Notice of tlie !Re-discovery of the Genus Aster antJios, Desf., by 

 Mr. Spruce. By Geoeoe Bentham, Esq., F.L.S. 

 [Read AprH 1st, 1858.] 

 The plant, of which I here exhibit a specimen, has excited much 

 interest, as well from its close relationship to the African Na/po- 

 leona, as from the uncertainty of the origin of the only specimen 

 hitherto known. This specimen, or rather fragment, was part of 

 a herbarium brought from Portugal to the Museum of the Jardin 

 des Plantes of Paris in the commencement of the present century, 

 and which contained, together with several plants from the Brazilian 

 provinces of Pernambuco and Hio Negro, others from Angola in 

 Africa. From this fragment, consisting of a branch with two 

 leaves and a few loose flowers, Turpin made up the figure in the 

 ' Annales du Museum,' and Desfontaines drew up his description. 

 Adrien de Jussieu afterwards dissected one of the loose buds, and 

 as the result showed a great affinity to the Na]poleona and to 

 no other plant known, it was supposed that the Asteranthos also 

 was probably African, but had been misplaced into the Brazilian 

 portion of the above-mentioned herbarium, by some confusion in 

 sorting it, either in Portugal or on its arrival in Paris. Mr. 

 Spruce, however, has now proved that its Brazilian origin was 

 perfectly correct. He found it in great abundance on the banks
