A small natural order of trees, often gigantic, with copious, resinous juice, rarely erect, sarmentose, or climbing shrubs, confined to tropical America. Flowers irregular, hermaphrodite, often large; sepals five, free or connate at base, or rarely adnate to the ovary, the two outer ones often smaller, the two anterior larger, the posterior often largest, spurred or gibbous at base; petals hypogynous, or inserted on the top of the calyx tube, one, three, or rarely five, when one is protruded between the blade of the anterior sepals, clawed; stamens inserted with the petals, usually fertile, the rest imperfect; filaments usually thick, excrescent, subulate; pedicels jointed and bracteate; inflorescence variable. Fruit usually capsular, rarely a winged samara. Leaves opposite, whorled, or alternate, shortly petiolate, coriaceous, quite entire; stipules small, reduced to glands, or wanting. Branches usually opposite or whorled. The order embraces seven genera, and about 100 species. Examples: Qualea, Trigonia, Vochysia.
