Picea crassifolia, the Qinghai spruce, is a species of conifer in the family Pinaceae. It is found only in northwestern China, in the provinces of Qinghai, Gansu, and Inner Mongolia.[2] It is an evergreen tree growing to 20–25 metres tall, with glaucous grey-green needles 12–22 mm long (but up to 35 mm in some cultivated plants) with a rhombic cross-section, not flattened. The cones are 5–11 cm long, with rounded scales. It is closely related to Picea schrenkiana which replaces it further west, and to Picea asperata to its south.[3][4]
