Abstract
Studies were made on the morphology, growth characters, growth and development, and santonin content of the genus Artemisia, majority of which belong to section Seriphidium, in order to find plants growable in Japan. A. kurramensis Qaz. of Pakistan was cultivated on trial and subsequent studies showed that its cultivation was possible. The optimal temperature of germination is 10-15°. The number of chromosomes in A. kurramensis is 2n=18, while that of santonin-free A. maritima growing side by side with the former, is 2n=36. Hence, these plants belong to two cytogenetically distinct species of Artemisia.
