OF PLANTS CALLED COMPOSITE. 283 



may be perhaps expedient to unite them under the name of 

 Grindelia, which was first in order of publication. 



Tridax 



[103 



was first established by Linnaeus, in Hortus Cliffortianus, 

 from a specimen found at Vera Cruz by Houston, and sent 

 to Clifford by Miller. As Linnaeus had no specimen in his 

 own collection, that in Clifford's Herbarium, now in the 

 possession of Sir Joseph Banks, is the only authority for 

 the genus ; and on examining this specimen I find the 

 pappus to be not setaceous, as Linnaeus has described it, 

 but distinctly plumose. There is, therefore, no difference 

 whatever between Tridax and Bcdbisia of Willdenow ; and 

 on comparing Tridax procwnbens with Balbisia elongata, I 

 cannot satisfy myself that they are even specifically dis- 

 tinct. 



Angianthus. 



Angianthus tomentosus of Wendland's Collectio Plan- 

 tarum, (vol. ii, p. 32, tab. 48,) published in 1809, is evi- 

 dently the same plant as my Cassinia aurea, described in 

 the fifth volume of the second edition of Hortus Kewensis, 

 which did not appear till 1813. Wendland neither men- 

 tions the native country of his Angianthus, nor from whence 

 he received it. He must, no doubt, however, have obtained 

 it from Kew Garden, where it was introduced and flowered 

 from seeds which I collected in 1802, in the island of St. 

 Francis, on the South coast of New Holland. 



Meyera. 



This genus, described by Schreber in his edition of the 

 Genera Plantarum, is not adopted by Willdenow. Swartz, 

 however, in his Flora Indiae Occidentalis, has referred to it, 

 and I have no doubt correctly, Eclipta sessilis of his Pro- 

 dromus. On comparing this species of Meyera with a 

 plant in Sir Joseph Banks's Herbarium, collected in Peru
