Hymenaea stiginocarpa is an irregularly shaped, mostly 6–9 m (20–30 ft) high tree that has been assigned to the pea family. It has a twisted spindle-shaped trunk, a very rough grey bark, and reddish-brown twigs. The deciduous leaves consist of two large asymmetrical leaflets with an entire margin. The flowers occur in clusters of up to thirty at the end of the branches. It produces edible, highly appreciated fruits, which are often collected from the wild and used by local people. The vernacular name of this species in Brazil is jatobá do cerrado. [2] [3]
Friedrich Gottlob Hayne, a German botanist, first scientifically described this species in 1830 as Hymenaea stigonocarpa, a name that had been used before by Carl Friedrich Philipp von Martius, and was based on a specimen collected from a seasonally dry forest type, locally known as Caatinga, in the state of Piauí, north-eastern Brazil, during his 1817-1820 expedition. In 1870 however, George Bentham applied the name to specimens collected in the Cerrado of Central Brazil, and the name has since been used in association with specimens from the Cerrado. In addition he created the subspecies pubescens. João Barbosa Rodrigues, one of the most famous Brazilian botanists, in 1898 distinguished H. chapadensis, as well as H. correana, both of which were later considered synonyms of H. stigononcarpa subsp. pubescens. In 1925, Adolpho Ducke assigned the name Hymenaea velutina to specimens collected in north-eastern Brazil, which also became widely used for specimens from Caatinga. Recently, it has been established that the original material used to describe H. stigonocarpa belongs to the same species as the type of H. velutina. It has now been proposed to conserve the name H. velutina over H. stigonocarpaHayne, and to continue applying H. stigonocarpa to the species from the Cerrado as used by Bentham. [4] [5]
Hymenaea stigonocarpa has twenty four chromosomes (2n=24). [6] It is a low to medium height deciduous tree of 5–20 m (16–66 ft) and a diameter of up to 50 cm (20 in) at breast height. It has a twisted trunk covered by a thick rough grey bark and reddish-brown twigs. Its leaves are alternately set, and consist of two leathery, kidney-shaped to ovate leaflets of 6–24 cm (2.4–9.4 in) long and 3.5–7 cm (1.4–2.8 in) wide, with quickly falling bracts (so-called stipules) at their base. The flowers of this species are the largest in the genus, and the petals are somewhat larger than the sepals. The five sepals are thick and are deflected when the flowers have opened. The five white petals are approximately 22 mm (0.87 in) long and 12 mm (0.47 in) wide and are set on the edge of a broad hypanthium. Ten free, white, 40 mm (1.6 in) long filaments are tipped by 9 mm (0.35 in) long anthers. In the middle of the hypanthium is a single, fleshy carpel on a short, 6–8 mm (0.24–0.31 in) long stalk, which is tipped by a long curved white style implanted at an angle, with a bud-shaped wet grainy stigma at the tip. Up to thirty flowers are set in inflorescences at the tip of the branches, subtended by bracts. The species depends on cross-pollination and is pollinated mainly by bats. Self-fertilised flowers are aborted after a week. The ripe fruit is light to dark brown with small and regularly spaced light glands, dry, indehiscent, leathery legume of 9–20 cm (3.5–7.9 in) long, 2–6.5 cm (0.79–2.56 in) wide and 2–4.3 cm (0.79–1.69 in) thick, with a rounded base, a slightly pointed tip, and a straight or wavy margin. The mesocarp and endocarp have been transformed into yellowish, soft, fibrous, slightly sweet flour-rich pulp with a characteristic smell. A prominent suture line surrounds the entire legume. Fruits are ripe between April and July in the Federal District, July to November in Mato Grosso do Sul and August in Minas Gerais. It contains one to six seeds. These seeds are redish-brown, oval, side-ways compressed, 18–28 mm (0.71–1.10 in) long and 9–20 mm (0.35–0.79 in) thick, with rounded tip and base, an irregular surface and some depressions. [3] [7] [8] [9] Overly ripe fruits emit an unpleasant smell. [10]
The nectar-rich flowers of Hymenaea stiginocarpa open at night and are pollinated by several bat species, among which are the mostly fruit-eating Platyrhinus lineatus and Carollia perspicilata and the nectar specialist Glossophaga soricina . Hawkmoths also frequent the flowers, but seem ineffective in pollinating them. Self-pollinated seeds do not fully mature. Although the flower’s own pollen grains grow tubes and fertilise ovules as successfully as pollen from a different specimen, after seven or eight days the self-pollinated fruits fall from the tree. The mechanism to abort self-pollinated fruits is not known, but cross-fertilised ovules grow faster from the start. [9]
By producing annually large amounts of fruits that are consumed by terrestrial fauna, the species also plays an important ecological role. [7] It has been suggested that the agouti is responsible for most of the seed dispersal of H. stigonocarpa. [11]
Unlike many other species of the family Fabaceae, Hymenaea stiginocarpa is said to lack symbiontic soil bacteria, and therefore is unable to directly use the nitrate made by the bacteria from atmospheric nitrogen. [2]
Hymenaea stiginocarpa occurs in northern, central, and eastern Brazil and in Paraguay. [2]
