General/Distribution: The generic name Marmoritis is resuscitated after almost 150 years in synonymy and replaces the currently accepted Phyllophyton. 5 species in the mountains of C Asia, the Himalaya and China. A very close ally of Nepeta and Glechoma L. (not in our area), but apparently meriting independent generic status on the characters of inflorescence, habit and resupinate corollas; all the species grow in screes and moraines up to very high altitudes.
