t. 3349. An evergreen, glabrous, unarmed shrub. Leaves oblong-elliptical 

 or almost lanceolate, acuminate, 2 to 3 or rarely 4 in. long, contracted into a 

 short petiole at the base. Flowers terminal, solitary, sessile or nearly so, 

 rather large, white, and sweet-scented. Corolla-tube about 1 in. long, and 

 the narrow-oblong lobes about as much, varying in number from 6 to 8 or 

 rarely 9. Berry oblong, above 1 in. long, crowned by the long linear per- 

 sistent calyx-lobes, and marked outside by as many raised ribs or angles. 



In ravines, Champion and others. It appears also to be really wild as well as cultivated 

 in S. China generally. All the specimens received from other parts are evidently from 

 gardens.

Calyx-limb tubular or campanulate, truncate-toothed or lobed, persistent
