Those parts of the stems and branches more or less covered with 

 débris bear rather numerous roots, while attached to the stem is an 

 irregularly ovoid woody growth resembling the underground thickened 

 parts of certain epiphytic or semi-epiphytic Melastomataceae. The 

 branching is largely beneath the covering débris, the tips of the branches 

 protruding and bearing the apical leaves and the latéral flowers. The 

 species seems to be allied to Agapetes oblonga Craib of Yunnan, differ- 

 ing in its leaves being crowded at the very tips of the branchlets, in its 

 latéral not a.xillary fîowers, which are hirsute, the spreading hairs on the 

 pedicels, calyx and corolla being more or less capitate-glandular.
