found in the market at Ambriz, having been used for wrapping up 

 Jinguba, that is, seeds of AracJiis hypogcea^ etc., for transport from 

 the interior ; Nov. 1853. According to the negroes who brought the 

 goods to market, the leaves grew on a tree or bush called " mugi," or 

 " muchi " (these words signify a tree) which occurs in interior elevated 

 forests. No 451&. Leaves used as wrappers for Jinguba seeds, which 

 the negroes carry from the interior of Angola to the markets of the 

 seacoast, towns, etc., and which belong apparently to a large tree, 

 called by the Bunda negroes " Dibala." In damp forests on the north- 

 east confines of the district of Pungo Andongo, in the Ginga kingdom ; 

 leaves seen in Sept. 1857. No. 451c. A tree, apparently small ; trunk 

 straight, beset with crowded slender horizontally spreading spines ; 

 bark whitish grey ; leaves alternate, in the young state enclosed in 

 large stipules ; the blade cordate-ovate, angular, with incumbent basal 

 lobes, narrowed and more or less emarginate-bifid at the apex, about 

 18 in. long and broad ; petioles 1 to 1^ ft. long ; the trunk and 

 branches abounding in a limpid gummy sap. In damp interior forests, 

 collected, by Monteiro, received in 1858. No. 451c/. In Sept. 1857, in

 gigantic leaves from the most interior districts, such as Hungo and 

 Duque de Braganga. No. 451f.
