Annona acuminata |
Annona acuminata is a species of plant in the Annonaceae family. It is native to Panama, and Colombia. [2] William Edwin Safford, the American botanist who first formally described the species, named it after the tapering (acuminatus in Latin) tips of its leaves. [3] [4]
It is a tree reaching 5 to 7 meters in height. Its branches have numerous red-brown lenticels. Its oblong, membranous leaves are 6.5-8 by 1.8-2.2 centimeters and smooth on both surfaces. Its leaves taper to a distinctive tip which at its apex is rounded. The leaves have 10-12 pairs of secondary veins emanating from its midrib. Its petioles are 1.5-3 millimeters long. Flowers are solitary on 16-16 millimeter long peduncles. The peduncles, which are extra- axillary, have two distinctive, 2-4 millimeter long bracteoles, one at their base, and one near their middle. Its sepals are partially fused to form a broad-based calyx with three triangular tips. The outside of the calyx is hairy and the inside has stiff rust-colored hairs at its base. Its flowers have numerous 2.5 millimeter long stamens. Its flowers numerous ovaries arranged in a disc, each with a 1.5 millimeter long, club-shaped style. [4] Its round, spiny fruit is 2-2.5 centimeters in diameter. Its yellow seeds are 7-8 millimeters long. [5]
The bright orange-yellow pollen of Annona acuminata is shed as permanent tetrads. [6]
Extracts of bioactive molecules from its tissues have been reported to contain aporphine derivatives. [7]
