On the cover: Sedum sinforosanum is described in this issue, and this photo by Jeronimo Reyes Santiago shows details that would be easily overlooked without magnification. The lustre of the surface of the petals and the color of the anthers underneath the pollen would otherwise go unnoticed. It is also possible to see that the flower in the center of the picture has four stigma lobes, while the one below it has five. .
