Adansonia za, is a species of baobab in the genus Adansonia belonging to the family Bombacaceae. It was originally named in French as anadzahé.[3] Common names in Malagasy include bojy, boringy, bozy, bozybe, ringy, and za,[4] the last of which gives the plant its specific epithet.[5]

Description

Adansonia za is a large thick-stemmed (pachycaul) deciduous tree, about 10–40 metres (33–131 ft) high and about 6 metres (20 ft) in diameter. The trunk and branches have a brownish-rose colored hue. The tree is wide at the base and grows to a narrow point towards the top of the tree. Leaves are palmately lobed with up to 5 lobes per leaf. They are 5–10 centimetres (2.0–3.9 in) long and 1.5–2.5 centimetres (0.59–0.98 in) wide and the leaf margin is entire. The flower buds are long green cylinders which can resemble oversized beans and could be mistaken for a fruit. The bud opens with the curling back of the outside layer of the flower bud, revealing yellow and red petals with yellowish long stamens. The corolla is 15–20 centimetres (5.9–7.9 in) long and 1.2–1.5 centimetres (0.47–0.59 in) wide. Petals are 10–20 centimetres (3.9–7.9 in) long and 1.2–1.5 centimetres (0.47–0.59 in) wide. The flowers are musty-sweet scented. Flowering period extends from November to February. Flowers are usually pollinated by moths of the Sphingidae family. Fruits are usually ovoid with a markedly thickened peduncle. They contain kidney-shaped, laterally-flattened seeds. The seeds have an oil content of 11 percent.

Distribution

Adansonia za is endemic to southern and north-western Madagascar, where it is threatened by habitat loss.

Habitat

This plant grows in arid scrublands, in deciduous and thorn forests, and in savannah. It prefers sunny areas and well drained soils, at an elevation up to 800 metres (2,600 ft) above sea level.

Largest tree

Possibly the largest tree of this species (by circumference) grows near Reakaly village north-west from Ampanihy. The circumference of its trunk is approximately 23 metres (75 ft).[6]
