Mosquitoxylum Krug & Urb.

Polygamodioecious (androdioecious) trees. Leaves evergreen (more or less), alternate, imparipinnate; leaflets opposite or subopposite, short-petiolulate, entire. Inflorescences terminal and/or axillary panicles with spicate branches. Flowers sessile or short-pedicellate, each subtended by 3 deltoid bracts; perianth 5-parted, imbricate; corolla greenish white, or cream-colored; androecium haplostemonous; pistillode reduced; staminodes in female flower very reduced; disk glabrous, 5-lobed; carpels 3; style short, distally 3-branched, excentric; stigmas 3; ovule sublateral. Drupe obliquely ovoid, compressed, 1-locular; exocarp red, glabrous.

A single species, M. jamaicense, southern Mexico south to northwestern Ecuador and Jamaica. Morphological and molecular evidence suggests that Mosquitoxylum is closely related to Rhus.
