Stem: bark often peeling distinctively. Leaf: simple or 0, generally cauline, alternate, opposite whorled , evergreen or deciduous, often leathery, petioled or not; stipules 0. Inflorescence: raceme, panicle, cyme, or flowers 1, terminal or axillary, generally bracted; pedicel often with 2 bractlets. Flower: generally bisexual, generally radial, bell-shaped, cylindric, or urn-shaped; sepals generally 0 , generally free; petals generally 0 , free or fused; stamens , free, filaments rarely appendaged, anthers dehiscing by pores or slits, awns 0 or 2 4 , seemingly abaxial, reduced or elongate, generally curved; nectary generally present at ovary base, generally disk-like; ovary superior or inferior, chambers generally , placentas axile or parietal, ovules many per chamber, style 1, stigma head- to funnel-like or lobed.
