development, without regard to the number or selection of the 
generic characters, and under this view the name should be 
Puccinia poculiformis, as this is the oldest specific name applied 
to any phase of the species. But Magnus and Saccardo hold that 
this would imply that Jacquin had intended to include the teleuto- 
sporic stage under his nam epocuUforme, which of course is un¬ 
true; and Saccardo further holds that it would also imply that 
the teleutosporic stage, which the genus chiefly signifies, assumes 
the form of a cup, a form which it does not exhibit. Both of 
these objections lose all their force, however, and become inappli¬ 
cable, if the name is held ho be simply appellative and to apply to 
the whole species, irrespective of the characters originally used 
to establish it. 
Under this view it does not matter whether the different stages 
of development are closely associated as in the case of Uredinopsis 
mirabilis, cited by Magnus, or wholly dissociated as in all 
heteroecious species, of which Puccinia poculiformis is a good 
example. Under this view it would be possible to select the 
generic name, as in the case of the specific name, from all those 
that have been applied to any phase of what is now held to con¬ 
stitute the genus, whether that name was originally applied to an 
imperfect stage, or to what is now believed to be a perfect stage. 
The fact that the generic names of the Uredineae have not yet 
been so adjusted is no reason that they should not be so adjusted. 
Under such a conception of the application of generic and specific 
names, there remains no objection to placing the Uredineae, and 
all other fungi, under the same laws for nomenclature as are 
found serviceable for higher plants. 
I could doubtless make the meaning of my contention more evi¬ 
dent, and the breadth of its application more certain by citing a 
variety of examples, but instead of doing so I will illustrate by 
an analogy that may answer nearly as well and be less tedious. 
There is not much similarity in the names of persons and of 
plants, but as means of identification, which is their chief use, they 
serve the same purpose in each case. If Mr. and Mrs. Gardner 
name their daughter Rose, she continues to bear the name, even 
though in after years it becomes obviously inappropriate. She is.
