Arisaema nilamburense Sivad.

• Genus: Arisaema
• Botanical Background: Described by the botanist abbreviated as Sivad., contributing to the modern understanding of Arisaema diversity in South Asia. Its discovery has spurred further research into the genus, particularly concerning the evolution of inflorescence structure among tropical aroids.

• Geographical Range: Indigenous to the tropical regions of South India, notably within the Western Ghats and surrounding areas.
• Environment: Thrives in moist, shaded understoreys with high humidity; well-drained, organic-rich soils and typically grows in areas with a moderate to heavy rainfall pattern.
