Maranta

Maranta is a genus of flowering plants in the family Marantaceae, native to tropical Central and South America and the West Indies. Maranta was named for Bartolomeo Maranta, an Italian physician and botanist of the sixteenth century. About 40-50 species are currently recognized. They all have rhizomes and naturally form perennial clumps. The crowded oval, evergreen leaves are undivided with sheathing stalks. The leaves are flat by day and folded up as the day comes to an end, hence the common name "prayer plant" which attaches to the genus and its species - notably M. leuconeura. The flowers are small with three petals and two larger petal-like staminodes....read more on Wikipedia.
