The Herbarium at London’s Royal Botanic Gardens in Kew is a vast, Victorian maze filled with arcane books, learned scientists, and cabinet after cabinet of cataloged plants. Taking visual cues from the alluring intricacies of a Wes Anderson movie, this elegant short, “The Plant Family Tree,” is the fifth in the series Beyond the Gardens, created by the London-based studio, Lonelyleap. Coinciding with this summer’s IncrEdibles festival that runs through September, the series was designed to expose Kew’s rarely seen research aspect, and uncovers a haven from the hubbub of tourists outside. It tells the story of an institution that has played an integral role in the discovery of new species since it opened in 1853, with seven million specimens held in its many wings. “It’s a fantastic place because of all the history associated with the discovery of immensely diverse plants in the tropics,” enthuses Mark Chase, the film’s narrator and one of most prominent scientists to have worked at the gardens, currently serving as Director of Kew’s Jodrell Laboratory. “It helps us understand both the diversity of things we’ve got out there and what we have to do to preserve it.”
