Holmskioldia
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.
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
