Martellidendron hornei (Vakwa Parasol, or Vacoa Parasol) is a species of plant in the Pandan, or Screwpine family (Pandanaceae), one of several Pandanus species that are endemic to the Seychelles.
This species is a tall (15 meters, or 49 feet), erect tree. It has a single, tall, straight trunk, with a spreading, parasol-like canopy only near the top. Its branches usually divide into groups of three. This is not trichotomous, but probably the result of having three ranks of leaves. The multiple fruit is up to twelve inches (30 centimeters) in diameter with large pyrenes. each up to 5.5 inches (14 centimeters) in length, each containing one seed. They are mostly yellow with a green outer tip. [3]
Its stilt-roots are characteristically large but very closely packed.
