Red Sandal Wood is
Pterocarpus santalinus
Pterocarpus santalinus, commonly known as red sanders or red sandalwood or sanders wood, is endemic to Southern Eastern Ghats mountain range of South India. This tree is valued for the rich red colour of its wood. The wood is not aromatic. It should not be confused with aromatic Santalum sandalwood trees that grow natively in south India. So, the correct answer is 'Pterocarpus santalinus'.
