Where can I look up plant name information?

First, you need a retrieval book. Professional books are available in major bookstores. Then you need to get the specimen of the plant you want to retrieve, preferably the one with roots, leaves, flowers and fruits. Then you can compare search!

For example, it is generally confirmed whether it is a monocotyledonous plant or a dicotyledonous plant. The book will show you two directions with page numbers, and the path of each book is different. Then confirm whether the ovary is superior or inferior, whether it is inflorescence, whether there is calyx, whether the leaves are opposite or alternate, whether the veins are parallel or reticulate, and so on. Generally, you can find the scientific name of this plant with 5-6 characteristics at most.
