Acid methanol leaf extracts of all of the eleven species assigned to the Section Tridentalae of Artemisia by Beetle were chromatographed using a descending two‐dimensional method. Analysis of the resultant chromatographs showed that the presence or absence of any or all of three spots, in particular, blue (84/53), orange (80/50), and green (81/58), was consistently the same for any species or variety. These spots have been designated as species‐specific. Certain relationships on the basis of this evidence are postulated. Three additional spots which appeared on the chromatograms, blue (55/65), orange (51/70), and blue (53/79), seem to be characteristic of the Section Tridentatae . It is proposed that the three species which do not show these spots do not properly belong in this section. Preliminary evidence indicates that the species diagnostic spots are aglycones or free phenolics while the section‐diagnostic spots are possibly phenolic glycosides.
