Notice of the Re-discovery of the Genus Asteranthos, Desf., by 
Mr. Spruce. By Groner Bentuiy, Esq., F.L.S. 
[Read April 1st, 1858.] 
Tux plant, of which I here exhibit a specimen, has excited much 
interest, as well from its close relationship to the African Napo- 
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 Rio 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 Muséum,’ 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 Napoleona 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
