Annona haitiensis is a species of plant in the Annonaceae family. It is endemic to the Caribbean island of Hispaniola.[1] Robert Elias Fries, the Swedish botanist who first formally described the species, named it after Haiti where the specimen he examined was collected.

Description

It is a bush reaching 1.5 meters in height. Its membranous leaves are 4-6 by 0.7-1.5 centimeters and are rounded or shallowly notched at their tip. The leaf margins are slightly rolled under. The leaves are dull, pale green on their underside. The leaves have 8-10 pairs of secondary veins emanating from their midribs. Its petioles have a channel on their upper surface, are covered with fine hairs, often curve backwards, and are 2-2.5 millimeters long. Its solitary (sometimes in pairs) flowers are on 1-2 millimeter peduncles that emerge from older leafless branches. Its triangular sepals are 1 millimeters long and covered in brown shaggy hairs. Its 3 oblong, outer petals are 1 centimeter long with rounded tips. The petals have shaggy brown hair on their outer surface. Its stamen are 1.5-1.7 millimeters long with anthers that are 1 millimeters long. Its pistils are 1.7 millimeters long with hairy ovaries and heart-shaped stigmas.[2]
