For many years this species has been a favourite plant in our 
stoves, to which it was introduced from the Jardin des Plantes 
at Paris. It was always considered an Arabian plant,—an error 
which originated with Jacquin. Nees von Esenbeck, though he 
detected Jacquin’s mistake, added to the confusion by quoting 
Equatorial America as the native country of B. flava. At the 
same time, he remarks that his B. Senegalensis is perhaps the 
origin of the cultivated plant. In this he is certainly correct; 
for, after a careful comparison of Heudelot's Senegal specimens 
with living and dried ones of the garden plant, I can find no 
difference between them. I havé therefore united the two species; 
and adopted Jacquin's very appropriate specific name.
