Since the appearance of Prof. T. C. Porter’s estimable Flora of 
Pennsylvania in 1903, discoveries of indigenous species heretofore 
unknown in the region have not been so overwhelmingly numerous 
that they are without a certain interest. Some index of the almost 
exhaustive exploration which Prof. Porter and his associates succeeded 
in achieving over an area of really very considerable size and diversity 
is shown by the fact that only about one in ten of the additions in 
recent years is an indigenous species which was well known in Porter’s 
day. For it will be remembered that in the numerical count of species 
there are two main sources of so-called “additions” to the flora of 
any well known area: new introductions and species due to work of 
more recent revision and segregation. In these two categories are 
unquestionably included the great majority of species (now known to 
occur in the state) which are not recognized in Porter’s Flora. 
As a further suggestion of the completeness of Porter’s Pennsyl- 
vania collection may be noted the fact that it contains an excellent 
representation of species recently described or ones only lately recog- 
nized as elements of our flora. Thus, for example, there is ample 
material from the state of Echinochloa muricata, Muhlenbergia foliosa,
