Trees or shrubs, infrequently herbs, often with resinous sap. Leaves opposite or verticillate, the stipules small and deciduous or absent, sometimes reduced to glands, the blade simple, entire-margined, penninerved. Inflorescences terminal and axillary, racemose, paniculate or thyrsoid, sometimes flowers axillary and solitary. Flowers X, obliquely zygomorphic, usually bibracteolate; calyx gamo- sepalous, the 5 lobes quincuncial, unequal or rarely subequal, one of the lateral lobes (the fourth one) usually much larger than the other ones and spurred or gibbous at the base; corolla usually perigynously inserted on the calyx, the petals free, rarely 5 and imbricate, usually 1 or 3, unequal and convolute, unguiculate, variously colored; androecium inserted with the corolla, reduced to 1 fertile stamen, the anther introrse, bithecate, longitudinally dehiscent; pollen 3-colporate; stami- nodes often present; gynoecium 3-carpellate, the ovary superior, 3-locular and with 1-oo ovules per cell, rarely ovary almost inferior and I-locular with 1-2 ovules, the placentation axile, the ovules anatropous; style simple, the stigma 1. Fruits usually capsular and loculicidally 3-valvate or infrequently unilocular, indehiscent and enclosed by the accrescent calyx lobes (samaroid); seeds alate, the wing mostly unilateral and consisting of numerous long hairs inserted on the testa, exalbumi- nous; embryo straight; cotyledons mostly convolute.
