The Indian cork tree is a tall, typically rather narrow tree with distinctive long (5-10cm) white fragrant flowers that bloom straight out and then later hang down. At a quick glance the flowers appear to have four petals, but it’s actually five with two of the petals being a bit smaller than the others and growing together as a pair. Because the flower was formerly used in some medicines, and because it’s white like their uniforms, it is the symbol of Thai nurses. It’s also the provincial tree of Chiang Rai and Phitsanulok. Though it’s not nearly as good as the real thing, the bark can be used like cork.
