MORISON'S METHOD 23 



should have died without having published any more definite 

 information concerning his system of classification than what 

 has been here cited. 



Morison's influence did not, however, cease with his death ; 

 his tradition was maintained by the publication in 1699 of the 

 Pars Tertia of the Historia, under the editorship of Bobart. 

 This volume threw some welcome light upon Morison's system, 

 inasmuch as it completed the description of the herbaceous 

 plants, and gave a clear statement, in the form of a Botanologiae 

 Siimmariiivi, of the classification resulting from the application 

 of Morison's principles to these plants. But, even so, the revela- 

 tion of the system still remained incomplete, in the absence of 

 any account of the trees and shrubs. 



It was not till nearly forty years after Morison's death, not 

 until Bobart too was dead, that a full statement of Morison's 

 method was published. In 1720 there appeared at Oxford a 

 small tract of but twelve pages, the Historiae Naturalis Scia- 

 graphia, containing an account of a complete system of classifi- 

 cation, which agrees in all essentials, so far as herbaceous plants 

 are concerned with that adopted by Morison and by Bobart in 

 their respective volumes of the Historia : and, as regards trees 

 and shrubs, with that in the MS. volume by Bobart which has 

 been already mentioned. The tract is anonymous, but the 

 matter that it contains is Bobart's work, whether it was written 

 by himself or by some one who had access to his papers. This 

 classification may be accepted as being essentially that of 

 Morison, though somewhat modified by Bobart, who had un- 

 doubtedly been influenced by Ray's systematic writings which 

 had appeared meanwhile. It is of such interest that it may be 

 reproduced here, somev/hat compressed, with an indication of 

 the modern equivalents of the groups.
