These Orders might be divided into Genera 

 by the inflorescence, and be greatly increased 

 if more minute forms are taken into account. 

 They coincide very nearly with the Natural Or- 

 ders in the lower series, and aflbrd in the up- 

 per series a very striking additional mean of 

 knowing Orders and Genera ; by far more use- 

 ful in practice than the hidden modes of ger- 

 mination, and embryonic forms.
