BB. KUNTZE AND HIS EETIEWZLS. 275

tlie genus, has questioned its Talidity, or been able to admit 

 tliat Mr. Bentliam did well in remandiug the species to Cleome. 

 So while Mr. Jackson with such complacency pronounces the 

 earliest of all Jacksonias a figment, we with a degree of equa- 

 nimity express our own and some other people's opinion by 

 writing it as an excellent genus. 



The one review among all those read by me which is 

 moderate in its censures, and duly appreciative of Dr. Kuntze's 

 immense and richly valuable labors, is that of Dr. Britton of 

 Columbia College; and this has been made elaborate to the 

 extent of a long list of the American genera affected by the 

 researches of the author of the " Eevisio." This list will 

 become one of the necessary adjuncts of critical work in 

 nomenclature in our country. The reviewer has given many 

 comments of his own at different places throughout the list, 

 upon only a few of which would I make any remark. 



The date of the first edition of Linnaeus' "Genera Plantarum" 

 (1737) is Dr. Britton's chosen starting-point ; but whether he 

 has ever considered the very extremely retroactive expressions 

 of the Paris Code, and whether he holds the Code to be his 

 law, I know not. He is struck with Dr. Kuntze's new 

 method of using the parenthetic author-citation, namely, that 

 of placing it after the name of the author of the combination 

 rather than before it, and finds this practice inexplicable. It 

 seems clear enough to me that by Dr. Kuntze's method a 

 point in obedience to the International Law is gained; for 

 that law demands, if I mistake not," that the name of the 

 author of a combination shall follow the combination immedi- 

 ately. Unless one count a parenthesis as nothing at all—to 

 which view, in my mind, little or no exception can be taken 

 the placing of it between the combination and the name of 

 the author of the combination violates the Code. 



In remarking upon the generic name Bursa as antedating 

 CapseUa, Dr. Britton says that the binary name for the com- 

 mon Shepherd's Purse becomes Bursa 2)nstoris; to which I
