On the cover: Over the past decade and more, Dan Mahr has organized field trips to succulent-rich areas of the globe. As well as new plants, participants also experience new cultures and cuisines. Sometimes offerings are chili-fried caterpillars, other times more interesting fare, such as mezcal, made from Agave angustifolia, seen here growing by the sea.
