Juniperus drupacea, the Syrian juniper, is a species of juniper native to the eastern Mediterranean region from southern Greece (mount Parnon in the Peloponnese), southern Turkey, western Syria, Lebanon, and northern Israel, growing on rocky sites from in altitude. The species is the sole member of Juniperus sect. Caryocedrus., which is sometimes recognised as genus Arceuthos.
Juniperus drupacea is the tallest species of juniper, forming a conical tree tall, exceptionally up to , and with a trunk up to thick. It has needle-like leaves in whorls of three; the leaves are green, long and 2âÂÂ3 mm broad, with a double white stomatal band (split by a green midrib) on the inner surface. It is usually dioecious, with separate male and female plants.
The seed cones are the largest of any juniper, berry-like but hard and dry, green ripening in about 25 months to dark purple-brown with a pale blue waxy coating; they are ovoid to spherical, long and 20âÂÂ25 mm diameter, and have six or nine fused scales in 2âÂÂ3 whorls, each scale with a slightly raised apex. The three apical scales each bear a single seed, but with the three seeds fused together into a single nut-like shell. The male cones are produced in clusters (unlike any other juniper) of 5âÂÂ20 cones together, yellow, 3âÂÂ4 mm long, and fall soon after shedding their pollen in early spring.
Because of its distinct cones with the seeds fused three together and the clustered male cones, it has sometimes been treated in a distinct genus of its own as Arceuthos drupacea (Labill.) Antoine & Kotschy, but genetic studies have shown it is fairly closely related to J. macrocarpa and J. oxycedrus.
