phinium as put together such plants as are here commented on. 

 There are other differences almost as important, and we have 

 not the slightest hesitancy of admitting these, as generically 

 characteristic, and proposing that such heterogenous mixtures 

 of widely different types be separated. 



A name of the group of perennials with three-follicled fruit 

 given by Spach, is Delphinastnim,^ not a desirable one as the 

 ending astntm indicates the wild condition of a plant, and is built 

 on a previously existing plant name. Staphisagria vSpach^ as also 

 his Phledininm^ are perhaps sufficiently different from either of 

 the above to merit recognition as genera. Delphidium^ Raf., another 

 name was proposed earlier than any by Rafinesque, but was 

 unfortunatelv made without description and even designation 

 of type and is scarcely more than a nomen nudum. vSome of the 

 transposed plants under Delphinastrum Spach are:
