Abstract: The "Hengduang-Himalayan Mts.(HH)forest subkingdom" is shown to be Ice Age refuge of Artemisia L. in Quaternary era and also a more recent secondary centre of speciation. The character of the area is discussed from a floristic point of view and it is pointed that the HH may be a specieal area of concentration for Artemisia L. and a secondary centre of distribution for the genus. A catalogue of the genus arranged by floristic elements is added.
