Natural range

Juniperus drupacea, the Syrian juniper, is a species of

Mediterranean region from southern Greece (mount Parnon in the Peloponnese), southern Turkey, western Syria, and Lebanon, growing on rocky sites from 800–1,700 metres (2,600–5,600 feet) in altitude. The species is the sole member of Juniperus sect. Caryocedrus.,[2][3] which is sometimes recognised as genus Arceuthos.[4]

Description

Juniperus drupacea is the tallest species of juniper, forming a conical

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, 20–27 mm (34–1 in) long and 20–25 mm diameter, and have six or nine fused scales in 2–3 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 5–20 cones together, yellow, 3–4 mm long, and fall soon after shedding their pollen in early spring.

Taxonomy

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.
