All the forms of this genus, being connected by continuous links, are here united 
into one species ; they vary much in the degree of pubescence, the original R. febrifuga 
being nearly glabrous. The bark is employed as a febrifuge. Native names at 
Sierra Leone, “ béllenda” and bémbee (Winterbottom, /. c.). For an account of the 
medicinal virtues of this plant, called African bark, see Winterbottom, J. c., p. 243.
