The taste is earthy at first, and then bitter, with a peculiar sweetness. The Bolivian sort is richer in quinine than the Peruvian. Per. Mat. Med., vol. ii., pt. ii., p. 92. A tree of the Bolivian sort is growing in Mr. Howard's conservatory. It is now (1875) 8 feet in height, and differs much in the purple under side of the leaf, and the red veins from the Peruvian sort. (J. E. H.) For fig. of the quills, see Del. et Bouch.
