Goniothalamus gabriacianus is a species of plant in the family Annonaceae. It is native to Cambodia, the province of Hainan China, Laos, Thailand and Vietnam.[1] Henri Ernest Baillon the French botanist who first formally described the species using the basionym Oxymitra gabriaciana, named it after Paul-Pierre Gabriac, a French civil servant in Vietnam, who provided one of the specimens that he examined.[2]

Description

It is a bush reaching 3 to 4 meters in height. Its smooth, striated, gray branches have sparse fine hairs when young. Its membranous, broad, lance-shaped leaves are 8–22 by 3–6.5 centimeters and come to a tapering point at their tip. Both surfaces of the leaves are smooth, the upper surfaces are shiny, and the lower surface is more pallid. Its smooth, wrinkled petioles are 1 centimeter long and have a channel on their upper side. Its solitary flowers are axillary and born on 0.5 centimeter-long pedicels. It has 3 sepals that are 5 millimeters long and come to a point at their tip. The sepals are sparsely hairy on the outside and smooth on the inside. Its 6 petals are arranged in two rows of 3. The fleshy, oval outer petals are 12 millimeters long and have course rust-colored hairs. The inner petals are 9–10 millimeters long. Its flowers have numerous stamens with linear anthers. Its flowers have numerous carpels. Its ovaries have 2 locules.[3][4]
