薄雲, Usu-gumo, means "Wisps of Cloud" (Royall Tyler, 2001). It is the title of Chapter 19 of Murasaki Shikibu's masterpiece, "The Tale of Genji." The morphology and changing nature of this unusual and highly prized cultivar, with its prominent veins surrounded by ethereal, speckled light green, evolving, as if from dawn from the pinks of spring, perfectly reflect the transience of the name.Note the rendaku, consonant voicing change, that moves the pronunciation from kumo to gumo. (ED) Commonly Usugumo in the US.

Usu gumo, (sometimes called the Bat Wing maple in the USA), is variegated A. pictum with fine dots of white. Spring color is very pink, and the leaves curl like little hands; fall color is a butter yellow. It is difficult to propagate and rather slow growing, topping out at about 12'. (DSN, as Usugumo)
