Habit: Perennial herb, shrub, glabrous. Stem: generally < 20 cm, +- angled at least when young, +- yellow, +- green, brown, purple; branches whorled or in 1 plane. Leaf: < 1 mm, scale-like. Inflorescence: generally spikes, peduncle short; flowers generally opposite, 4-ranked, less often whorled or 1, terminal. Staminate Flower: perianth parts generally 3--4; anthers +- 1-chambered. Pistillate Flower: perianth parts 2, persistent, minute.

Species In Genus: 26 species: temperate, tropics northern hemisphere. Etymology: (Greek: juniper, life) Note: Most important of timber pathogens; most species cause abnormal branching (witches' brooms) in hosts.
