natural Family of Vlants called Composiia. 103 



Tridax 



was first established by Linneus, in Hortus Cliffortianus, from 

 a specimen found at Vera Cruz by Houston, and sent to Clif- 

 ford by Miller. As Linneus had no specimen in his own collec- 

 tion, tliat in Clifford's Herbarium, now in the possession of Sir 

 Joseph Banks, is the only authority for the genus; and on ex- 

 amining this specimen I find the pappus to be not setaceous, as 

 Linneus has described it, but distinctly plumose. There is, there- 

 fore, no difference whatever between Tridax and Balbisia of Will- 

 denow ; and on comparing Tridax procumbens with Balbisia elon- 

 gata, I cannot satisfy myself that they are even specifically di- 

 stinct. 



Angianthus. 



Angianllius tomentosiis of Wendland's Collectio Plantarum, 

 (vol. ii. p. 32. tab. 48.) published in 1809, is evidently the same plant 

 as my Cassiuia aiirea, described in the fifth volume of the second 

 edition of Hortus Kewensis, which did not appear till 1813. 

 Wendland neither mentions 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 Prodromus. On comparing this 

 species oi Meyera with a plant in Sir Joseph Banks's Herbarium, 

 collected in Peru by Dombey, and which exactly agrees with
