Memorials of Linn<zus 



Linnaeus was able to visit England in 1736. The herbarium 

 was bought by Sir Joseph Banks in 1791 and passed with the 

 other Banksian collections to the British Museum. 



WORKS OF LINN^US 



1 SYSTEMA NATURE. Published at Leyden,' 1735. One 

 of the earliest works of Linnaeus and a very rare book. It 

 consists of eight large sheets in the form of tables, and is a 

 systematic grouping of the three kingdoms of Nature, Minerals, 

 Plants, Animals. Linnaeus's division of plants into twenty- 

 four Classes, determined mainly by the number or some other 

 obvious character of the stamens, is known as the Sexual 

 System. 



PLATE ILLUSTRATING THE SEXUAL SYSTEM, by Georg 

 Dionysius Ehret (1708-1770), Leyden, 1736. The coloured 

 drawing shown is the original of a plate illustrating the Classes 

 of the Sexual System, which was published separately by Ehret 

 and afterwards reproduced by Linnaeus in the Genera Plantarum 

 (1737). Ehret became acquainted with Linnaeus at Clifford's 

 house ; some of the plates in the Hortus Cliffbrtianus are from 

 his drawings. 



2 GENERA PLANTARUM. Published at Leyden, 1737. A 

 definition and description of all the genera of plants then 

 known. 



3 SPECIES PLANTARUM. Published at Stockholm, 1753. 

 A definition and description of all the species of plants then 

 known, and the starting-point of modern botanical nomenclature. 



Perhaps the most important service rendered to science by 

 Linnaeus was the establishment of a binary system of nomen- 

 clature in which every species of plant and animal is designated 

 by two words, e.g., Rosa canina the first, Rosa, the name of 

 the genus to which it belongs, and the second, canina^ the 

 specific or trivial name which distinguishes it from other species 

 of the genus. 



The volume is from Linnaeus's library and contains notes 

 in his hand.
