On the cover:The two plants in the cover photograph taken by Jim Mauseth are the cactus Matucana weberbaueri and the spikemoss Selaginella (probably S. peruviana) in northwest Peru. Land plants evolved from green algae about 420 million years ago and their descendants differentiated into two distinct evolutionary lines: cacti and all other seed plants (along with ferns) are part of one line whereas spikemosses and clubmosses are part of the other (a line that never evolved to have flowers or seeds). The spikemoss is the true desert survivor in the photo: it could survive without the Matucana, but its sprawling, highly branched body makes a moist "soil" which helps seedlings of Matucana survive.
