木綿志手, Yū-shide, means "Sacred Ceremonial Cloth Streamers." In Shinto ceremonies, a sacred white cloth, made usually of Mulberry bark but sometimes combined with cotton, is called 木綿, yū cloth. "Shide" are the zig-zag streamers made from the yū cloth; but this word is now spelled 紙垂 or 四手. The spelling here, 志手, shide, is either an ateji (phonetic spelling) or an earlier, poetic spelling which has been lost. Regardless, it works perfectly as an ateji to give the epithet, Yū-shide. Note that Momenshide has been made the synonym to Yū-shide, because this latter is both how it appeared in the 1882 list, and how Yano and Nakajima give it. We give priority to Japanese sources for maples of Japanese origin. (ED)
