Haldina cordifolia (Roxb.) Ridsdale: A Timber Species and Its Significance

Abstract

Haldina cordifolia (syn. Adina cordifolia), commonly known as haldu, is a multipurpose deciduous tree species of immense ecological, economic, and medicinal value. With the growing demand for quality timber, pressure on natural forests has increased, underscoring the significance of this species for sustainable forestry practices. Belonging to the family Rubiaceae, H. cordifolia is widely distributed across the Indian subcontinent and Southeast Asia, thriving in tropical deciduous forests. Its timber is highly valued for durability, fine grain, and its characteristic yellow hue, making it suitable for the manufacture of furniture, flooring, panelling, construction works, turnery, bobbins, and agricultural tools. In addition to timber, the bark serves as a source of natural yellow dye for wool and linen. It exhibits antiseptic properties, while the roots are traditionally used to treat dysentery, demonstrating its strong ethnomedicinal relevance. Silviculturally, the species is promising for plantation development due to its adaptability to diverse site conditions, moderate growth, and wide multipurpose utility. Efficient propagation relies on sound knowledge of its reproductive biology, breeding systems, and seed technology, as successful seed collection, processing, and storage are essential for maintaining viability and supporting large-scale afforestation. Furthermore, phytochemical investigations have revealed the presence of bioactive compounds, broadening its potential pharmacological applications beyond traditional medicine. Given its combined timber, non-timber, and medicinal values, H. cordifolia stands as a valuable forest resource with high socio-economic and ecological significance. This article aims to provide a comprehensive account of the taxonomy, geographical distribution, botanical features, reproductive biology, breeding systems, seed collection and processing techniques, wood properties, plantation establishment strategies, growth performance, phytochemistry, and therapeutic applications of this important species, thereby supporting its sustainable utilization and conservation.
