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 Summarium, of the classification resulting from the application of Morison's principles to these plants. But, even so, the revelation 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 Sciagraphia, containing an account of a complete system of classification, 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 undoubtedly been influenced by Ray's systematic writings which had appeared meanwhile. It is of such interest that it may be reproduced here, somewhat compressed, with an indication of the modern equivalents of the groups.
