Cover Illustration: Inflorescence with flowers of purple loosestrife, Lythrum salicaria(left panel). Depending on the relative length of styles with respect to stamens within flowers, individuals are categorized into three floral morphs. The three floral morphs also differ in size and shape of stigmas (right panel). Stigmas (toplong morph, middlemid morph, and bottomshort morph, in the right panel; bar = 200 µm) are digitally false-colored computer-enhanced images from scanning electron micrographs. See Hermann et al.: Quantitative evaluation of stigma polymorphism in a tristylous weed, Lythrum salicaria(Lythraceae), pp. 11211129 in this issue. Photo credit: M. Biernacki, T. K. Mal, R. J.
