The manchineel tree (Hippomane mancinella) is a species of flowering plant in the spurge family (Euphorbiaceae). Its native range stretches from tropical southern North America to northern South America. [4]

Contents

The name manchineel (sometimes spelled manchioneel or manchineal), as well as the specific epithet mancinella, are from Spanish manzanilla ('little apple'), from the superficial resemblance of its fruit and leaves to those of an apple tree. It is also called beach apple. [5]

A present-day Spanish name is manzanilla de la muerte, 'little apple of death'. This refers to the fact that manchineel is one of the most toxic trees in the world: it has milky-white sap that contains numerous toxins and can cause blistering. The sap is present in every part of the tree—bark, leaves, and fruit. [5] [6]

Description

Hippomane mancinella grows up to 15 metres (49 feet) tall. It has reddish-grayish bark, small greenish-yellow flowers, and shiny green leaves. The leaves are simple, alternate, very finely serrated or toothed, and 5–10 centimetres (2–4 inches) long. [7]

Spikes of small greenish flowers are followed by fruits, which are similar in appearance to an apple, are green or greenish-yellow when ripe. The fruit is poisonous, as is every other part of the tree. [7]

Distribution and habitat

Manchineel is native to the Caribbean, the U.S. state of Florida, the Bahamas, Mexico, Central America, and northern South America. [8]

The manchineel tree can be found on coastal beaches and in brackish swamps, where it grows among mangroves. It provides excellent natural windbreaks and its roots stabilize the sand, thus reducing beach erosion. [6]

Conservation

The manchineel tree is listed as an endangered species in Florida. [9]

All parts of the tree contain strong toxins. [10] Its milky white sap contains phorbol and other skin irritants, producing strong allergic contact dermatitis. [11]

Standing beneath the tree during rain will cause blistering of the skin from mere contact with this liquid: even a small drop of rain with the sap in it will cause the skin to blister. Burning the tree may cause ocular injuries if the smoke reaches the eyes. [12] Contact with its milky sap (latex) produces bullous dermatitis, acute keratoconjunctivitis and possibly large corneal epithelial defects. [13]

Although the fruit is potentially fatal if eaten, no such occurrences have been reported in the modern literature. [14] Ingestion can produce severe gastroenteritis with bleeding, shock, and bacterial superinfection, as well as the potential for airway compromise due to edema. [15]

When ingested, the fruit is reportedly "pleasantly sweet" at first, with a subsequent "strange peppery feeling ... gradually progress[ing] to a burning, tearing sensation and tightness of the throat." Symptoms continue to worsen until the patient can "barely swallow solid food because of the excruciating pain and the feeling of a huge obstructing pharyngeal lump." [5]

In some parts of its range, many trees carry a warning sign – for example on Curaçao – while others are marked with a red "X" on the trunk to indicate danger. In the French Antilles the trees are often marked with a painted red band roughly 1 metre (3 ft) above the ground. [16]

Although the plant is toxic to many birds and other animals, the black-spined iguana ( Ctenosaura similis ) is known to eat the fruit and even live among the limbs of the tree. [10]

The tree contains 12-deoxy-5-hydroxyphorbol-6-gamma-7-alpha-oxide, hippomanins, mancinellin, and sapogenin. Phloracetophenone-2,4-dimethylether is present in the leaves, while the fruits possess physostigmine. [17]

A poultice of arrowroot ( Maranta arundinacea ) was used by the Arawak and Taíno as an antidote against such poisons. [18] The Caribs were known to poison the water supply of their enemies with the leaves. [12] Spanish explorer Juan Ponce de León died shortly after an injury incurred in battle with the Calusa in Florida—being struck by an arrow that had been poisoned with manchineel sap. [19]

Uses

Despite the inherent dangers associated with handling it, the tree has been used as a source of wood by Caribbean furniture makers for centuries. It must be cut and left in the sun to dry the sap. [6] To avoid dangerous contact with the poisonous parts, the tree may be burnt at the base to fell it. [20]

Historical accounts

Manchineel trees are often signposted as dangerous. Do not touch the Manchineel!.jpg
Manchineel trees are often signposted as dangerous.

On the fourth, a party of men were sent to cut wood, as the island apparently afforded plenty of that article; amongst other trees they unluckily cut down several of the manchineel, the juice of which getting into their eyes, rendered them blind for several days. [21]

One day being hugely tormented with mosquitoes or gnats, and as yet unacquainted with the nature of this tree, I cut a branch thereof, to serve me instead of a fan, but all my face swelled the next day and filled with blisters, as if it were burnt to such a degree that I was blind for three days. [22]

The Mangeneel Apple has the smell and appearance of an English Apple, but small, grows on large trees, generally along the Seashore. They are rank poison. I am told that one apple is sufficient to kill 20 people. This poison is of such a malignant nature that a single drop of rain or dew that falls from the tree upon your skin will immediately raise a blister. Neither Fruit or Wood is of any use, that I can learn. [23]

<i>Toxicodendron radicans</i> Species of plant

Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is an allergenic flowering plant that occurs in Asia and eastern North America. The species is well known for causing urushiol-induced contact dermatitis, an itchy, irritating, and sometimes painful rash, in most people who touch it. The rash is caused by urushiol, a clear liquid compound in the plant's sap. The species is variable in its appearance and habit, and despite its common name, it is not a true ivy (Hedera), but rather a member of the cashew and pistachio family (Anacardiaceae). T. radicans is commonly eaten by many animals and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed. It is a different species from western poison ivy, T. rydbergii, which has similar effects.

<i>Antiaris</i> Genus of plants

Antiaris toxicaria is a tree in the mulberry and fig family, Moraceae. It is the only species currently recognized in the genus Antiaris. The genus Antiaris was at one time considered to consist of several species, but is now regarded as just one variable species which can be further divided into five subspecies. One significant difference within the species is that the size of the fruit decreases as one travels from Africa to Polynesia. Antiaris has a remarkably wide distribution in tropical regions, occurring in Australia, tropical Asia, tropical Africa, Indonesia, the Philippines, Tonga, and various other tropical islands. Its seeds are spread by various birds and bats, and it is not clear how many of the populations are essentially invasive. The species is of interest as a source of wood, bark cloth, and pharmacological or toxic substances.
