It would be superfluous to add any thing to the descrip- 
tion of the plant as given in De Candolle’s Prodromus. A 
figure, however, will not be out of place, since the ori- 
ginal one given by Willdenow is contained in a work which 
is not common in libraries, and besides, must be unsatisfac- 
tory. The synonym of Rondeletia loniceroides, Don, is gee 
on the author’s own authority, that is, after an authentic 
specimen; else it were impossible to guess that a plant 
described with five segments to the corolla, and as many 
stamens, could be the same as one with a four-cleft corolla 
__ and one stamen, which is the case in Usteria.
