This book was released on 1951 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