Jatobá do cerrado is an important tree for the people of the Brazilian Cerrado, and it represents a substantial economic value with its high quality wood, resin and edible fruits. These fruits can be used to produce flour and in the preparation of different types of food. With the increasing demand for the products of this plant, there is a need for commercial cultivation and for growing high quality seedlings. [12]
Jatobá fruit pulp contains about 5½% protein, and almost 50% high-fibre flour consisting of 40% non-soluble fibre and about 9% soluble fibre. [13]

The flour made from jatobá is appreciated by the local people in the Cerrado and used to prepare jelly, liqueur, cakes, breads and porridge. [7] The resin from the stems of jatobá do cerrado is used to polish canoes, and to produce varnishes. [15]
Scholars showed a large variation in genetics between and within subpopulations that corresponds to variability in the weight of the fruit, and this provides perspective for breeding varieties with more favourable traits for human use. [7] Seedlings can be grown in plastic bags with 50% shading, and do best in a mineral soil without organic compost and in a greenhouse. [12] H. stigonocarpa grows best in a sunny spot and prefers well-drained soil. When established, the trees are somewhat resistant to drought. In general, it grows slowly. [2] Jatobá do cerrado is sometimes planted as an ornamental. [2]
One study showed that extracts of H. stigonocarpa suppressed cell division in onions, and this may imply that it contains some cytotoxic substance. [16]
The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulate leaves. The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae, with about 765 genera and nearly 20,000 known species.
Cercis is a genus of about 10 species in the subfamily Cercidoideae of the pea family Fabaceae. It contains small deciduous trees or large shrubs commonly known as redbuds in the USA. They are characterised by simple, rounded to heart-shaped leaves and pinkish-red flowers borne in the early spring on bare leafless shoots, on both branches and trunk ("cauliflory"). The genus contains ten species, native to warm temperate regions of North America, southern Europe, western and central Asia, and China.
Enterolobium cyclocarpum, commonly known as conacaste, guanacaste, caro caro, devil's ear tree, monkey-ear tree, or elephant-ear tree, is a species of flowering tree in the family Fabaceae, that is native to tropical regions of the Americas, from central Mexico south to northern Brazil (Roraima) and Venezuela. It is known for its large proportions, expansive, often spherical crown, and curiously shaped seedpods. The abundance of this tree, especially in Guanacaste Province, Costa Rica, where it is prized for the shady relief it provides from the intense sun, coupled with its immensity, have made it a widely recognized species. It is the national tree of Costa Rica.
The cherimoya, also spelled chirimoya and called chirimuya by the Quechua people, is a species of edible fruit-bearing plant in the genus Annona, from the family Annonaceae, which includes the closely related sweetsop and soursop. The plant has long been believed to be native to Ecuador and Peru, with cultivation practised in the Andes and Central America, although a recent hypothesis postulates Central America as the origin instead, because many of the plant's wild relatives occur in this area.
Ficus citrifolia, also known as the shortleaf fig, giant bearded fig, Jagüey, wild banyantree and Wimba tree, is a species of banyan native to southern Florida, the Caribbean, Mexico, Central America, and northern South America south to Paraguay. It is distinguished from the closely related Florida strangler fig mainly by the finer veining in the leaves.
Couroupita guianensis, known by a variety of common names including cannonball tree, is a deciduous tree in the flowering plant family Lecythidaceae. It is native to the tropical forests of Central and South America, and it is cultivated in many other tropical areas throughout the world because of its fragrant flowers and large fruits, which are brownish grey. There are potential medicinal uses for many parts of Couroupita guianensis, and the tree has cultural and religious significance in South and Southeast Asia. In Sri Lanka and India, the cannonball tree has been widely misidentified as the Sal tree, after its introduction to the island by the British in 1881, and has been included as a common item in Buddhist temples as a result.
Solanum lycocarpum, or wolf apple, is common in the Brazilian savanna, the Cerrado ecoregion. The plant is called lobeira or fruta-do-lobo in Portuguese.
Hymenaea is a genus of plants in the legume family Fabaceae. Of the fourteen living species in the genus, all but one are native to the tropics of the Americas, with one additional species on the east coast of Africa. Some authors place the African species in a separate monotypic genus, Trachylobium. In the Neotropics, Hymenaea is distributed through the Caribbean islands, and from southern Mexico to Brazil. Linnaeus named the genus in 1753 in Species Plantarum for Hymenaios, the Greek god of marriage ceremonies. The name is a reference to the paired leaflets.
Dekeyser's nectar bat is a bat species found in Brazil and Bolivia.
Annona coriacea is a fruit tree native to Brazil. Its original habitat includes the ecoregions of Cerrado, Caatinga, and Pantanal. There, it is typically found in scrublands and savannahs, though it is sometimes grown in orchards. Its wood is used in constructions and toys. This plant is cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius.
