On the cover: The pollination of cactus flowers is accomplished by all manner of insects, of course, and many arborescent cacti have developed a mutualism with bats, who affect pollination of their large, white, nocturnal flowers. But some cacti have evolved brightly-colored tubular flowers that attract hummingbirds, who come to sip sweet nectar. Many such plants, and their zippy visitors, were encountered on the June 2008 CSSA field trip to the Brazilian states of Bahía and Minas Gerais. Susan Mahr captured thisPenalto Hermit hummingbird visiting Micranthocereus polyanthussubspecies alvinii near Morro do Chapéu. More of her work is featured on pages 130–31.

This special issue is focussed on the unique succulent plants and habitats of the vast Brazilian wilderness. We hope it serves as a useful introduction to this increasingly popular destination for cactus exploration.
