蔦かつら is the 1782 spelling for Tsuta-katsura. While most epithets containing "katsura" use 桂 directly to reference the Katsura Tree (Cercidiphyllum japonicum) directly, this uses the Hiragana to spell katsura, and the dictionary notes that "hairpiece/wig", katsura, is usually written with kana only. Further, the earliest reference to 桂, the Katsura Tree, is 1974; that leads us to believe that this earlier kana refers to 鬘, a wig. In particular, "katsura" describes a wig used in traditional Kabuki and Noh plays, which would have been widely performed in 1782. With this interpretation, 蔦鬘, Tsuta-katsura, means "Ivy Wig." It would be an apt morphological epithet for many of the class of palmate-leaved weeping maples. (ED)
