Pisonia grandis, the grand devil's-claws,{{PLANTS|id=PIGR6|taxon=Pisonia grandis|accessdate=6 October 2015}} is a species of flowering tree in the Bougainvillea family, Nyctaginaceae.

Description

The tree has broad, thin leaves, smooth bark and bears clusters of green sweet-smelling flowers that mature into sticky barbed seeds.

Dispersal occurs when seeds stick to bird feathers. Vegetative reproduction frequently results when fallen branches sprout or basal shoots develop into new trees.

Distribution

Pisonia trees are distributed throughout the coral cays of the Indian and Pacific Oceans. The species often dominates mature coral cay vegetation, growing in dense, thick strands up to {{convert|20|m|ft|abbr=on}} tall. Pisonia wood is rather weak and soft and decays rapidly when the trees fall.

Pisonia forests are a common nesting site for seabirds. One of the best remaining Pisonia forests can be found on Palmyra Atoll.

St. Pierre Island, Farquhar Group, was once covered by a Pisonia grandis forest. This forest disappeared after guano mining between 1906 and 1972. The natural vegetation was destroyed in order to scrape the guano and the island's landscape became barren.{{aut|Piggott, C.J.}} (1961): Notes on some of the Seychelles Islands, Indian Ocean.
