French author Bernadette Pourquié and illustrator Cécile Gambini choreograph an illustrated tour of the world’s greatest arboreal wonders, from species that have witnessed the dinosaurs roam this Earth to exotic marvels like Brazil’s “Walking Tree” (Red Mangrove) and the Philippines’ “Rainbow Tree” (Mindanao gum tree) to underappreciated procurers of human delights, such as the sapodilla tree that gives us chewing gum and the cocoa tree without which there would be no chocolate.
