Trees or shrubs, with aromatic foliage, hard durable wood, and scaly bark. Leaves opposite, 
coriaceous or membranaceous, penniveined, destitute of stipules. Flowers often large and conspicuous, 
white, rose, or rarely straw-colored, bibracteolate. Inflorescence centripetal, the pedicels one-flowered, 
opposite, solitary in the axils of the leaves, fascicled or collected in short racemes; or centrifugal, the 
flowers in dense terminal cymes, or in terminal or lateral trichotomous panicles. Bracts and bractlets 
usually minute, caducous, occasionally foliaceous and persistent. Calyx-tube globose-ovoid, turbinate 
or elongated, sometimes angled or winged, not at all or more or less produced above the ovary, the 
limb four or rarely five-lobed, large, or minute and scarcely developed above the truncate margin of 
the tube. Petals inserted on the slightly thickened margin of the disk lining the calyx-tube, four or 
very rarely five or indefinite, free and spreading or more or less connivent, or connate and deciduous 
in a single piece, or wanting. Stamens indefinite, in many ranks, free or obscurely collected into four 
clusters by a slight union of their bases in the bud; filaments filiform, incurved in the bud ; anthers 
versatile, introrse, attached on the back below the middle, two-celled, the cells usually parallel or rarely 
spreading, opening longitudinally. Ovary two, rarely three-celled ; style simple, filiform, crowned with 
a minute capitate stigma ; ovules many in each cell or two to four, attached to a central placenta, semi- 
anatropous; raphe ventral; micropyle superior. Fruit crowned with the persistent calyx-tube, baccate, 
juicy, sometimes almost drupaceous, or dry with a fibrous outer coat. Seeds one to four, globose or 
variously flattened by mutual pressure ; testa membranaceous or cartilaginous, exalbuminous. Embryo
