EXPLANATION OF TABLE 



The appended table attempts to give a r6sum6 of the development 

 of the science of Botany in phylogenctic form. It must be 

 clearly understood, however, that the names selected are merely 

 representative, and are not to be taken as exclusive of others 

 holding similar views and, possibly, of equal merit. When the 

 same name occurs twice on the same phylum or on two different 

 phyla the intention is to indicate that the author quoted was 

 instrumental in advancing the science in more than one aspect. 

 Thus, Brongniart's name is associated chiefly, perhaps, with 

 important additions to our knowledge of fossil plants, but he 

 also formulated a classification of the vegetable kingdom which 

 must be taken into consideration in any outline of the development 

 of the subject of taxonomy. Again, Bower's name appears twice 

 on the " Cryptogamic " phylum ; the earlier entry refers to 

 his monographs on " Spore-producing members," the later to 

 his " Origin of a Land Flora." Save in the very earliest entries, 

 the dates are approximate only, and suggest the period rather 

 than the exact year of publication of important contributions ; 

 in no case do they indicate the date of birth or of death of the 

 author quoted. If more space were available the table might 

 be extended, almost indefinitely, but for the ordinary student's 

 purposes it is considered that the selection may suffice to provide 

 landmarks in botanical history.
