Cupressus gigantea, the Tibetan cypress, is a species of conifer in the family Cupressaceae in Asia. C. gigantea was previously classified as a subspecies of Cupressus torulosa because of their similar morphological characteristics and close distribution, but have since been genetically distinguished as separate species.^[2]

Distribution

It is endemic to Southeast Tibet - China on the Qinghai-Tibetan plateau, particularly in the dry valleys of Nyang River and Yarlung Tsangpo River.^[3] Cupressus gigantea is the biggest of all Cupressus species.

King cypress

The biggest known specimen is the famous King Cypress, about 50 meters high, 5.8 meters in diameter, 0.165-acre (670 m²) of crown-projection-area; and calculated age of 2,600 years.
