Aneilema umbrosum

Native to tropical Africa and tropical America, this perennial herb grows in moist, shaded forests and along drainage channels. Its creeping stems root at the nodes, allowing it to spread along the ground. The small flowers have three unequal white petals, three fertile stamens, and three smaller sterile stamens. Tiny cup-shaped bracts persist around the flower stalks and help distinguish it from similar dayflowers. Small silvery capsules contain four wrinkled seeds. Photographed in Chocó, Ecuador.
