Schizachyrium condensatum is a species of grass known by the English common names Colombian bluestem,[1] bush beardgrass, and little bluestem, and the Spanish common names aguará ruguay and yerba barbuda.[2] It is native to South America,[3] and it is well known in other places as an introduced species and noxious weed, particularly in Hawaii.[2]
This is a perennial grass growing up to 1.5 meters tall. It branches near the top of the stem, producing a wide, loose inflorescence up to 40 centimeters long.[2]
This grass is very common in the dry woodlands of Hawaii. It competes with native vegetation, displacing it and forming thick monotypic stands. These stands become very flammable and increase the frequency of fire.[2][4] After fire occurs, it is easier for a similarly invasive grass, Melinis minutiflora, to move in, which increases the total nonnative grass cover. S. condensatum then dies back.[4]

Schizachyrium condensatum es una especie de planta herbácea perteneciente a la familia Poaceae.
Es originaria de América del Sur,[2] y es bien conocida en otros lugares como una especie introducida y maleza nociva, particularmente en Hawái.[3]
Esta es una hierba perenne que alcanza un tamaño de hasta 1,5 metros de altura. Se ramifica cerca de la parte superior del tallo, produciendo una gran inflorescencia suelta de hasta 40 centímetros de largo.[3]
Esta hierba es muy común en los bosques secos de Hawái. Compite con la vegetación nativa, desplazándola y formando gradas monotípicas gruesas. Estos soportes se vuelven muy inflamable y aumentan la frecuencia de fuego.[3][4] Después de producirse el fuego, es más fácil para una hierba similar invasiva, Melinis minutiflora, para mudarse, lo que aumenta la cobertura total de la hierba no nativa. S. condensatum luego muere de nuevo.[4]
Schizachyrium condensatum fue descrita por (Kunth) Nees y publicado en Flora Brasiliensis seu Enumeratio Plantarum 2(1): 333–334. 1829.[5]
Schizachyrium nombre genérico que deriva de las palabras griegas schizein (dividir) y achuron (paja), refiriéndose al lema superior.[6]
condensatum: epíteto latíno que significa "denso"[7]
