NOTE ON 

 Dr. PATKICK BROWNE'S Natural History of Jamaica. 



Dr. Patrick Browne published his " Natural Historv of 

 Jamaica " in 1756, three years after the appearance of Linnseus's 

 " Species Plantarum." Browne did not adopt the binomial 

 system of Linnaeus, but quoted as synonyms of his own 

 diagnostic names the diagnoses of the " Species Plantarum." In 

 his own copy of the History, now in the library of the Linnean 

 Society, Linnaeus added the binomial as a marginal note. 



Linnaeus acquired Browne's herbarium in 1758, and has 

 underlined in his copy of the " History " the first letter of those 

 species of which there was a specimen in Browne's herbarium. 

 In some instances these specimens were the foundation of species 

 published by Linnaeus in the " Systema/' edit, 10, 1759, for 

 instance, Cassia viminea ; others represented species which 

 Browne had failed to identify with those in the " Species 

 Plantarum," for instance, C. hijiora. Sometimes a specimen in 

 Browne's herbarium has not been identified by Linnaeus with 

 any diagnosis of Browne, but has been published in the 

 " Systema," for instance, (7. pilosa.
