Calyx small, herbaceous ; sepals 5, imbricate, broad, obtuse, alterna- 

 ting with 5 conspicuous glands. Corolla sa-lver-sliaped ; tube cylindric, 

 narrow at the base, then suddenly widened, without scales or calli 

 within, scarcely constricted at the mouth ; lobes broad, obtuse, over- 

 lapping to the right. Stamens inserted below the middle of the 

 corolla-tube ; filaments very short, flattened ; anthers conniving in a 

 cone, included, linear-lanceolate, acuminate, sagittate ; appendages aa 

 long as or longer than the polliniferous part ; tails short ; foot of the 

 connective glabrous above, with a tongue-shaped projection and a 

 tomentose cushion extending to the broad filamental ridge below. Disc 

 0. Ovary syncarpous, more or less imperfectly 2-celled, ovoid, pubes- 

 cent ; style filiform, passing into the flask-shaped shortly apiculate 

 stigma, which exudes glutinous matter attaching it firmly to the foot of 

 the connective ; placentas meeting and even fused in the lower part of 

 the ovary, receding higher up ; ovules numerous, pluriseriate. Fruit 

 follicular (?). — A large climbing shrub. Leaves opposite, remotely 

 nerved, coriaceous ; axillary stipules distinct, acute, resinous inside ;
