Dr. Daniela Cristina Zappi is a Brazilian botanist, plant collector, and research scientist at the herbarium of the Royal Botanic Gardens, Kew noted for studying and describing Neotropical flora, Rubiaceae, and Cactaceae. She has described over 90 species, most recently a new species in the cactus genus Uebelmannia (U.nuda). 

In this episode of Crime Pays, we discuss the different biomes and plant communities of Brazil, what "ecological islands" are, the biogeography of the cactus family, bat pollination in Pilosocereus, edaphic endemism in "ironstone" habitats of Northern Brazil and how iron-rich soils affect the evolution of the plants that grow on them, and why truckstop food in Brazil is not only tasty but also so damn healthy.
