Pterospermum acerifolium

Pterospermum acerifolium, commonly known as the maple-leaved bayur, is a robust deciduous tree belonging to the family Malvaceae. Known for its massive size and ornamental foliage, it is a significant species in the tropical forests of Asia, valued for both its physical stature and ecological contributions.

The native range of this species extends across the Indian subcontinent, Myanmar, and parts of Southern China. It thrives in warm, humid climates, typically occurring in mixed forests and along riverbanks where soil moisture is consistent throughout the growing season.

Botanically, the tree is characterized by its large, leathery, lobed leaves that mimic the shape of maple leaves, and its impressive, fragrant flowers. The flowers are notable for their nocturnal bloom, featuring long, narrow sepals that expand to reveal a central column, designed to attract specific night-flying moths.

Cultivation requires deep, fertile, and well-drained loamy soils to support the tree's extensive root system. It is intolerant of frost and requires protection from extreme temperature drops. In an agricultural or horticultural setting, regular pruning is often necessary to maintain the structure of the canopy and ensure the plant remains stable in exposed environments.

Economically, Pterospermum acerifolium is utilized for its wood, which is durable, lightweight, and suitable for furniture making and interior woodwork. Beyond timber production, the tree serves as a vital component in reforestation projects and urban forestry due to its excellent shading capabilities and resistance to minor air pollutants.
