Pseudotsuga sinensis var. wilsoniana
Native to (or naturalized in) Oregon:
- Conifer, evergreen tree, to about 65-80 ft (20-25 m) tall, bark thick, corky, deeply fissured into scaly ridges. Young shoots red-brown, becoming more gray; buds oval-conical, apex pointed. Leaves flat, linear, slightly curved, to about 5 cm long and 0.15 cm wide, apex emarginate (notch), midrib grooved the entire length above, keeled with 2 stomatal bands beneath. Cones pendant, about 6 cm long and 3 cm wide, scale nearly 3 cm wide and bract scales with reflexed tips, with long, awl-shaped middle lobes and 2 triangular, short acuminate side lobes. Seeds winged, about 1.5-2 mm long.
- Hardy to USDA Zone 7 or lower Native to China and Taiwan. Now mostly considered variety of Pseudotsuga sinensis [P. s. var. wilsoniana] although it can be apparently distinguished from the type variety by its gray-green, rather that white, stomatal bands and that it is native to Taiwan, whereas the "type" in found on the mainland.
- wilsoniana: named by the Japanese taxonomist Bunzo Hayata in honor of E. H. Wilson ("Chinese Wilson"), a British notaable plant collector and explorer (1876-1930). Hayata also named the so-called the Wilson's Plum Yew as Cephalotaxus wilsoniana.
