This cinchona readies a height of thirty to Forty-five feet and above. The trunk is mostly single, but sometimes two or three grow from one root, which separate from each other as they ascend, or have alike a horizontal direction. But if there is only one stem it rises perpendicularly aloft. Its thickness is from one and a half to five and a half feet. It bears many upright branches, which produce very thick boughs.

Von Bergen, agrees (except a few pieces of micrantha') with this species, and perhaps h...
