    • TOURNEFORTIA L.

      Arboles pequeños, arbustos o trepadoras leñosas. Hojas alternas u opuestas, enteras, pecioladas o raramente sésiles. Inflorescencias cimas esparcidas a marcadamente ramificadas, densas a laxas, terminales o internodales; sépalos 5, generalmente uno de ellos excediendo a los demás en longitud, persistentes; corola blanca a verde o amarillo-verdosa, de forma tubular con 5 lobos patentes; estambres 5, anteras generalmente sésiles o casi sésiles, dispuestas en la parte interna del tubo de la corola; ovario ovoide a globoso, 4-locular, estilo terminal o ausente. Frutos drupáceos, frecuentemente blancos al madurarse, más tarde separados en 2 ó 4 nuececillas óseas.

      Un género con unas 150 especies de regiones tropicales y subtropicales; 10 especies en Nicaragua, lo cual es un número relativamente bajo para Centroamérica, ya que muchas especies alcanzan su limite sur de distribución al norte de Nicaragua. Muchas especies se encuentran en hábitats mesofíticos y plantas individuales pueden encontrarse en flor o fruto durante todo el año.
