Book Description
The recently discovered redwood of China, "Metasequoia glyptostroboides" Hu & Cheng, shows close relationship to two North American trees, the coast redwood, "Sequoia sempervirens" Endlicher of the western U.S., & the swamp cypress, "Taxodium distichum" Richard of the Southeastern U.S. Foliage & cones of these living trees provide characters by which the three genera may be readily distinguished. But for nearly a century there has been confusion in the recognition of fossil specimens. The author is now able to distinguish the fossil foliage & cones of all three genera, & to assign to Metasequoia many specimens which have previously been identified as Sequoia & Taxodium. Illustrations.

Book Description
The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

Book Description
The epic story of the planet’s oldest trees and the making of the modern world Humans have always revered long-lived trees. But as historian Jared Farmer reveals in Elderflora, our veneration took a modern turn in the eighteenth century, when naturalists embarked on a quest to locate and precisely date the oldest living things on earth. The new science of tree time prompted travelers to visit ancient specimens and conservationists to protect sacred groves. Exploitation accompanied sanctification, as old-growth forests succumbed to imperial expansion and the industrial revolution. Taking us from Lebanon to New Zealand to California, Farmer surveys the complex history of the world’s oldest trees, including voices of Indigenous peoples, religious figures, and contemporary scientists who study elderflora in crisis. In a changing climate, a long future is still possible, Farmer shows, but only if we give care to young things that might grow old.
