Notes#

Identity. The tea research institute describes Qingxin Wulong as an introduced mainland cultivar, with established use for oolong and especially Baozhong. The precise connection to Aijiao Wulong and the historical sequence of selection in Taiwan remain unconfirmed in the original sources examined for this audit.

Numbered cultivars. Qingxin Wulong is distinct from TTES 17, Bailu. The science education centre records Bailu as Tainung 335 crossed with Tainung 1958 and named in 1983. A seller’s use of “TRES #17” for Qingxin Wulong should therefore not be treated as a botanical synonym.
