 +"It is closely related to Juniperus communis (common juniper) and Juniperus conferta (shore juniper), the latter sometimes treated as a variety or subspecies of J. rigida." [[https://en.wikipedia.org/wiki/Juniperus_rigida|wikipedia]]
  
 Evergreen, dioecious shrub or small tree, up to 10m high, native to northern China, Korea, Japan, and the far southeast of Russia; leaves in whorls of 3, dark green, needle-like, 1-2cm long, V-shaped cross-section, with a narrow white stomatal band above; "Seed cones axillary on very short stalks, stalks densely clothed with small scaly leaves, young cones green, ripening to light brown-blue or blue-black with a strong resinous odor, globose to ovoid, 6-10 mm across with (2-)3 seeds."

 +Main components of the leaf oils of J. rigida var. conferta, Tottori sand dunes, Japan (CF), cv. Blue Pacific (BP), the Newport Beach, CA juniper (NpB), cv. Emerald Sea (EmS), and J. rigida, Honshu, Japan (RG) were α-pinene (9.8-62.3%), myrcene (1.6-8.4%), bornyl acetate (0.6-7.5%), β-pinene (1.4-6.9%), limonene (1.6-6.0%), β-phellandrene (0.2-5.5%), and isoabienol (0-63.9%). The oil of cv. Emerald Sea is dominated by isoabienol (63.9%) and is clearly, quite different from cv. Blue Pacific, and isoabienol (14.5%) is also a major compound in the oil of escaped juniper from Newport Beach, CA. \\

 Main components of the supercritical CO2 extract of J. rigida leaves from China were caryophyllene (13.1%), humulene (11.7%), caryophyllene oxide (10.3%), (E)-nerolidol (6.5%) and germacrene D (6.5%). The essential oil exhibited significant antibacterial activity against K. pneumoniae. \\ Main components of the supercritical CO2 extract of J. rigida leaves from China were caryophyllene (13.1%), humulene (11.7%), caryophyllene oxide (10.3%), (E)-nerolidol (6.5%) and germacrene D (6.5%).
