Hura crepitans, the sandbox tree,[1] also known as possumwood, monkey no-climb, assacu (from Tupi asaku) and jabillo,[2] is an evergreen tree in the family Euphorbiaceae, native to tropical regions of North and South America including the Amazon rainforest. It is also present in parts of Tanzania, where it is considered an invasive species.[3] Because its fruits explode when ripe, it has also received the colloquial nickname the dynamite tree.[4][5]
Description
The sandbox tree can grow to Шаблон:Convert,[6] and its large ovate leaves grow to Шаблон:Convert wide. They are monoecious, with red, un-petaled flowers. Male flowers grow on long spikes, while female flowers grow alone in leaf axils. The trunk is covered in long, sharp spikes that secrete poisonous sap. The sandbox tree's fruits are large, pumpkin-shaped capsules, Шаблон:Convert long, Шаблон:Convert diameter, with 16 carpels arranged radially. Its seeds are flattened and about Шаблон:Convert diameter. The capsules explode when ripe, splitting into segments and launching seeds at Шаблон:Convert.[4] One source states that ripe capsules catapult their seeds as far as Шаблон:Convert.[7] Another source states that seeds are thrown as far as Шаблон:Convert from a tree, averaging about Шаблон:Convert.[6]
Habitat
This tree prefers wet soil, and partial shade or partial to full sun. It is often cultivated for shade. Sandbox trees are tropical trees and prefer warmer, more humid environments.
Uses
Its wood is light enough to make indigenous canoes.[8] Fishermen have been said to use the milky, caustic sap from this tree to poison fish.[9] The Caribs made arrow poison from its sap.[10] The wood is used for furniture under the name "hura". Before more modern forms of pens were invented, the trees' unripe seed capsules were sawn in half to make decorative pen sandboxes (also called pounce pots), hence the name 'sandbox tree'. It has been documented as a herbal remedy.[11]
The seeds contain an oil that is toxic for consumption but can be made into biodiesel and soap; its starchy leftovers can be made into animal feed after cooking.[8]
