Holmskioldia is a genus of flowering plants in the mint family, Lamiaceae. It is native to the Himalayas (India, Pakistan, Nepal, Bhutan, Bangladesh, Myanmar) but widely cultivated as an ornamental and naturalized in many places (Southeast Asia, New Caledonia, Hawaii, Mexico, West Indies, Venezuela, etc.) It contains only one known species, Holmskioldia sanguinea, commonly called the Chinese hat plant, cup-and-saucer-plant or mandarin's hat.[1][2][3][4][5]

The genus name commemorates Johan Theodor Holmskiold (1731-1793), a Danish botanist who wrote Beata ruris otia fungis Danicis, published in two volumes in 1790 and 1799.[1]
