What you need is botanical illustrations or flora. You can go to the local library to find ***8 volumes of Illustration of Chinese Higher Plants, including 5 volumes of illustrations, 2 volumes of supplements, and the key to families and genera 1 volume; It would be better if we can find the local flora such as Shandong flora or Yimeng mountain flora. I think there should be. I also searched the Internet for an electronic retrieval table or picture book, but I couldn't find them.
