words Schumann has simply made the slip of writing 'Echinocactus' instead of 'Cactus' for the Voigt name. The name 'Cactus multangularis Voigt' seems to go back in li
