Illustration:Garhadiolus papposus ( Asteraceae ) is one of the common early-spring ephemeral species widely distributed in temperate desert. This species grows only in the Junggar Desert in China. It produces three types of achenes in one infructescence that differ in morphology and dispersal behavior. To better understand how this species is adapted to the desert habitat, Sun et al . observed the morphological and dispersal traits of its achenes as part of adaptive strategies for the desert. For details see pages 353–361 of this issue. (Photographed by Huazhi Sun and Dunyan Tan)
