Botanical referent of "Ye Lai Xiang" (夜来香)
In Chinese horticulture, 夜来香 can refer either to the night-fragrant vine *Telosma cordata* (Pergularia odoratissima) or to tuberose (*Polianthes tuberosa*, 晚香玉). Western tea glosses often translate Ye Lai Xiang as "tuberose", while T/CZTTBZ 001—2021 defines the group simply by its "natural night-blooming flower fragrance" (自然的夜来香花香味) and also files 夜合 (*Magnolia coco*, night-closing magnolia) inside the same family.
