Hojas alternas, coriáceas o rara vez cartáceas, los márgenes enteros oparcial a completamente dentados; estípulas pequeñas, triangulares o lineares,caducas. Inflorescencias axilares, cimosas o las flores fasciculadas, rara vezracemosas o las flores solitarias; flores hermafroditas o unisexuales, lasplantas polígamas o dioicas; sépalos 4 o 5; pétalos 4 o 5; estambres 4 o 5, muycortos, menos de 1 mm; disco carnoso, 4 o 5-angulado o lobado, intraestaminal;ovario 2 o 3-locular, los óvulos erectos, 1 o 2 por lóculo. Cápsulas esféricasu obovoides, coriáceas, frecuentemente constrictas en la base, la dehiscencialoculicida, dividiéndose en 2 o 3 segmentos patentes o reflexos; semillas 1-6,ariladas, el arilo basal o envolviendo a la semilla. Aprox. 200 spp., 15 enMesoamérica. Trópicos y subtrópicos del mundo.

    Maytenus es un género ampliamente distribuido y ladefinición de especies es con frecuencia complicada debido al traslape decaracteres similares. Las especies mesoamericanas son por lo general árboles oarbustos glabros con flores 5-meras y semillas completamente envueltas en unarilo blanco, rojo o amarillo.

    MAYTENUS Molina

    Arbustos o árboles pequeños, generalmente glabros; plantas polígamas. Hojas persistentes, alternas, a menudo dísticas, aserradas o enteras, coriáceas; estípulas pequeñas, caducas. Inflorescencia una cima solitaria o fasciculada, axilar, flores pequeñas, blancas o amarillentas; cáliz 5-lobado; pétalos 5, redondeados en el ápice; estambres 5, insertados debajo del disco, filamentos alesnados, anteras obovado-cordadas; disco orbicular, margen ondulado; ovario inmerso en el disco y confluente con éste, 1–3-locular, 1 (2) óvulo en cada lóculo, estilo corto y grueso, estigma 2–4-lobado. Fruto capsular, coriáceo, dehiscencia por 2 (3) valvas; semillas 1 (–3), con arilo vistoso.

    Género con ca 200 especies distribuidas en las Américas, Africa, Asia y en el Caribe; 1 especie se encuentran en Nicaragua y otra se espera encontrar. El ejemplar Pipoly 5171, colectado en el Cerro El Hormiguero, Zelaya, a ca 1100 m, con yemas jóvenes, probablemente es otra especie de Maytenus o un Celastrus. Es un arbusto epífito con hojas alternas, ca 5 cm de largo, con dientes callosos y una inflorescencia conspicuamente pedunculada. El material es muy inmaduro para poder situarlo con certeza.
