Their trunk has a large, "swollen" base and a smooth, gray bark . The palm-shaped split leaf consists of five to seven (rarely nine) partial leaves and a petiole up to 9 centimeters long . The bare partial leaves are elliptical, 6 to 12.5 inches long and 2.5 to 5 inches wide. The leaf margin is smooth.

Inflorescences and flowers

The single flowers are erect. Your ribbon-shaped to obovate sepals are 10 to 12 inches long and 1 to 1.2 inches wide. The narrow, obovate petals are white, 13.5 to 15 centimeters long and 1.5 to 2.5 centimeters wide. The numerous stamens are fused into a 2 centimeter long tube with 4.5 to 5 centimeter long corolla lobes. The stylus is longer than the stamens.

The flowering period extends from mid-November to mid-January. The flowers are pollinated by the hawkmoth Agrius convolvuli .

The brownish black fruits ripen from May to December and are spherical to ovoid.

Distribution, number of chromosomes and systematics

Adansonia gibbosa is endemic to northwestern Australia . Adansonia gibbosa is one of only two Adansonia species that originate outside of Africa and Madagascar.

The chromosome number is . ${\ displaystyle 2n = 88}$

The first description as Capparis gibbosa was made in 1842 by Allan Cunningham .

Synonyms are Adansonia rupestris Kent and Adansonia stanburyana Hochr. David A. Baum became Adansonia gregorii F. Muell. treated as a synonym of Adansonia gibbosa .

use

The fruits and leaves are eaten, the bark is used for making ropes and out of the pollen is glue made.
