Juniperus rigida Siebold & Zucc. - Cupressaceae - temple juniper, Igel-Wacholder

Evergreen shrub or small tree, up to 10m high, native to northern China, Korea, Japan, and the far southeast of Russia.

„The composition of the leaf oils of Juniperus rigida from northeast China, Japan and Korea are reported. The Japanese samples were very similar to previous literature reports being rich in bornyl acetate (40.5–59.0%) and α-pinene (13.5–15.4%), but the samples from northeast China and Korea showed geographical differentiation in the production of increased amounts of α-pinene (39.7% and 53.5% respectively) and reduced amounts of bornyl acetate (1.3% and 2.8% respectively).“
