This handsome little tree is very frequent near Tarapoto, where 
it grows chiefly on the lower hills, in a sandy soil. Its trunk is 
conspicuous among the other trees, from the shining reddish bark, 
which is continually peeling off in broad thin flakes. In this 
respect it quite resembles the Mulatto-tree of the inundated 
shores of the Amazon, which bears in abundance corymbs of small 
white flowers scented like those of the hawthorn, and in struc- 
ture very like those of a Cinchona. The latter tree, called also 
* Capirona" by the Peruvians, but “ Pao mulatto” in Brazil, has 
been proposed by Mr. Bentham as the type of a new genus of 
Cinchones, under the name of Enkylista. Capirona decorticans 
has, however, very slight botanical affinity with Enkylista, and 
stands much nearer to Calycophyllum, from which it is strikingly 
distinguished by the large ribbed flowers, and the much shorter
