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 smaU 

 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 

 Cinchonese, 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 rihhed floivers, and the much shorter
