5: 252. 1845 (Plantae Lindheimerianae 44, re-paged). In that 

 publication, under the description of Gonolobus cynaitchoides^ 

 Bngelman says : " From the description, there can be little doubt 

 that this plant is a congener of Chthamalia biflora, and C. pubi- 

 flora, Decaisne^ in DC. prodr.^ from which it differs in the glab- 

 rous corolla, etc.; but surely it cannot be separated from Gon- 

 olobus, as that genus is left by Decaisne." The writer can 

 find nothing in the above sentence to indicate that Engelman 

 published Gonolobus pubifiorus in it. Torrey is also credited 

 with the use of the same combination in Bot. Mex. Bound. 165. 

 What he actually says under Go?iolobus bijiorus^ is that " C. 

 (hthamalia) pubiflora, Decaisne^ I. c. is Gonolobus ■ prostratus of 

 Elliott, but not of R. Brown." Apparently the species was first 

 properly named under Gonolobus in 1876, as given in the above 

 citation.

In this connection it may be well to again refer to the fact 

 pointed out by the writer several years ago (Cont. Herb. F. & M. 

 Coll. 1: 79. 1895), that Rafinesque, and not Nuttall, is the author 

 of the name Gonolobus biflorus. He published it in New Flora, 

 4; 58. 1836. The name with Nuttall as its author was pub- 

 lished by Decaisne in DC. Prod. 8: 605. 1844, as a synonym of 

 Chthmnalia biflora. It is evident from comparison of the two 

 descriptions, and from the type stations, that only one species 

 was under consideration by the two authors, and that in all prob- 

 ability Rafinesque's description was taken from one of Nuttall's 

 specimens.
