Diclinanona calycina var. macrophylla R.E.Fr. | |
Diclinanona calycina is a species of plant in the family Annonaceae. It is native to Brazil, Colombia, Peru and Venezuela.[2] Ludwig Diels, the German botanist who first formally described the species using the basionym Xylopia calycina, named it after its well-developed calyx (calycinus in Latin).[3]
Description
It is a tree reaching 30 meters in height and 30 centimeters in diameter. Its petioles are 5-15 millimeters long. Its leaves are arranged in two rows. Its elliptical to oval, papery leaves are 10-25 by 3-8 centimeters. The upper surfaces of the leaves are shiny and variably hairless or hairy. The undersides of the leaves have white hairs, particularly along the veins. Its leaves have 14-18 secondary veins emanating from either side of the midrib. Its axillary inflorescences have 2-4 flowers. The flowers are on 6-15 by 0.5-5 millimeter pedicels. Each pedicel has 2 bracts. Its yellow flowers are either male or have both male and female reproductive organs. Its flowers have 3 oval to triangular sepals that are 4-6 millimeters long. The margins of the sepals touch but are not fused and remain attached through fruit maturation. Its flowers have 6 oblong to elliptical petals that are 9-13 by 2.5-3 millimeters. Male flowers have numerous stamens. Bisexual flowers have few stamens and 3-5 carpels. Its round fruit occur in groups of 1-5, are 2.5-3.5 centimeters in diameter, and covered in brown hair. The fruit have 3-8 shiny, brown elliptical seeds that are 1.7-2 centimeters long.[4][5][6]
Reproductive biology
The pollen of D. calycina is shed as permanent tetrads.[7]
Habitat and distribution
It has been observed growing in forest habitats with clay soil.[6]
Uses
Bioactive molecules extracted from its leaves and bark have been reported to have antimicrobial and antiplatelet activity.[8][9]
