What are the morphological characteristics of this plant?
Dillenia indica has large, leathery, obovate leaves that measure up to 30 centimeters in length and are characterized by prominent, parallel secondary veins. The plant grows as a medium to large tree with spreading branches and a thick trunk. Its flowers are showy and consist of numerous white petals arranged around a central cluster of numerous stamens. Following pollination, the plant develops a distinctive large, fleshy, and many-seeded fruit that is often referred to as the elephant apple. The bark is typically greyish and can become deeply fissured as the tree matures.
What is the geographical distribution of this plant?
This plant is native to the tropical regions of South and Southeast Asia, specifically occurring in countries such as India, Sri Lanka, Myanmar, Thailand, and parts of Indonesia. It typically thrives in moist, lowland tropical forests and along the banks of streams or rivers where humidity is high. Within its natural range, it is most frequently found in the evergreen and semi-evergreen forest ecosystems of the Indian subcontinent. The species prefers well-drained, nutrient-rich soils that are characteristic of these warm, wet environments. Because of these specific climatic requirements, its distribution is strictly limited to the equatorial and subtropical zones of the region.
How is this plant cultivated?
This plant grows best in tropical climates with well-drained, acidic soils and high humidity levels.
It requires consistent moisture and partial shade to thrive during its early developmental stages. Once established, the plant can tolerate full sun if the soil remains sufficiently damp to prevent root stress. Regular organic fertilization helps support its large, leathery leaves and the production of its distinctive large white flowers.
Proper drainage is essential to prevent root rot in the heavy soils common to its native habitats.

According to a study published by "Microbial pathogenesis", Dillenia indica is a medicinal tree of the Dilleniaceae. The flower extract of this plant was used for the synthesis of silver nanoparticles under optimal conditions of 2 mM AgNO3, pH 4.5, and a 48-h reaction time. These nanoparticles exhibited an average size of 50.17 nm with a polydispersity index value of 0.298 and a zeta potential of -24.9 mV. The characteristic band was observed at a wavelength of 435 nm, while Energy Dispersive X-Ray showed an absorption peak approximately at 3 keV. When combined with antibiotics, the nanoparticles were maximum effective against Shigella boydii (16.07 ± 0.35) and Klebsiella pneumoniae (15.03 ± 0.20). Additionally, AgNPs alone showed maximum inhibition for methicillin-resistant Staphylococcus aureus (19.97 ± 0.20 mm) and Enterococcus faecium (19.80 ± 0.15 mm).
