Calyx glandular on the inner surface or with glands between 

 the lobes ; tube short, campanulate, turbinate, or urceolate ; limb 

 small or obsolete, cleft or obscurely toothed, persistent, not accrescent. 

 Flowers white, commonly fragrant, hermaphroditic, axillary, clus- 

 tered, very rarely terminal and solitary; pedicels and peduncles 

 sessile or short, usually with connate bracteoles forming a single or 

 double cupule at the base of the calyx or on the short pedicels or 

 peduncles. Corolla membranous or slightly coriaceous, salver- or 

 funnel-shaped, contorted, glabrous, or villose on the throat; tube 

 short or elongated; limb spreading, 4- to 8-partite; lobes contorted 

 dextrorsely (as seen from the inside in aestivation). Stamens 4 to 

 8, inserted on the corolla-tube, usually near or at the mouth, ex- 

 serted or included, glabrous, often twisted; filaments short, obsolete, 

 or even two-thirds of the length of the anthers; anthers linear, 

 attached at the back (dorsal surface) above the base. Style filiform, 

 2-cleft, glabrous, usually shortly exserted ; lobes linear, spathulate, 

 or tapering. Disk fleshy, glabrous. Ovary 2-celled; ovules soli- 

 tary, subpeltately attached at about the middle of the ovary or 

 rather lower, amphitropous. Berry ellipsoidal, oblong, or sub- 

 globose, dry or fleshy; pyrenes 2 (one sometimes abortive), papery 

 or coriaceous, convex on the back, flat with a narrow but usually 

 deep longitudinal furrow on the face (inner or ventral surface) ; 

 embryo somewhat curved; cotyledons foliaceous; radicle subterete, 

 inferior, longer than the cotyledons; albumen horny. Leaves oppo- 

 site, usually glabrous, decussate, or rarely three-whorled ; stipules 

 interpetiolate, ovate, basally broad or lanceolate, apiculate, acumi- 

 nate, persistent. Evergreen, seldom deciduous, small trees or shrubs.
