Are you talking about the difference between the leaves and roots of Ophiopogon japonicus and Ophiopogon japonicus? One is a common counterfeit of Ophiopogon japonicus: Bamboo Leaf Ophiopogon japonicus, and the other is the genuine Ophiopogon japonicus. The best distinction in shape is the broken surface: Ophiopogon japonicus has a woody core, which is relatively soft and has a sweet taste. Ophiopogon japonicus has no woody core and is hard in texture. The above is best done through comparison. Ophiopogon japonicus: pliable texture, yellow-white cross-section, translucent, and small central column. The smell is slightly fragrant, and the taste is sweet and slightly bitter.
