Both of these specimens are in the Kew Herbarium and a

 University. 



Mellichampia ligulata (Bcnth.) 



Ensknia ligulata Benth. PI. Hartw. 290. 1848. 



Mtilichampia rubcsccns K. Gray ; S. Wats. Proc. Am. Acad. 22 : 

 437. 1887. 



For some time past I have suspected the identity of Mclli- 

 chainpia with Enslenia ligulata and through the courtesy of the 

 Director of the Royal Gardens at Kew, I have obtained a tracing 

 of the type of the latter plant which confirms the suspicion. Be- 

 sides the type from Aguas Calientes, South Mexico, it has been col- 

 lected in the State of Jalisco, at Guadalajara, by Dr. Palmer, no. 

 280, July-October, 1886, and by C. G. Pringle, in copses near 

 Guadalajara, no. 5432, Aug., 1893. ^^r. Hemsley (Biol. Centr. 

 Am. 2: 358) also quotes a specimen without locality from Herb. 

 Pavon as belonging to this species. The specimens distributed as 

 Enslenia ligulata by Pringle (no. 4494) and Anipdanus ligulata by 

 A. A. Heller (no. 1899) are species o^ Roulinia. 



II. THE TYPES OF GONOLOBUS MICHAUX AND DESCRIPTIONS OF NEW SPECIES IN 



VINCETOXICUM WALTER 



The types of the three species of Gonolobus (Michx. Fl. Bor. 

 Am. I : 119) are preserved in the Herbarium of the Museum in 

 the Jardin des Plantes, Paris, where they are represented by several 

 specimens each, all in a somev/hat fragmentary condition, though 

 quite recognizable and agreeing with the descriptions. In the 

 Richard Herbarium (Herbarium of M. Drake del Castillo, Paris) 

 the actual specimens owned and described by Richard in the Fl. 

 Bor. Am. can be seen and they are in every way exact duplicates
