Nyctaginaceae

Description: A family of soft-wooded shrubs and small trees with simple, opposite or subopposite leaves that are usually somewhat thick and fleshy. The leaves dry blackish or grayish. The smaller veins are often immersed (i.e., difficult to distinguish). One of the most evident characteristics of this family is the presence of betalain pigments, the bright pink and magenta colors found in beets. The terminal bud usually has a coating of rust-colored fuzz.

Economic uses: Bougainvillea, a sprawling shrub in the Nyctaginaceae, is a popular ornamental in the tropics.


Descripción: Una familia de arbustos y árboles pequeños con madera suave y hojas simples, opuestas o subopuestas, y usualmente levemente suculentas. Las hojas secas son grisáceas o negruzcas. Las venas más pequeñas usualmente son dificiles de ver. Una característica llamativa de esta familia es la presencia de betalaínas, pigmentos que dan orígen a los colores fuertes rosados y violados de las remolachas. El botón terminal de las Nyctaginaceas usualmente lleva vello rojizo.

Usos económicos: El arbusto trepador Bougainvillea es una planta ornamental de gran popularidad en las zonas tropicales.
