How to Identify Baobab Tree Varieties

The baobab tree, also known as the “tree of life,” is a remarkable and iconic tree found in various regions across Africa, Madagascar, and Australia. With its distinctive bottle-shaped trunk and unique appearance, the baobab tree is a symbol of strength, longevity, and resilience. There are nine different species of baobab trees, each with its own characteristics and features that set them apart. In this article, we will discuss how to identify different baobab tree varieties based on their key distinguishing features.

1. Adansonia digitata (African Baobab)

The African baobab is perhaps the most well-known and easily recognizable species of baobab trees. It is characterized by its massive size, with trunks that can reach up to 30 meters in circumference. The bark of the African baobab is smooth and greyish-brown when young, becoming rough and dark grey as it ages. The leaves are compound and palmate, with five to seven leaflets arranged like fingers on a hand. The flowers are large and white, turning into hard-shelled fruits that resemble gourds.

2. Adansonia grandidieri (Grandidier’s Baobab)

Grandidier’s baobab is native to Madagascar and is known for its slender trunk and crown of leaves that resemble an upside-down tree. The trunk of this species is relatively smooth and pale grey in color, with distinctive vertical lines running down its length. The leaves are compound and pinnate, with numerous small leaflets arranged along a central axis. The flowers of Grandidier’s baobab are white or pale pink, and the fruits are elongated and slightly curved.

3. Adansonia rubrostipa (Fony Baobab)

The Fony baobab is a rare species found only in western Madagascar. It is distinguished by its reddish bark, which peels off in thin strips to reveal a smooth greenish-grey surface underneath. The leaves of the Fony baobab are compound and palmate, with three to five leaflets that are glossy green on top and silvery-white underneath. The flowers are small and yellowish-green, turning into woody fruits with a velvety texture.

4. Adansonia gregorii (Boab)

The Boab tree, also known as the Australian baobab, is found in the Kimberley region of Western Australia. It has a distinctive swollen trunk that tapers towards the top, giving it a bottle-like appearance. The bark is rough and reddish-brown, with irregular patterns and textures. The leaves of the Boab tree are compound and palmate, with five to nine leaflets that are dark green above and silvery-white below. The flowers are white or cream-colored, followed by large woody fruits filled with seeds.

5. Adansonia suarezensis (Suarez Baobab)

The Suarez baobab is endemic to the island of Madagascar and is known for its massive size and robust trunk. The bark of this species is thick and deeply fissured, with a reddish-brown coloration that darkens with age. The leaves of the Suarez baobab are compound and palmate, with five to seven leaflets that are leathery and dark green in color. The flowers are large and white, turning into oval-shaped fruits covered in a fibrous outer layer.
