Ortegon is endemic to eastern Puerto Rico. It reaches a height of 30 feet, with an erect, cylindrical trunk 5 or more inches in diameter. The leaves are up to 2 feet wide, thick, brittle, and hairless. Fowers are grouped in red inflorescences up to 2.5 feet long, male and female in separate trees. Fruits are egg-shaped and about a quarter of an inch long. It flowers and produces fruits during spring and summer. The generic name derives from an old Greek name for the grape vine. The species name means wrinkled, in reference to the surface of the leaves. Although endemic to Puerto Rico, ortegon was described from specimens cultivated in the 19th century in the Paris Botanical Garden.
