Juniperus oxycedrus, vernacularly called Cade, cade juniper, prickly juniper, prickly cedar, or sharp cedar, is a species of juniper, native across the Mediterranean region, growing on a variety of rocky sites from sea level. [3] [1] The specific epithet oxycedrus means "sharp cedar" and this species may have been the original cedar or cedrus of the ancient Greeks. [4] [5]

Description

Juniperus oxycedrus is very variable in shape, forming a spreading shrub 2–3 metres (6+12–10 feet) tall to a small erect tree 10–15 m (33–49 ft) tall. It has needle-like leaves in whorls of three; the leaves are green, 5–20 millimetres (1434 inch) long and 1–2 mm (132332 in) 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 berry-like, green ripening in 18 months to orange-red with a variable pink waxy coating; they are spherical, 7–12 mm (1412 in) diameter, and have three or six fused scales in 1–2 whorls, three of the scales with a single seed. The seeds are dispersed when birds eat the cones, digesting the fleshy scales and passing the hard seeds in their droppings. The pollen cones are yellow, 2–3 mm (11618 in) long, and fall soon after shedding their pollen in late winter or early spring. [3] [6] [7]

Subspecies

As to be expected from the wide range, J. oxycedrus is very variable, and multiple subspecies have been recognised. [3] However, multiple studies have found the subspecies not to be closely related to one another, [6] [8] [9] [10] [11] [12] resulting in the recognition of multiple species: [6] [10] [11] [12]

An additional variety or subspecies J. oxycedrus var. badia H.Gay (syn. J. oxycedrus subsp. badia (H.Gay) Debeaux) is distinguished on the basis of larger cones (10–13 mm or 3812 in diameter), tinged purple when mature; it is described from northern Algeria, and also reported from Portugal and Spain. [3] [6]

Other close relatives of J. oxycedrus include Juniperus brevifolia on the Azores, Juniperus cedrus on the Canary Islands and Juniperus formosana in eastern Asia. [3] [6]

Uses

Cade oil is the essential oil obtained through destructive distillation of the wood of this shrub. It is a dark, aromatic oil with a strong smoky smell which is used in some cosmetics and (traditional) skin treatment drugs, as well as incense. [13] [14] Cade oil has, on rare occasions, caused severe allergic reactions in infants. [15]
