Native Floras were also objects of very careful investiga- 

 tion during the seventeenth century. 



Jacob Barrelier, a Dominican, a native of Paris, who died 

 1673, had carefully examined the vegetable kingdom through- 

 out the whole of the south of Europe, and made a multitude 

 of discoveries, which were published long after his death, un- 

 der the title Plantae per Galliam, Hispaniam, et Italiam ob- 

 servatas ; Paris 1714, in folio, with 1324 copperplates. His la- 

 bours were rivalled by those of Silvius Paul Boccone, an Ita-

 rum plantarum Siliciae, Oxford 1674, in quarto ; and his Mu-

The Flora of Prussia found an editor in John Lose], pro- 

 fessor at Konigsberg, who died 1656, and whose Flora Prus-

IV. Events preparatory to the Reformation of' Linnoius,

During the time which intervened between Tourncfort and 

 the publication of the Linnaean reformation, the appearance 

 of the latter author was introduced by some learned men. 

 In particular John Henry Burkhard, a physician in Wolfen- 

 buttel, published in an epistle to Leibnitz, which was again 

 edited by Lorenzo Heister 1750, the passing thought, that 

 plants might be divided according to the number of their fila- 

 ments. But, as he almost immediately opposas this idea, he 

 can by no means be considered as properly a predecessor of 

 Linnaeus. 



But the doctrine of the sex of plants, which had been oh- 

 scurely hinted at by Grew, was experim^entally illustrated by 

 Jacob Bobart, and established by John Ray. Rudolph Ja- 

 cob Camerarius, professor at Tubingen, endeavoured circum- 

 stantially to prove it, by observations and experiments, in a
