 from Garsault's Materia Medica of 1768, in which binomials occur 

 accidentally, and in which the Linnean binomial method is not 

 consistently adopted. 



In Hill's Herbal the genera taken from Tournefort are well 

 defined, the plants are usually well diagnosed, and they are often 

 accompanied by plates ; therefore the accidental binomials in this 

 work are themselves equally eligible for citation. Hill evidently was 

 groping his way to the binomial system, for reference to his work 

 shows that in a large number of cases he had reduced the old unwieldy 

 descriptive names to two or three words. In fact, there are about 

 450 binomials given, but as the trivials are in most cases superseded 

 by those given by Linnaeus in the Species Plantarum of 1753, it 

 has not been thought necessary to cite her% these still-born names. 

 Therefore it is chiefly the valid generic and trivial names which are 

 included in the following list. Some generic names which are avail-
