Pentagonia is a genus of over 40 species of plants in the Coffee or Gardenia family (Rubiaceae}.[1] Pentagonia species are native to Central America and northern South America, and grow in moist tropical forests below 900m.[2] The genus was first described by George Bentham in 1845.[3] The genus is noteworthy for its opposite pairs of huge leaves in a variety of shapes including entire, shallowly or deeply lobed, and even pinnate. These leaves can, in the case of a recently discovered species (possibly Pentagonia gomez-lauritoi) be up to four feet (1.2 meters) long not including the six inch (15 cm) petiole, and up to 2.5 feet (76 centimeters) in width.[4]
