Chamaecyparis obtusa information
DescriptionChamaecyparis obtusa (hinoki) is native to japan and a very important conifer in Japanese forestry due to its high wood quality.
It belong to Cupressaceae sensu lato (s.l.), and molecular phylogenetic analysis suggested that it is closely related to C. japonica (SUGI) (Tsumura et al. 1995; Kusumi et al. 2000).
As well as C. japonica, C. obtusa has 11 pairs of chromosomes but the estimated C-values is slightly smaller than C.japonica ( ~10000 Mbp; Hizume et al. 2001). C. obtusa is a monoecious species.
Recently, the allergic reactions caused by its pollen are also reported.
