Hura crepitans (syn. Hura brasiliensis Wild.), the Sandbox tree, also known as Possumwood and Jabillo, is an evergreen tree of the spurge family (Euphorbiaceae), native to tropical regions of North and South America in Amazon Rainforest. It is recognized by the many dark, pointed spines and smooth brown bark. These spines have caused it to be called Monkey no-climb.
Sandbox trees can grow to 60 metres (200 ft),[1] and the large ovate leaves grow to two feet wide. They are monoecious. The red flowers have no petals. Male flowers grow on long spikes; female flowers are solitary in axils. The fruit is a large capsule with explosive dehiscence. One source states that ripe pods catapult the seeds as far as 100 metres (330 ft).[2] Another source states that seeds are thrown as far as 45 metres (148 ft) from the tree, with a mode at about 30 metres (98 ft).[1] It has also been known as the Dynamite tree, so named for the explosive sound of the ripe fruit as it splits into segments.
This tree prefers wet soil, and partial shade or partial sun to full sun. It is often cultivated for shade.
Fishermen have been said to use the milky, caustic sap from this tree to poison fish. The Caribs made arrow poison from its sap.[3] The wood is used for furniture under the name "hura". Before more modern forms of pens were invented, the trees' unripe seed pods were sawed in half to make decorative pen sandboxes (also called pounce pots), hence the name 'sandbox tree'.
Hura crepitans is an additive to some forms of the hallucinogenic drink Ayahuasca.
