A new hybrid, Artemisia x wurzellii C. M. lames & Stace hybr. nov., is described between A. vulgaris and the Chinese A. verlotiorum.. Fifteen localities are known in eastern London, and one in northern West Kent, but there is no convincing evidence that the hybrid arose in. situ at any of them. Characters distinguishing the three taxa are summarized. Chromosome counts indicate that A. vulgaris is a hypodiploid and A. verlotiorulI1 a hypohexaploid. Artemisia x lVurzellii has the expected chromosome number 2n = 34 (hypotetraploid).
