|discussion=<p>Species 5 (1 in the flora).</p><!--
--><p>G. Mansion (2004) and Mansion and L. Struwe (2004) inferred from molecular studies that Schenkia is more closely related to Zeltnera and the European Exaculum Caruel than to Centaurium in the narrow sense. The stigma morphology of Schenkia is similar to that of Zeltnera.</p><!--
--><p>Schenkia differs from Centaurium and Zeltnera most distinctly in its spicate inflorescences, although the inflorescence of S. spicata is often dichasial at the one or two most proximal divisions. Conversely, the inflorescences of some Zeltnera species, such as Z. muehlenbergii, are distally monochasial with the pedicels short or none. Although Schenkia generally differs from Zeltnera in having the stamens inserted in rather than below the sinuses of the corolla, S. spicata varies in this respect, sometimes having the stamens inserted slightly below the sinuses (G. Mansion 2004).</p>
