There are rare stands of old-growth Douglas fir and western redcedar ("Thuja plicata"). "Thuja plicata" is among the most widespread trees in the Pacific Northwest. The wood of "Thuja plicata" is commonly used for guitar sound boards. "Thuja" are evergreen trees growing from tall, with stringy-textured reddish-brown bark. The name was applied to the white cedar and its genus, "Thuja", by Linnaeus (1753). Native Americans and early European explorers used "Thuja" leaves as a cure for scurvy. But it is only distantly related to the genus "Thuja". It also occurs on some varieties of ornamental "Thuja". The genus is related to the "Thuja", and has similar overlapping scale-leaves. But the "Wang-hsiang" fears the tiger and the thuja. Thus the tiger and thuja are placed before the tomb.
