Gāng plant-name character

𫇪 is read gāng in Mandarin and names a plant in the Classic of Mountains and Seas, an old Chinese book of mountain routes and marvels. The related form 𦱌 is listed as a grass name in Yupian, a Chinese character dictionary compiled in 543; the classic describes red stems, white flowers, grape-like fruit, and says eating it prevents foolishness. A Southern Song recipe also lists 𫇪草 as an ingredient.
