A NEW NYCTELEA NAME 



The most common species of this genus has been known lately, under 

 the American Code of Botanical Nomenclature, as Nyctelea nyctelea (L.) 

 Britton. Since, however, it is desirable to avoid the use of such duplicate 

 binomials, a new name must be found for this species. Adopting the next 

 available specific name, the plant may be known as Nyctelea ambigua 

 (Nutt.) Standi. (Ipomoea nyctelea L. Sp. PI. 160. 1753; Ellisia ambigua 

 Nutt. Gen. PI. 1: 118. 1818; Nyctelea nyctelea Britton, in Britt. & Brown, 

 Illustr. Fl. ed. 2. 3: 67. 1913. —Paul C. Standley.
