Abstract

Taiwan cypress burl wood figures (BWFs) refer to the wood figures (WFs) on the burl section of Chamaecyparis formosensis and Chamaecyparis obtusa var. formosana. This study investigated the relationships between the micropatterns of Taiwan cypress BWFs and WFs. The microscopic results of various BWF patterns indicated that the "water-ripple figure approximates a wavy figure", "sliver-ripple figure approximates a mottled figure", "peanut-like figure approximates a blister figure", "phoenix tail-like figure approximates a crotch figure", and "nail and thorn-like figure approximates a burl figure". The water-ripple, sliver-ripple, peanut-like, and phoenix tail-like figures had the bright band pattern like a "flash light". The nail-like figure had a dot pattern like a "nail dot". The thorn-like figure had both the "flash light and nail dot". The bright band, nail-like and thorn-like figures were induced three types of BWFs. The bright band was the difference between the patterns on both orientations of the tracheid, longitudinal and cross sections, where the light projected on the surface and there were different lusters due to the degree of reflection, but most compositions were longitudinal tracheid. The nail-like figures visually presented some of dark dot patterns as a lot of inclusions accumulated in each orientation of tracheid. The microscopic cellular morphology of various BWFs; therefore, are able to cover the different arrangements and patterns of the tracheid, the amount or different patterns of the inclusions, and even different patterns of wood ray arrangements.
