There are then three varieties; Picea asperata var. aurantiaca (Masters) B.K. Boom; Picea asperata var. heterolepis (Rehder & Wilson) Cheng ex Rehder (syn: P. heterolepis Rehder & Wilson; P. asperata var. nobilis Rehder & Wilson); and P. asperata var. ponderosa Rehder & Wilson.DescriptionRangeChina: SE Qinghai, NE of Qinghai Hu (Lake Kokonor), Gansu, Sichuan, Ningxia (Helan Shan), & SW Shaanxi (2).Big TreeOldestDendrochronologyEthnobotanyObservationsRemarksVar. aurantiaca is listed by the WCMC as endangered. It is "confined to a small area west of Kangding in Sichuan. Forests in this area are increasingly under pressure from indiscriminate logging. Populations have declined and, as yet, there is no protection for the species" (4).Citations(1) Silba 1986.(2) Farjon 1990. (3) Cheng & Fu 1978. (4) World Conservation Monitoring Centre - Trees. |
