A shrub or small tree native to tropical South America, it belongs to the Rubiaceae family and grows in wet tropical habitats. Its glossy leaves occur in opposite pairs, and the flowers are grouped near branch tips. Each flower has an exceptionally long, slender white tube ending in narrow, reflexed lobes.
