Juniperus thurifera (Spanish juniper) is a species of juniper native to the mountains of the western Mediterranean region, from southern France (including Corsica) across eastern and central Spain to Morocco and locally in northern Algeria.[3][4]
It is a large shrub or tree reaching 6–20 m tall, with a trunk up to 2 m diameter and a broadly conical to rounded or irregular crown. The foliage is strongly aromatic with a spicy-resinous scent. The leaves are of two forms: juvenile needle-like leaves 8–10 mm long on seedlings and irregularly on adult plants, and adult-scale leaves 0.6–3 mm long on older plants; they are arranged in decussate opposite pairs. It is dioecious with separate male and female plants. The cones are berry-like, 7–12 mm in diameter, blue-black with a whitish waxy bloom, and contain 1-4 seeds; they are mature in about 18 months. The male cones are 3–4 mm long, and shed their pollen in early spring.[3][4][5][6]
There are two varieties, regarded as distinct by some authors,[3][5] but not by others:[4]
- Juniperus thurifera var. thurifera. Spain, France. Mature cones 8–12 mm, with 2-4 seeds.
- Juniperus thurifera var. africana Maire. Morocco, Algeria. Mature cones 7–8 mm, with 1-2 seeds.
Overall, the species is not considered threatened with healthy population in Spain;[7] however, the African population is threatened by severe overgrazing, mainly by goats, and is listed as Endangered.[3][5]
In the Sierra de Solorio there is the largest Spanish Juniper forest in Europe.[8]
