Leaves scattered, petioled, oval, and smooth ; co- 

 rymbs terminal, viscid, and pubescent. 



A large and very ornamental shrub, sometimes attaining to the 

 altitude of a small tree. Its leaves are evergreen, coriaceous, 

 very smooth, with the under side somewhat palest. Their form 

 is oval, acute, and entire ; their insertion by scattered petioles, 

 on the sides and extremities of the branches. The flowers vary 

 from white to red ; they grow in terminal corymbs, simple or 

 compound with opposite branches, and made up of slender pe- 

 duncles. These are invested with a glutinous pubescence, and 

 supported at base by ovate, acuminate bractes. The calyx is 

 small, five parted, persistent, with oval, acute segments. The 

 corolla is monopetalous, with a cylindrical tube, a spreading 

 disc, and an erect, five cleft margin. At the circumference of 

 the disc, on the inside, are ten depressions or pits, accompanied 

 with corresponding prominences on the outside. In these depres- 

 sions the anthers are found lodged at the time when the flower 

 expands. The stamens grow from the base of the corolla, 

 and bend outwardly so as to lodge their anthers in the cells of the 

 corolla. From this confinement they liberate themselves during 

 the period of flowering and strike against the sides of the stig- 

 ma. The germ is roundish, the style longer than the corolla 

 and declined, the stigma obtuse. Capsule roundish, depressed, 

 five celled and five valved, with numerous small seeds. Woods,
