1. "Compendium of Materia Medica": "The Catalpa tree grows in valleys and is also planted in gardens and forests for its timber. It is similar to the Chinese catalpa tree but with slight differences, like the body of a pine tree in cypress leaves. Su Jing mistakenly considered the two trees as one."2. "Emergency Materia Medica": "The Catalpa tree can be found in certain areas, such as Liangjiachong Valley in Mixian County. The trees there are very tall and large, and their wood can be used to make musical instruments. The leaves resemble those of the Chinese parasol tree but are thinner and smaller, with triangular tips and white flowers. The taste is sweet.
