Sterculia foetida is a soft wooded tree that can grow up to 35 metres (115 feet) tall. [2] Common names for the plant are the bastard poon tree, Java olive tree, hazel sterculia, wild almond tree, and skunk tree. [2] [3] [4]
The branches of Sterculia foetida are arranged in whorls; they spread horizontally. The tree's bark is smooth and gray. The leaves are placed at the end of branchlets; they have petioles ranging from 12.5 and 23 centimetres (4.9 and 9.1 inches) in length; the blades are palmately compound, containing 7–9 leaflets. The leaflets are elliptical, 100–170 mm long, and shortly petioled. The petioles are the source of the foul smell of the plant. [5] The flowers are arranged in panicles, 10–15 cm (4–6 in) long. The green or purple flowers are large and unisexual as the tree is dioecious (male and female flowers are found on different trees). The pollens are oval in shape, approximately 40 microns in length. The calyx is dull orange and is divided into five sepals, each one 10–13 millimetres (3⁄8–1⁄2 in) long. The fruit consists of four to five follicles, each follicle generally containing 10–15 seeds. The follicles are scarlet when ripe. [5] In India, flowers appear in March, and the leaves appear between March and April. At Hyderabad (India), flowering was observed in September–October (2015) with ripened fruits on the top part and young green fruits at the lower branches. The fruit is ripe in February (11 months after the flowers appeared). [5]
The species was described in 1753 by Carl Linnaeus. [6] It is the type species of the genus Sterculia and both names mean bad-smelling: the name Sterculia comes from Sterquilinus, the Roman god of fertilizer or manure.
Sterculia foetida has been found in many areas, including India,Bangladesh,Taiwan, Indochina, the Philippines (where it is known as kalumpang), [7] United States (Hawaii), Indonesia, Ghana, Australia, Mozambique, and Togo. [8]
The oil of Sterculia foetida has been found to be comparable to sunflower, soybean, and grapeseed oils for the use of biofuels. Sterculia foetida oil contains cyclopropene fatty acids (CPFA) such as 8,9 methylene-heptadec-8-enoic acid (malvalic acid) and 9,10-methylene-ocadec-9-enoic acid (sterculic acid). The flash point, iodine value, free fatty acid count, phosphorus content, cloud point, pour point, viscosity at 40 °C, oxidative stability at 110 °C, density, and trace metal count are all within ASTM and EN specifications. [9]
Evidence suggests that the seeds are edible, but purgative, [4] and should be roasted prior to eating. [10] At least one review indicates that CPFA such as sterculic acid are carcinogenic, co-carcinogenic, and have medical and other effects on animals; [11] according to this review, "CPFA in food is dangerous to human health".
In Vietnam, the tree is called Trôm and its sap is harvested to use as a soft drink called "Mủ Trôm".
Breadfruit is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to be a domesticated descendant of Artocarpus camansi originating in New Guinea, the Maluku Islands, and the Philippines. It was initially spread to Oceania via the Austronesian expansion. It was further spread to other tropical regions of the world during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in some 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor.
The papaya, papaw, or pawpaw is the plant species Carica papaya, one of the 21 accepted species in the genus Carica of the family Caricaceae. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. It is grown in several countries in regions with a tropical climate. In 2022, India produced 38% of the world's supply of papayas.
Passiflora foetida is a species of passion flower that is native to the southwestern United States, Mexico, the Caribbean, Central America, and much of South America. It has been introduced to tropical regions around the world, such as Southeast Asia, South Asia, Hawaii, Africa, and The Maldives. It is a creeping vine like other members of the genus, and yields an edible fruit. The specific epithet, foetida, means "stinking" in Latin and refers to the strong aroma emitted by damaged foliage.
Mammea americana, commonly known as mammee, mammee apple, mamey, mamey apple, Santo Domingo apricot, tropical apricot, or South American apricot, is an evergreen tree of the family Calophyllaceae, whose fruit is edible. It has also been classified as belonging to the family Guttiferae Juss. (1789), which would make it a relative of the mangosteen.
Averrhoa carambola is a species of tree in the family Oxalidaceae native to tropical Southeast Asia; it has a number of common names, including carambola, star fruit and five-corner. It is a small tree or shrub that grows 5 to 12 m tall, with rose to red-purple flowers. The flowers are small and bell-shaped, with five petals that have whitish edges. The flowers are often produced year round under tropical conditions. The tree is cultivated in tropical and semitropical regions for its edible fruits.
Attalea maripa, commonly called maripa palm is a palm native to tropical South America and Trinidad and Tobago. It grows up 35 m (115 ft) tall and can have leaves or fronds 10–12 m (33–39 ft) long. This plant has a yellow edible fruit which is oblong ovoid and cream. An edible oil can be extracted from the pulp of the fruit and from the kernel of the seed.
Sterculia is a genus of flowering plants in the mallow family, Malvaceae: subfamily Sterculioideae. Members of the genus are colloquially known as tropical chestnuts. Sterculia may be monoecious or dioecious, and its flowers unisexual or bisexual.
Sterculia quadrifida, also known as the peanut tree, monkey nut or red-fruited kurrajong is a small tree that grows in the rainforests, vine thickets, and gallery forests of New Guinea and northern Australia.
Pachira aquatica is a tropical wetland tree in the mallow family Malvaceae, native to Central and South America where it grows in swamps. It is known by its common names Malabar chestnut, French peanut, Guiana chestnut, Provision tree, Saba nut, Monguba (Brazil), Pumpo (Guatemala) and is commercially sold under the names Money tree and Money plant. This tree is sometimes sold with a braided trunk and is commonly grown as a houseplant, although more commonly what is sold as a "Pachira aquatica" houseplant is in fact a similar species, P. glabra.
Cyclopropane fatty acids (CPA) are a subgroup of fatty acids that contain a cyclopropane group. Although they are usually rare, the seed oil from lychee contains nearly 40% CPAs in the form of triglycerides.
