Durio lanceolatus

Иллюстрация дуриана Durio lanceolatus

Durio lanceolatus is a species of tree in the Malvaceae family, which is part of the Durio genus, known for producing the fruit commonly referred to as durian. This particular species is one of the less widely known or cultivated members of the durian family, which includes several species that produce edible fruits highly prized in Southeast Asia for their unique flavors and textures. Unlike its more famous relative, Durio zibethinus, which is widely cultivated and known simply as "durian" or "king of fruits," Durio lanceolatus has not achieved the same level of popularity or commercial cultivation.

Description

Durio lanceolatus is a tropical tree that can reach heights of up to 25-30 meters. It has a straight trunk with a smooth, grey bark. The leaves of Durio lanceolatus are lanceolate, meaning they are shaped like a lance, with a pointed tip and a wider base, and can be up to 25 cm in length. The flowers of the tree are white to pale yellow, and they grow directly from the older branches, a characteristic known as cauliflory. The fruit of Durio lanceolatus is covered in hard, sharp spines, similar to other durian species, and contains a soft, edible pulp surrounding large seeds.

Distribution and Habitat

Durio lanceolatus is native to the tropical forests of Borneo. Its distribution is limited to specific regions within this island, where it grows at elevations up to 800 meters. The tree prefers humid, tropical climates and is often found in primary and secondary forests. Due to its specific habitat requirements and limited range, Durio lanceolatus is considered to be of conservation concern, although it has not been extensively studied.

Cultivation and Uses

The cultivation of Durio lanceolatus is limited compared to other durian species, primarily due to its lesser-known status and the preference for the more commercially viable Durio zibethinus. However, in areas where it is grown, the fruit of Durio lanceolatus is appreciated for its flavor and is consumed locally. The tree is also valued for its wood and is sometimes planted for timber production.

Conservation Status

There is limited information on the conservation status of Durio lanceolatus. Its restricted distribution and the ongoing deforestation in Borneo pose potential threats to its natural habitat. Conservation efforts for Durio lanceolatus and other less common durian species are important to ensure their survival and to maintain biodiversity within tropical forest ecosystems.
