Annona nutans is a species of plant in the family Annonaceae. It is native to Argentina, Bolivia, Brazil and Paraguay. [3] Robert Elias Fries, the Swedish botanist who first formally described the species, named it after its recurved peduncles which give the flowers a nodding (nutans in Latin) appearance. [4] [5]
It is a bush 5 to 6 meters (16 to 20 ft) in height. Its branches have inconspicuous, brown lenticels. Its membranous, oval leaves are 3–5 by 2.5–3.2 centimeters with rounded apex that ends in an abrupt small point. The leaves are hairless on their upper surface and on their lower surface except along the midrib and veins when young. The leaves have 10 secondary veins emanating from each side of the midrib. Its petioles 2 millimeters long and have a groove on their upper side. Its recurved peduncles are 2.5–4 centimeters long, extra-axillary and usually emerge opposite a leaf. The peduncles are solitary or in pairs. The peduncles have a bract, covered in rust colored hairs, at their base and another at their midpoint. Its sepals are united to form a calyx with triangular lobes that come to a point. The outer surface of the calyx is covered in rust-colored silky hairs. Its petals are united to form a corolla, 1.5–2.3 centimeters in diameter, consisting of 3 broad lobes alternating with 3 narrow lobes. The outer surface of the corolla is covered in fine rust-colored hairs. The corolla is yellow to ochre-colored with purple spots on the inside. Its stamen are 1.8–2.2 millimeters long with flat filaments. The connective tissue between the lobes of the anther is extended to form a cap. Its flowers have multiple carpels that form a cone-shaped gynoecium. Its 4-sided, prism-shaped ovaries are 0.9–1 millimeters long. Its fleshy, quadrangular styles are 0.9–1 millimeters long and terminate in ovoid stigmas. The outermost styles are covered in fine glandular hairs. The mature orange fruit are 5 centimeters in diameter and 7 centimeters long. [6] [5] [7]
The pollen of Annona nutans is shed as permanent tetrads. [8]
It has been observed growing in fields, sandy plains and valleys. [6]
It was described as being edible in 1914 by the American botanist William Edwin Safford. [7] The pulp of the wild, fresh fruit has been reported as being used as a food source in Brazil. [9]
Annona sericea is a species of plant in the family Annonaceae. It is native to Bolivia, Brazil, Colombia, French Guiana, Guyana, Suriname, Trinidad-Tobago and Venezuela. Michel Félix Dunal, the French botanist who first formally described the species, named it after the silky hairs on its branches and leaves. In Brazil its common name is Aratincum do Para.
Annona acuminata is a species of plant in the Annonaceae family. It is native to Panama, and Colombia. William Edwin Safford, the American botanist who first formally described the species, named it after the tapering tips of its leaves.
Annona acutiflora is a species of plant in the Annonaceae family. It is native to Brazil. Carl Friedrich Philipp von Martius, the German botanist who first formally described the species, named it after the inner petals which come to a sharp point.
Annona angustifolia is a species of plant in the Annonaceae family. It is native to Brazil. Jacques Huber, the Swiss-Brazilian botanist who first formally described the species, named it after its narrow leaves.
Annona bullata is a species of plant in the family Annonaceae. It is native to Cuba. Achille Richard, the French botanist who first formally described the species, named it after the bubbled appearance of the spaces between the fine network of veins in the leaves.
Annona cascarilloides is a species of plant in the Annonaceae family. It is endemic to Cuba. According to William Edwin Safford, the species was named it after the pattern of its leaf veins which resemble species of a different genus, that at the time Safford was writing was called Cascarilla, but is now synonymous with the genera Croton and Ladenbergia. Despite this assertion by Safford, August Grisebach, the German botanist who first formally described the species, makes no mention of Cascarilla in his 1866 entry.
Annona crassivenia is a species of plant in the family Annonaceae. It is native to Cuba. William Edwin Safford, the American botanist who first formally described the species, named it after the thick tertiary veins that interconnect the secondary veins of its leaves.
Annona dioica is a species of plant in the family Annonaceae. It is native to Bolivia, Brazil and Paraguay. Augustin Saint-Hilaire, the French botanist who first formally described the species, named it after its flowers which have different reproductive structures and.

Achille Richard, the French botanist who first formally described the species, using the basionym Uvaria monopetala, named it after its petals which are fused at their base.
