" The family is very numerous. Persoon's ' Synopsis ' contains 812 

 species, l-26th part of all the plants therein enumerated. In the system 

 of Roomer and Sehultes there are 1800, and since this work, were it 

 brought to a conclusion, would probably contain 40,000 in all, it may 

 be assumed that the grasses form a 22nd part. It is more than 

 probable however that in future the grasses will increase in a larger 

 ratio than the other phanerogamic plauts, and that perhaps the just 

 proportion will be as 1 to 20 or as 1 to 16. Greater still will be their 

 proportion to vegetation in general when the number of individuals 

 is taken into account, for in this, respect the greater number, nay 

 perhaps the whole, of the other classes are inferior. With regard to 

 locality in such a large family, very little can be advanced.
