The publication of two varieties of flowering-dogwood under 

 the generic name Cynoxylon by the present writer in Bull. 

 Torrey Club 60: 56-57 (1933) was done before his attention 

 was called to the fact that this name was not proposed as a 

 generic name by Rafinesque in Alsog. Amer. (1838), but only 

 as a subgeneric one [vid., O. A. Farwell, Rhodora 34: 29-30. 

 1932]. The name Cynoxylon Raf. does not start as a genus, then, 

 until 1893, when it was inadvertently raised to generic rank by 

 Jackson in the Index Kewensis. The generic name Benthamidia 

 Spach (Hist. Veg. Phan. 8: 106. 1839) therefore antedates 

 Cynoxylon by fifty-four years, and the name for the common 

 flowering-dogwood of this region should be Benthamidia fiorida 

 (L.) Spach. The two varieties must then be renamed as follows: 



Benthamidia fiorida var. pendula (Dipp.) comb. nov. 



Cornns florida var. pendula Dipp. Handb. Laubh. 3: 244. 

 1893. 

 Benthamidia fiorida var. rubra (Andre) comb. nov. 



Cornus florida var. rubra Andre, Rev. Hort. 66: 500. 1894. 



Continued monographic work in the Verbenaceae has re- 

 vealed the fact that several new names and combinations are 

 required for some common tropical and subtropical forms of 

 this most interesting and complex group. Among these are the 



following: 



Amasonia campestris (AubL) comb. nov. 



Taligalea campestris Aubl. Hist. PI. Guian. 2: 625, pi. 252. 

 1775. 

 Bouchea Rusbyi nom. nov. 



Bouchea incisa Rusby, Bull. N. Y. Bot. Gard. 4: 432. 1907 

 [not B. incisa Pearson, Trans. S. Afr. Phil. Soc. 15: 

 180. 1904]. 

 Callicarpa incana (Turcz.) comb. nov. 



Aegiphila incana Turcz., Bull. Soc. Nat. Mosc. 36 2 : 218. 

 1863. 

 Chascanum adenostachyum (Schau.) comb, nov. 5 



Bouchea adenostachya Schau. in DC. Prodr. 11: 560. 1847. 

 Chascanum caespitosum (Pearson) comb. nov. 



6 For details concerning the differences between the genera Bouchea and 

 Chascanum, see the monograph of the former genus by Myrle E. Grenzebach 

 in Ann. Mo. Bot. Gard. 13: 80-100. 1926.
